faqHow secure is this home HIV test?

The BioTechMed home test is compared safer than a standard pregnancy test. The reliability of the HIV test is sensitive at 100% (terms of recognition rate) and 99.86% specifity (compared to a pregnancy test is over 99.25%). Million pieces of this home HIV test are annually sold around the world. Our tests are primarily used by medical personnel such as laboratories, clinics and surgeries.

What are HIV and AIDS?

The human immunodeficiency virus (HIV), is a virus that causes the disease AIDS (Acquired Immune Deficiency Syndrome). Complete removal of HIV from the human body is not possible, since retroviruses are able to incorporate their genetic code into the genome of the host. Infection leads to a different length, usually several years of incubation period to AIDS, an incurable immune disease. In a minority (<5%) – the so-called Long Term Non-Progressor – the disease develops only after decades or perhaps never.

HI-viruses are divided into the world’s species occurring HIV-1 with the three groups M, N and O. The viruses of the most common group M are further subdivided into subtypes A through I. The subtype B is the most common in Western Europe and is found almost always in North America. In addition, there are the species HIV-2, which in turn is divided into subtypes. Of these, the most common subtypes A and B comes (in contrast to HIV-1) HIV-2 is still mainly in West Africa.

How is HIV virus transmitted?

The HIV virus is spread by contact with body fluids, blood, semen, vaginal secretions, and cerebrospinal fluid and breast milk. Potential entry points are fresh, still bleeding wounds and mucous membranes (eye, mouth, nose, vaginal and anal mucosa) and not enough horny, slightly vulnerable points of the outer skin (penis, inside of the foreskin). The most common routes of infection are to call the vaginal or anal intercourse without using condoms and sterile syringes in the use of intravenous drug use. Oral sex is, according to recent studies less infectious. Also here is apparently only the active partner at risk. An infection is especially possible if semen or menstrual blood gets to the oral mucosa. Gay men are a risk group because anal intercourse is common in this population rather than in the group of heterosexuals. The level of risk in sexual intercourse depends primarily on the virus concentration in semen, vaginal secretions and in the viral load in blood. This is immediately after infection before enough antibodies have been formed, particularly high, but then takes off first, and rises in the late stages of the disease again. As demonstrated in recent studies, the risk of infection for circumcised men is lower. Circumcision carries out the removal of the foreskin to a lower target for the virus. Blood transfusions are also a possible source of infection, although now in Germany by 1985, that routine examinations of blood donors has little meaning. But even here there is a risk, since the delay between infection can the donor and the detectability of HIV antibodies in the test up to three months. Therefore, all blood donations are tested for the presence of HIV by PCR in order to fill this diagnostic gap. The risk of infection of a child by a HIV-infected mother during pregnancy or during birth is estimated without treatment to 15 to 30 percent. With known HIV-infection of the mother can reduce the risk of transmission to the child by administering anti-retroviral drugs and the birth by caesarean section at about 2 percent. Virus transmission during breastfeeding is also possible.

Can I assume with a negative result, that I have not infected myself with HIV?

You can assume that you are HIV negative if you have performed the test, as described in the instructions and a clear line of control next to the “C” appears and no line next to the “1” or “2” forms (such as in the figure). In this case the test shows that no HIV antibodies were found in your blood at the time of test. Just like a test with a doctor or lab, you need no confirmation tests if the result is negative. However, you should expect a possible infection, when you are exposed to a risk less than three months. There is in fact, a possibility that not enough antibodies have formed in your body for detection. In this case, the test can show a (false) negative result. If for any reason whatsoever to doubt your negative test result, we advise you to repeat the test after three months and / or to consult a HIV information center.

The test can be used several times?

The HIV home test can be used only once.

Negative is positive and positive is negative?

A negative test result means no antibodies to HIV are in the body. A positive test result means the opposite: there are antibodies to HIV in the body and thus it is called HIV infection.

As long as the HIV self test last?

All HIV self-test is – if stored between 2 ° C – 30 ° C – stable for at least 3 months and a maximum of 24 months. The date by when the rapid test should be used is listed on the back of the package.

Does one need specific knowledge to complete the tests?

For the implementation of HIV self-test no med skills are needed. All for the implementation of the test necessary resources are part of the HIV test kit.

Why should someone make a HIV test?

Early diagnosis of HIV infection is really important. It is healthy to make the HIV test in the following cases:

* If you have had unprotected sex with a person infected with HIV is or if you are not sure whether the person is infected;
* If you want to have unprotected sex with your (fixed) sexual partner;
* If you want to be pregnant;
* If you come in contact with blood of another person;
* If you have injected drugs or anabolic steroids with an already used needle;
* If for any reason to worry about a possible HIV infection.

What about the reliability of HIV test?

The self-test is a very sensitive test. That means, when antibodies to HIV in the blood are present, the test recognizes them. With a negative result, you may assume you are not HIV infected.
However, there is a small chance that the test shows a positive result, even though you have not been infected with HIV. Therefore, we urge you in the event of a positive test result, to obtaining confirmation that again by a doctor.

What is p24 antigen?

The p24 antigen is a protein that is located in the inner viral envelope of HIV-1. So it is a part of the HI virus. It occurs approximately 15 days after infection in the blood, is thus it is earlier detectable than HIV-specific antibodies. A few weeks after HIV-antibody formation, however, p24 antigen disappears again from the peripheral blood. Until then, sufficient antibodies have formed, so that they can be detected by the HIV antibody test.
The advantage of the p24 antigen test is the reduction of the diagnostic window, which occurs in pure HIV antibody test.
HIV antibodies must be produced by the body only. The p24 antigen increased as part of HIV according to the HI virus.
An infection with HIV can be detected after 2 weeks by the antigen test.
