Is an HIV test conclusive at 60 days?
The median window period is 31 days (interquartile range 26 to 37 days). This indicates that half of all infections would be detected between 26 and 37 days after exposure. 99\% of HIV-infected individuals would be detectable within 57 days of exposure.
What does HIV screen 4th generation non reactive mean?
A non-reactive result from a fourth generation combination HIV Ab/Ag assay means that HIV-1 p24 antigens, HIV-1 antibodies, and HIV-2 antibodies were not detected in the sample processed.
When is a 4th generation HIV test conclusive?
If the test detects either the presence of HIV antibodies or antigens, it means the patient is most likely infected with HIV. This has to be confirmed with another ELISA test. We always do at least 2 tests before diagnosing a person as HIV +ve. Officially it is conclusive at 28 days post exposure.
What’s the difference between negative and non reactive?
Nonreactive vs. A nonreactive result means that the fluid sample did not contain HIV antigens or antibodies that the test aims to react to at the time of testing. It can mean a person has tested negative for HIV. However, if an individual has a nonreactive result, it does not necessarily mean they do not have HIV.
What does non-reactive result mean?
Nonreactive vs. A nonreactive result means that the fluid sample did not contain HIV antigens or antibodies that the test aims to react to at the time of testing. It can mean a person has tested negative for HIV.
What does non-reactive mean on STD test results?
Your STD test results may indicate “reactive,” “not-detected,” “non-reactive” or a reference range. Not detected and non-reactive mean the STD was not detected in your system. The reference range indicates whether the STD value is high enough to be considered positive; if not, it returns negative.
What does non reactive mean?
If you have been tested for HIV infection, you may be told that the result is ‘non-reactive’. This means that the test did not find any evidence of HIV infection.
Is non reactive the same as negative?

How long does it take to get tested for HIV?
Newer antigen/antibody combination tests (you might hear them called “fourth generation” tests) can find HIV in 99\% of people who are tested within 13 to 42 days of exposure. This test has become the standard HIV blood test in most labs.
Do I need to be re-tested for HIV?
There is a period between the time of getting HIV and the time that an HIV test can detect HIV infection. If you have engaged in risk behaviors for HIV during the month prior to your test, you should speak to your provider about your need to be re-tested for HIV.
How accurate is a western blot for HIV?
The results of both tests together are more than 99\% accurate. The tests used to confirm HIV infection are either the Western blot or indirect fluorescent antibody (IFA) test. If your screening test went to a laboratory, they can do this additional testing on the same blood sample.
