The accuracy of the HIV-ELISA test after 5 months

For accurate result analysis of HIV can be done several times. This is due to the fact that antibodies to the virus appear only after some time after infection. And making the test at the beginning, it will be difficult to determine the presence or absence in the body of these antibodies. Therefore, the exact answer after unprotected intercourse or use of infected medical instrument you get. That is why it is recommended to do tests a few times and after a certain time. This will help to more accurately examine whether infected or not.

What analysis is carried out and why

As the primary conduct test for HIV by ELISA. It does not show the presence of the virus and helps to detect antibodies to it. It gives the opportunity to prove that in the body exactly the virus is. This method is convenient because it is more accurate, even in the case that after viral loads not detected by PCR.

For accuracy of response and use of IFA. But since antibodies to the virus appear in different periods, then use it in different periods of time. For someone who this happens after 4 weeks and others 3 months or even later.

What is seronegative window

Seroconversion or a seronegative window called the period from the beginning of infection and its manifestations in the form of antibodies. This period everyone is individual and takes a different time. All will depend on the method of infection and the characteristics of the immune system. Accordingly, if transfused the infected blood, the seronegative window with a short period. And when injecting with an infected syringe that will last for a longer time.

But do not think that in the period of seroconversion, the person remains healthy. In fact, he is the source of infection and can infect other people. Therefore, it is important to exclude the possibility of getting infected blood into someone's body. You should not at this time to donate blood, engage in unprotected sex and get pregnant. Perhaps the virus will not be detected in the future, but such preventive measures will save you from worrying about friends and relatives.

Immunoenzyme analysis

ELISA one of the most popular research. He has a unique immunochemical reaction to determine what antigens bound by the antibodies. Often use a heterogeneous version of the analysis consists of 3 stages. In the early going, mixing of antigen and blood of the patient, and then make special antibodies and get the molecular chain of which it is possible to detect the viral protein. For this purpose, a Chromogen, which in the presence of the virus proteins will be painted. This would mean that the person is infected with HIV.

The high stability of its reagents, the simplicity of the method and high sensitivity have become the advantages of the method of IFA and widely distributed it for research. The ELISA method is constantly evolving and improving. Due to this fact, spend less time on research and get more accurate answers.

A second study with a positive result

If an HIV test gave a positive result, then be sure to conduct additional research. In some cases, the patient will not listen to the advice on the prep and it will turn out wrong. This can happen due to eating or alcohol before the test. Also of recent acute infectious disease may give erroneous results.

Additional research is often performed a method of immunoblot. He finds antibodies to individual HIV protein that gives reliable result. So with all the positive responses carried this additional study.

The investigation period for HIV

As the term seronegative window every different, the tests must be done after a certain amount of time. Doctors recommend to do the analysis three times: at 6 weeks, 3 months, 5 or 6 months. In some cases, to identify the virus sooner or later than this time. But this is not often the case. They can occur in the use of immunosuppressive drugsor in severe diseases of the immune system.

What determines the number of analyses

ELISA tests, which are used for determination of the virus used for many decades. Therefore, since the beginning of their use there were already some of the new generations, because the development of immune-enzyme analysis is not in place. And the number of tests will depend on the generation ELISA.

The first tests were not very sensitive, so the doctors recommended to increase the seronegative window of up to six months. Until that time, in the body there is a sufficient number of antibodies, which contributed to the detection of the virus.

But in the modern world there were four generations of ELISA tests and the latest ones are the most sensitive to the slightest concentration of antibodies. Accordingly, this helps to identify the disease much earlier than six months. Therefore, the reliability of HIV test after three months to be exact. In the new generation of tests other than the presence of antibodies that define the antigen P24. As it appears before antibodies are infected, the virus seen before.

Therefore, we can say that making the test is based on the 4th generation, you get a reliable result three months after infection. But as the doctors are insured and patients themselves do not want to worry about the time limit is extended for another few months. This is what is considered the optimal scheme of HIV testing.

Study partner for HIV

If there is any doubt that the person is infected, he passes the blood test. Some ask do I need to take the same examination a sex partner. Naturally, tests for both partners is a must. If one of them passed the test early by a few weeks or months, it's not terrible. The second partner can take them to the usual and customary order on terms.

This will help to know the exact result and not to worry. Be ashamed to pass these tests are not necessary, because the physicians do not distribute answers and is the place to be a medical mystery. If you do not want to reveal her surname, the analysis pass anonymously. This can be done in any AIDS-center. Will give the number where the patient come for an answer on a test.

While waiting for the response

Many people want to know how many days you can get your hands on the answers to the tests. On average, it takes about 5 days. If you want to know the answer faster, as the analysis choose Express test. With it, the answer can be obtained 15 minutes later on the same day.

In some cases, answers research get later, sometimes even after a couple of weeks. This is due to the laboratory performing the HIV test. So check in advance how much time you expect to receive a reply. You can also visit the website of the medical institution and learn reviews about it. There's also the website listed phone numbers which you can call and get answers to your questions.

How to behave during the seronegative window

During this period, people are constantly worried. It's natural. But not everyone knows how to behave and what to do. First of all, you need to understand that it is important to protect others even if you are sure that the results will be negative.

Therefore, it is recommended to adhere to some actions.

  1. You can not become a donor and donate blood.
  2. You should not have sex without protection.
  3. To monitor your blood does not impinge on others (in open wounds and scratches).
  4. Not to bring up pregnancy.
  5. Use disposable medical instruments.
  6. The tests for other infections that will help them to cure faster.

Such precaution will help to avoid problems and not to infect others. Better to be safe than continue to feel guilty when detected in the body of the virus. You will have to inform sexual partners about their disease, giving them the opportunity to learn about and to conduct tests.

If a virus is detected

With repeated positive analysis the person will know that his system detected a virus. But this does not mean that you need to close in the house, not to let anyone in and forget about normal life. Actually all completely wrong.

First of all, after the status is infected, you need to contact the AIDS Center. They will give you the necessary information on how to behave and what to do. Currently, medicines can cure HIV is not there, even though scientists are constantly working on it. But infected can live quite long and normal life.

To cope with the situation impossible. So you need to consult a doctor. He will prescribe drugs that can keep the virus under control and to suppress its reproduction. Though it does not remove the virus from the body, but is capable of long time to keep it on a small level.

The primary goal of treatment will increase CD4 lymphocytes T-cells, which play an important role in the immune system. They fight trapped in the body by bacteria, viruses, fungi and other microorganisms.

It is important to take prescribed medications consistently and not forget about them. If the patient notices that the prescription is not valid, it would appoint others with more appropriatecombination. With the appearance of opportunistic infections immediately carried out her treatment that will help save infected with HIV.

The psychological state of the infected

Many feel a victim of circumstances and helpless. Psychologically it's depressing and makes a person to panic. In this case, you can contact the support service people with HIV or call the helpline. This often forces them to reassess their fears and start a normal life.

When HIV infection is constantly felt anxiety for their friends and relatives. So it is advisable to gently tell them about the problem. At this time the patient will need support and if he doesn't get understanding from family and friends, it is always possible to communicate in the service of care for patients with HIV.

With the help of HIV tests the patient will get the correct results. And let will have to pass not one, but several tests over time, but it will give the opportunity to accurately understand the situation. If everything is fine and the virus was not detected, it is not necessary to think that the next time he will be spared. So you need to protect yourself, to protect themselves, to use new medical instruments. Health one and swap it in the case of a trivial error will not work. So we must remember how important it was to keep it and try to avoid such situations.
