The result for HIV was positive 2 times. False positive HIV test. Is it possible to find out if you have HIV infection without tests?


False-positive HIV is not uncommon. This result occurs for many people. It is immediately worth noting that there are several reasons for this phenomenon. And false HIV is not always positive - a consequence of the body’s unpredictable reaction. Often the cause is an incorrectly conducted study, as well as medical error. It is worth noting that most often a false diagnosis of HIV is a consequence of testing carried out at home.

False HIV test at home

A false negative HIV test result most often occurs when testing at home. It is worth noting that the advantages of home test systems should not be diminished. Naturally, they do not provide the 100% accuracy results promised by some manufacturers, but their reliability is ninety-seven to ninety-eight percent. Here it is important to make an allowance for the fact that such a study must be carried out strictly according to the instructions and under extremely sterile conditions. A false HIV test can happen for a variety of reasons. Most often, the result is negative, when in fact the person has an immunodeficiency virus in the body. For what reasons could this happen? First of all, if the test system is used incorrectly. A smaller or larger amount of blood, its non-sterility and other factors can cause the infection not to be detected. Often a negative result in the presence of a terrible illness is a consequence of improper storage of tests. It's not just about pharmacy wine. It also happens that a person buys a product in a specialized institution and stores it incorrectly at home.

Is it possible to have a false positive HIV test during a home test? Yes. Such a development of events is also possible. But most often we are talking about a negative result in the presence of a disease. In what cases can the error work in the opposite direction? This is primarily influenced by the state of the immune system, which in some cases leads to the body producing antibodies without the presence of infection. Concomitant diseases of the kidneys, liver, and endocrine system can also cause a false positive result for HIV to occur during a home test. A small error in the test systems can also cause this result.

False-positive HIV: causes during pregnancy

There are two reasons for a false positive HIV test during pregnancy. It is worth noting that this picture is observed in twenty to twenty-three percent of women. Why does a pregnant woman’s body begin to produce antibodies to the immunodeficiency virus? This may be because when the egg and sperm come together, the two genetic materials are mixed. This leads to the emergence of new DNA, which is perceived by the woman’s body as foreign. The first to respond to cells invading the body is the immune system. It is she who can begin to produce antibodies, which, when analyzed, will be regarded as antibodies to the immunodeficiency virus. Can an HIV test be false positive in this case? Yes maybe. In this case, ELISA testing can mistakenly identify a terrible disease. This type of study is aimed at identifying specifically AT. And they, as you know, are similar in structure to each other.

When examining a pregnant woman for HIV, a false-positive result may also occur for another reason. The fact is that after conception the body experiences serious changes and a kind of stress. It is worth noting that if before pregnancy the immune system was in a deplorable state, then after it it is even harder. This is what can cause false HIV.

It is important to know that such a test result for the presence of antibodies to a terrible disease is not a gadfly or a basis for making a diagnosis. The doctor from the antenatal clinic with whom she is registered must explain this to a pregnant woman. This specialist must also necessarily refer the patient to the CVD or a specialized AIDS center. And already in these medical institutions the false diagnosis of HIV will be refuted.

False-positive HIV test: causes associated with diseases and pathologies of the human body

A false-positive HIV ELISA may also occur for other reasons. Enzyme immunosorbent testing is aimed at identifying antibodies to a dangerous disease. There are a number of cases when the human body begins to produce antibodies. What are the reasons for this phenomenon?

Most people who pass, for various reasons, HIV test, always hope for negative indicators. But sometimes it happens that an uninfected person has a positive result, which causes a lot of worry. Why do unreliable results occur, and how to avoid them?

Detection of infection can be done in two ways:

  • Determination of antibodies by enzyme-linked immunosorbent assay (ELISA). During the study, antibodies are sorted into obviously healthy and suspicious ones, the appearance of which can distort the results.
  • Immunoblotting is a more thorough and reliable method. It consists of separating a mixture of antigens using electrophoresis in a special gel. Then the gel plate is treated with serum containing antibodies to the virus. The analysis is then continued using ELISA.

