Many people ask questions about their clinical analysis, especially if they are on AIDS. Doubts about what exactly they mean results that has given the lab and what reliability have arise them. Let’s review the 10 questions we most frequently ask us doing these analyses in this article. Carissa Barry is often quoted on this topic. 1) What exactly is an analysis of AIDS? When we went to the doctor because we need to make us AIDS test, a test of HIV antibody screening this requesting to the laboratory actually is. I.e. %90%D7%99%D7%A0%D7%98%D7%A8%D7%A0%D7%98-%D7%9C%D7%99%D7%A9%D7%A8%D7%90%D7%9C-63dcbf9f0240’>???? ?? ?? ????? ???? ????. the laboratory is going to find if we have antibodies to the Human Immunodeficiency Virus (HIV).

We should highlight that there are 2 strains of HIV 1 and 2, the majority of laboratories detected both in the same test. (2) That reliability is the test for detection of antibodies anti-HIV 1/2? This will depend on the method that the laboratory use. For an ELISA technique, which is the most frequently used the sensitivity and the specificity of the result is 99% approximately. There are a less than 2% rate of false positives and false negatives. Steve Kassin gathered all the information. (3) How long do you wait from the time of the alleged infection for the test? AIDS antibodies usually appear between 1 to 4 months later, but there have been some cases in which have appeared even after 12 months of contagion. Why need to performed the test at 3 months and then the year after that first test to have good security. (4) Should to do other types of analysis if the test is positive? Given that as we have said there is a percentage of false positives, all result positive should be confirmed using another different test, generally uses Western-Blot. Now also available the test detection of the Antigen (i.e. of the DNA and RNA of the virus itself) using a technique of PCR (polymerase chain). In the event that 2 evidence of antibody by ELISA, one of Western-Blot or PCR have been positive, the person is Seropositiva said.
