6 Week Hiv Test
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
If positive: If the test is positive, it is conclusive. In a small number of infected people it may take longer for the test to become positive. Blood Banks defer potential donors for one year from the time of exposure. For all practical purposes if the nucleic acid test is negative at 6 months after exposure the person is free of HIV.

According to WHO, 6 weeks HIV test is conclusive (unless I miss understood it) then why CDC recommends 3 to 6 months for conclusive results?
The "Window Period": Window period is the time it takes lymphocytes to develop antibodies to an antigen. This is usually 4-6 weeks but can be as long as 3 months. By 3 months after exposure...97% of people will have antibodies to antigen. In rarer instances it may take up to 6 months to develop antibodies. After 6 months..99% of people exposed will have antibodies to viral antigens. Therefore the 3 to 6 months!!! ...Read more
6 week HIV RNA negative. Anti-hcv negative <0.1 8 week HIV negative < HCV PCR negative. 10 week HIV negative HCV 0.2 negative. ? Remain negative?
Likely yes: I think your in the clear for hep c. While its great that your negative HIV RNA pcr the typical protocol is time 0, 3 and 6 months after that. Now having said that...I have a large primarily HIV practice in south florida and its rare in my opinion not to have seroconverted and developed high titres of HIV virus at this point. But you still need further follow up. ...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
Negative blood test 15 negative pregnancy test throughout 6 months 1 period in 6 months no symptoms no sec for 6 months am i 22 weeks pregnant?
Probably not: It is always possible for there to be false negative test results, but so unlikely for so many tests to be falsely negative. Many things can cause irregular/skipped periods. Sonogram and hormone level testing with doctor visit should be able to help give you an answer. ...Read moreSee 1 more doctor answer
Hiv rna test result undetected after unprotected blowjob at day17. Test range 40 to 10mil. Is it conclusive?regular hiv test neg at 15 days. Hiv?
No risk: HIV is rarely transmitted by oral sex. If you were the receiver of the BJ, you can be sure you weren't infected: there are few if any proved cases of oral to genital HIV transmission. Most experts would have recommended against an RNA test in this situation, but the negative result is additional strong evidence you weren't infected. The "regular" test is only slightly reassuring, 4-6 wk minimum. ...Read more
Window periods hiv test. I had 4 test hiv combo after 94 days negative.But my country state window period 6 month. Malaysia. ?
4 weeks. Believe it.: Only a few companies make most of the HIV tests used worldwide. The window period for the combo test (also called duo or 4th generation test) is the same everywhere, 4 weeks. That a particular health department or agency takes a conservative stance and promotes longer periods is a decision based on legalities, politics, and social context. I can't say why some agency in Malaysia says 6 months. ...Read more
Depends: There are two major tests for HIV - one is measuring the antibody response to the virus present and that can take about this time to become detectable in the blood, so there is a chance the antibody test may still be negative if the time of exposure is not certain. Another test would measure the actual virus in the blood (viral load). This test becomes + very early in the disease, so go for this 1. ...Read more
Not necessarily.: Officially - the window period for HIV seroconversion (converting from a negative antibody to positive antibody test) can be up to 3 months. Most seroconversion should happen by 1 month but some can take up to three month. One option is to take a more sensitive test such as a HIV RNA (or viral load) test - this should pick up an infection after 2 weeks and would be conclusive at 6 weeks. ...Read moreSee 1 more doctor answer

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