If the patient wishes, he can donate blood for HIV anonymously. Analysis data is processed within 3 weeks.

It is worth bringing some clarity to the terminology. AIDS, or acquired immunodeficiency syndrome, is the terminal stage of HIV infection, ending in death. Unfortunately, there is currently no cure for this disease. And the human immunodeficiency virus (HIV) is the cause of AIDS. Therefore, as such , AIDS test does not give up, and the diagnosis is made on the basis of a positive HIV test and the corresponding clinical picture.

Nevertheless, a distorted result may occur in the presence of the following diseases:

  • autoimmune liver diseases;
  • pathology of the immune system;
  • chronic arthritis;
  • the presence of various viral infections;
  • oncological diseases;
  • bleeding disorders.

Blood donors also often encounter incorrect results due to the constant renewal of blood during frequent donations.

It should be remembered that the diagnosis of HIV infection is never established by one test. If you receive positive tests, you need to retake the test after about 3 months. In the absence of infection, a new virus analysis should show a negative result.

There are test systems that allow you to carry out analysis at home. According to statistics, they are the ones who most often show false positive results. There are a number of reasons for this:

  • improper storage and operation of the test system;
  • failure to maintain sterility when collecting material;
  • violation of analysis technique;
  • accompanying conditions of the body (bad habits, unhealthy diet);
  • expiration of the system's shelf life.

An undoubted advantage of using home tests is maintaining anonymity.
It is not uncommon for a positive result to be found in pregnant women. This is explained by the fact that in response to implantation, the female body begins to produce antibodies, perceiving the embryo as a foreign material. Hence the incorrect test results.

If a pregnant woman has a positive test, the doctor needs to be extremely tactful to convey this unpleasant news. It is advisable to retake the test in specialized AIDS centers.

Don't forget about the human factor. Cases where tests are mixed up are not common, but they do occur. To prevent this from happening, medical personnel need to take a more responsible approach to performing their duties.

To avoid a false positive result, when donating blood you need to follow a number of rules:

  • A few days before donating blood, you should not smoke, drink alcohol, have an active sex life, or eat poorly.
  • A recent infectious disease is the reason for postponing the test by an average of a month.
  • It is also necessary to take into account the use of medications, which can also distort the results.

In any case, a positive test is not a death sentence. And to avoid it, you need to follow safety measures and take care of your health.

Conducting research for infection with the immunodeficiency virus is stressful for any person. And all the people who receive a transcript of their HIV test results with negative results breathe a sigh of relief. However, such a result is not always reliable, and, often, the absence of a positive answer does not mean that the person is completely healthy.

Let's consider what result of an HIV test is negative, and what errors may occur during the study.

The annual increase in the number of HIV infections creates an urgent need for reliable diagnosis of the HIV virus. For this purpose, any large city has Centers for the Prevention and Control of AIDS, where testing for this infection is done absolutely free and anonymously. You can receive a transcript of the examination in your hands within 5-10 days.

The results of blood testing for this disease are usually called:

  • positive – HIV detected;
  • negative – there is no immunodeficiency virus;
  • doubtful or undeterminable.

What does an HIV negative reaction mean in different types of blood tests:

  1. Primary diagnosis of virus infection is carried out. An enzyme immunoassay detects the presence of antibodies in a patient. A negative examination result indicates that human biomaterials do not contain specific response cells produced by the human immune system when infected.
  2. The most reliable and expensive method to use is immunoblotting. It is not used routinely to diagnose HIV, but is prescribed when ELISA results are in doubt. The percentage probability of receiving a reliable answer is 98%. The remaining 2% are errors caused by irregularities in the work of medical personnel.
  3. It is rarely performed in adults. It is usually used to diagnose HIV infection of a newborn child directly at birth or while in utero. PCR can show the presence of HIV DNA and RNA immediately after infection. After conducting a polymerase chain reaction study, a person receives a result that will indicate the number of virus RNA strands detected. This factor is called “viral load”. If the amount of RNA is less than 20, then the result can be considered reliably negative.
  4. They have recently appeared on pharmacy shelves. They are test strips with diagnostic serum applied to them. The accuracy of such a study is only 80%. Therefore, if the home test system has a negative response and you have had contact with someone infected with this infection, you must in any case contact the Center for the Prevention and Control of AIDS to conduct more accurate examination methods - enzyme-linked immunosorbent assay or immunoblotting.

