- HIVinfection and AIDS that develops from it are undoubtably the most severe STDs of our time.
- The infection can transfer by:
- Unprotected sexual relationship
- Infected blood or blood product
- Transfer form mother to child: infection in the womb, during labor and nursing
- By intravenous drug use
- Via unsterilized devices.
The examination of possible HIV infection consists of two steps:
- Antibody- examination: we examine whether the given blood sample contains antibodies that the body produces to fight HIV infections. These tests are developed to be ultra-sensitive so that no mistake ( the positive test is regarded as negative) can be made. The result is therefore influenced by many factors and the fact that there are antibodies in the blood sample doesn’t at all mean that there is an HIV infection.
Positive results in the first step mean that there is only a suspicion of HIV infection. Because of this, specialists use the word „reactive” instead of „positive” in the first stages of examination.
- Justification procedure: we look for viral components, signs that point to HIV infection. If, during the second step of the examination, the suspicion in the first step is proven positive by other factors, the lab will give out the diagnosis of HIV- positive.
