Hiv Test Paper
Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more
I did 4th Generation HIV test after around 4,5,6,7,8,9,10,11,12,14,15 weeks of an exposure.
Is this 100% conclusive? can i get back safely to my wife
Sero-conversion: The whole concept of delayed sero-conversion dates back to old & sloppy tests. PCR testing now will show virus in the blood with or without antibodies. If you need to cling to the old adages...at 6 months..99.99% of the population will have developed antibodies after an exposure..thus the 6 month window. I believe a colleague of mine Lyssette Cardona, MD is in Dubai..she's one of the best!! ...Read more
I had HIV test today and in paper they wrote hiv1 and hiv2, what are these tests?They will give me results in 15 days, why?
HIV: The new 4th generation testing for antibodies is incredibly accurate by 10-12 weeks, but there is always that rare individual who has delayed antibody response and may not be positive for up to 6 mos. If one wishes to be certain they can undergo pcr for hiv-rna ($$$) which is definitive within 2-4 weeks or earlier. ...Read more
HIV: Depending upon the test employed it may be very accurate, but at one week after exposure you may not have yet developed antibodies, and if a combined test including p24 antigen is used the levels may not yet be high enough to detect. You should be retested at one, three and some would say again at 6 mos. ...Read more
HIV: It is highly likely if you are negative at 14 weeks that you will remain so. There are, however, rare individuals who may turn positive later on and most will suggest testing up until 6 mos and some until one year. ...Read more
Not for diagnosis: It's very useful for monitoring the response to hiv, and it's accurate to diagnose or rule out acute HIV infection in someone with symptoms, but for simply diagnosing HIV infection, the HIV serology (antibody test) is better. That's because people who aren't infected can have false positive RNA tests, and people who are positive can have false negative RNA test. ...Read more
There are several ways to detect the HIV virus. The first is by antibodies. This includes eia (enzyme immuno assay). The rapid HIV tests are these types. The second way detects proteins on the viral coat (western blot). This is a gel plate electrophoresis. Thirdly there is pcr (polymerase chain reaction). This detects and amplifies dna allowing a viral ...Read more
Human immunodeficiency virus (HIV) is a lentivirus (a member of the retrovirus family) that causes acquired immunodeficiency syndrome (aids),  a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections ...Read more