If the negative answer is beyond doubt, but there was still contact with the infected person or contact continues, then it would be advisable to contact the AIDS Center for advice about. It involves taking antiretroviral drugs to exclude possible infection.

Are diagnostic errors possible?

There is such a thing as the development of infection. This is a time period when the body is just beginning to fight the infection that has entered it, and the concentration of antibodies in the blood is still negligible. This period lasts on average from 14 to 60 days after infection. If you take a blood test for HIV during this period, it will be negative. For some people, it may begin only after a few months, in which case it is called the “window period” and can last up to a year and a half.

Reasons why AIDS testing may be false negative:

  1. An atypical immune reaction that can occur in the presence of other inflammatory diseases in a person.
  2. Conditions after organ transplantation. After transplantation, a person is prescribed strong immunosuppressive (immune suppressant) drugs that block the formation of antibodies to the virus.
  3. Seronegative variant of this viral infection. At the same time, there is a long incubation period after the moment of infection, and antibodies to the virus begin to be produced much later than average. The infection may not be detected in the blood for several months.
  4. At the last (or terminal) . In this case, the state of the immune system is so severely depressed that it no longer has the strength to develop a response to the presence of infection.
  5. Violations in the collection of biomaterial, its transportation and storage. This also includes violations in the use of diagnostic sera by medical personnel.

If the test response to HIV is negative and antibodies to the infection are not detected, then it is still necessary to consult a doctor about this. If a specialist has doubts when studying the results of the examination, then diagnosing blood for HIV can be repeated after 3 months.

The following factors speak for the reliability of the research results:

  • all diagnostic deadlines have been met;
  • the collection, transportation and the process of studying the biomaterial itself were carried out correctly;
  • the person did not drink alcohol, carbonated drinks, fried, fatty, spicy or salty foods.

If all the rules are followed, and the doctor does not suspect even the slightest signs of infection with the immunodeficiency virus, then the negative answer received can be considered 100% reliable.

HIV, AIDS - these abbreviations can cause panic and serious worries in any person. The resulting false-positive HIV test can have a wide variety of reasons - from objective, depending on the state of the body, to subjective, resulting from possible incompetence and negligence.

The article explains the reasons for the formation of incorrect data, features of the test, possible measures to prevent the receipt of incorrect indicators, and also provides a special view of the problem of some specialists.

Diagnosing HIV in the laboratory

If there is a reason for an HIV test, you must first take a general blood test. The laboratory will record in detail all the data, on the basis of which specialists will be able to judge the amount of antibodies in the bloodstream: their amount in case of a false positive result will be higher than the standard. However, this cannot be a reason for concern - as practice shows, high numbers may have completely different reasons.

Diagnosis consists of two stages:

  1. Screening ELISA (enzyme-linked immunosorbent assay), sorting antibodies into clearly healthy and suspicious ones, which manifest themselves ambiguously. It is at this stage that false positive results may appear.
  2. A more complete analysis is immunoblotting. The method consists of studying serum obtained by isolating plasma and red blood cells from a portion of provided blood and subsequently identifying antibodies for their cooperation with the virus. Experts recognize this method of testing for HIV detection as more effective, but it cannot be considered flawless either; the method does not provide any guarantees.

Blood sampling is carried out within 20 minutes using disposable medical instruments. The procedure can be completed anonymously or openly.

The waiting time for results is no more than 3 weeks.

For reference: HIV and AIDS are very often confused; in order to clearly understand what is being discussed, you need to understand the difference between these designations. AIDS is a disease that has an irreversible development, the vast majority of its carriers leading to a tragic ending. HIV is a virus with which a person can coexist quite peacefully for a long time, while remaining a carrier.

Reasons for a false positive test

Several factors can be the starting point for obtaining distorted data.

Various diseases can be provocateurs of false results with a “+” sign, for example:

  • Presence of infection in the upper respiratory tract;
  • Autoimmune liver diseases of a primary nature;
  • Disruption of immune processes that act as a “regulator” of the normal functioning of internal organs;
  • Severe arthritic joint damage;
  • Circulation of viruses in the body, especially influenza, hepatitis;
  • Alcoholic liver damage (mainly in men);
  • Lesions of the vascular system;
  • Sclerosis at various stages;
  • Oncology.

In many cases, the decisive influence is exerted by the characteristics of the blood - its increased density and serious problems with clotting.

Women often receive a false result for HIV during pregnancy or when donating blood during their menstrual period. An incorrect result can also be formed as a result of transplantation (at the time of adaptation of the transplanted organ to the new body), or during donation (with frequent donation of blood, its constant renewal occurs). Cross-reactions may well provoke a false-positive result: for example, antibodies begin to form in the blood, which the body does not “read” and treats them as foreign harmful carriers.

In this case, errors in HIV testing will be inevitable.

The first thing you need to understand is that the indicators of a single HIV test with a positive result cannot be completely trusted. To confirm or refute one-time information, you need to go through the procedure again, but not earlier than after 3 months. If the body is not affected by HIV infection, the result of the second test will be negative.

Testing at home

The most common way to find incorrect test results is during home testing. A false positive result for HIV is obtained due to a large number of errors, resulting in an incorrect impression of the actual state of the body. An erroneous result may be due to several reasons:

  1. Violation of the test system storage rules;
  2. Non-sterility of the material;
  3. Incorrect amount of blood for analysis;
  4. The presence of other factors (health status, dietary habits, bad habits).

A home HIV test is convenient because it allows you to maintain anonymity - not every person is ready to provide their data for fear of disclosing information if infection is detected. But, as practice shows, performing a test at home gives the highest percentage of false positive results for HIV.

False positive result in pregnant women

Errors in laboratory tests especially cause a lot of anxiety for women who are in a period of joyful and exciting anticipation of the birth of their baby.

A false positive HIV result in women during pregnancy occurs in two cases:

  1. When a new life is born in a woman’s body, the genetic materials of male and female organisms are mixed, resulting in new DNA.
  2. The female body instantly reacts to the “foreign woman” by producing its own antibodies, and during testing they will be perceived as antibodies to HIV. The result is a false positive. The only way to obtain reliable data is to conduct an enzyme-linked immunosorbent test aimed specifically at detecting antibodies.

  3. The cause of the error may be the stressful state of a pregnant woman, especially if psychological problems occurred before the moment of conception.
  4. The doctor must inform the expectant mother of the test result, but this must be done as carefully as possible, taking into account the heightened state of the female psyche (pregnancy makes a woman especially sensitive to various news). To confirm or refute the received data, a woman expecting a child must undergo examination in specialized clinics: an AIDS center, or a dermatovenerological dispensary.

If a medical error occurs

There are not many cases when the result of an HIV test is officially recognized as erroneous; such a phenomenon cannot be called widespread, but there are precedents. What is the reason for such errors?

Opinions agree that, in many ways, liability for erroneous information is the result of simple negligence and irresponsible behavior in the workplace by treatment room employees. With all due respect to the medical staff of clinics and hospitals, a positive HIV test, which subsequently turns out to be false in both positive and negative directions, can be the result of an elementary error, the notorious “human factor.”

An erroneous result can also be caused by insufficient competence of clinical laboratory specialists, violation of storage conditions for a special substance for analysis, or the use of expired materials.

A false positive result in an HIV test is a potential reason for a repeat test to eliminate the possibility of ambiguity or doubt about the reliability of the final result.

How to pass the test correctly

To obtain reliable results when taking an HIV test, you must adhere to certain prerequisites. A prerequisite for everyone is that testing must be carried out on an empty stomach.

Before the procedure you cannot:

  • Continue an active sex life;
  • Drink alcohol, drugs;
  • Eating fatty, fried, pickled and smoked foods - this diet has an extremely negative effect on blood flow.

If, before donating blood for HIV, you feel unwell or painful from a recent viral or infectious disease, a visit to the treatment room should be postponed for 1–1.5 months until complete recovery. It is noteworthy that this is one of the main reasons for obtaining an unreliable test result, since the blood contains a high content of drugs that can completely distort the study data.

HIV – the terrible truth or the “scam of the century”

Numerous venerable scientists have been debating the topic of AIDS and HIV for decades: immunologists, hematologists, infectious disease specialists and almost the entire medical community are involved in the debate. Information about the terrifying growth rate of the number of carriers of two dangerous viruses is reminiscent of reports from the front about human losses; AIDS Remembrance Day is included in the worldwide list of annual memorial dates.

Every year, an increasing number of medical specialists in different parts of the planet are mobilized to fight the “pandemic of the century.”

However, there is another point of view on the problem. Some time ago, an article appeared on the Internet that essentially refuted all currently existing ideas about these deadly diseases. It examined in detail the causes of HIV and AIDS, compared data from various sources, and provided many statistical data for comparison. Based on all of the above, the authors conclude that there is a commercial motive for the wave of fear and hysteria that has arisen around these diseases.

It is also argued that under the current system, absolutely all research data should be false positive. The article is voluminous, replete with factual material, with references to international experience. However, after its publication there was no response from specialists, there was no heated debate in the Internet community, only a few comments were made. Therefore, to trust or not to trust a publication is up to each person to decide personally.

Taking into account all the information available today about the state of affairs with HIV, one cannot make one-sided, subjective conclusions about the reasons for false testing rates. The right position is to take good care of your health, timely seek advice from specialists, and timely complete medical examination. Those people who have been diagnosed with a threatening diagnosis should not panic, but take the necessary measures to control the situation and consistent treatment.

In contact with

The HIV test is positive - however, it sounds like a death sentence for many. The presence of this epic disease indicates a viral attack that kills cells, but not the presence of AIDS.

The question of what to do if the test result is positive for HIV worries many. But, firstly, a doctor’s order to take an analysis or test for immunodeficiency does not mean that the person being examined will have a positive result. Secondly, by following healing therapy, life can continue in the same colors as before. The main thing is to detect an infection that affects the cells of the human body in time.

HIV (human immunodeficiency virus) is an infectious disease that destroys the body's immune system. The presence of a virus in a person’s blood means that a process has been launched in the body that kills healthy cells that are responsible for immunity and well-being.

In other words, the virus absorbs the body’s ability to fight various kinds of diseases and infections, even in the smallest concentration, turning a simple cold into a real war for life.

The immunodeficiency virus has often become identified with AIDS. HIV positive status in an advanced form may well lead to AIDS. AIDS, as is known, is the result of the development of the last stage of a severe form of immunodeficiency. In fact, if a person is a carrier of the virus, this does not mean that he is sick with a disease such as AIDS, which is a much broader concept.

Connivance in the form of an advanced form of the immunodeficiency virus can be fatal for humans. There is no need to do this - ignore the risks, because not a single drug has yet been invented in the world that cures AIDS. This means only one thing - you need to do an infection test in time if there is the slightest suspicion of infection, because it may be wrong.

HIV – routes of infection and symptoms

The immunodeficiency virus is transmitted mainly through sexual contact with an infected person. Other routes of infection are known as through:

  • during blood transfusion in laboratory conditions (donor blood is always checked for infections, but small concentrations of the virus can be missed);
  • during contact between mother and child (during pregnancy, feeding or childbirth);
  • there may be infection from injections (needles), non-sterile devices and instruments (manicure accessories), and so on.

Symptoms of the primary manifestation of HIV infection appear as follows after just 6 weeks:

  • sore throat (aching, when swallowing, even outside meals);
  • state of chills;
  • muscle pain (not to be confused with physical activity);
  • if mouth ulcers do not heal for a long time;
  • maybe increased sweating during sleep;
  • partial memory loss;
  • a constant state of fatigue, but not as a result of overwork;
  • inflammation of the lymph nodes throughout the body;
  • pneumonia.
