RNA PCR for HIV 1 can be done 10 days after the suspected exposure. This is one of the tests that detects presence of HIV virus very early.
Since the test looks for virus RNA, it is not dependent on production of antibodies by the body. The technique used in PCR test or Polymerase Chain Reaction is to extract and amplify the genetic material of the virus.
This test must be supplemented by HIV Duo Combo or Elisa for HIV at the end of 4 weeks.
HIV DUO COMBO
This is the fourth generation HIV test that looks for p24 antigen as well as antibodies for HIV 1 & 2.
The test is done after 4 weeks of suspected exposure and is very accurate. However, between day 14 and day 20 , the p24 antigen starts appearing in the blood. Hence , a negative result for HIV Duo Combo during this period gives a lot confidence. The PCR RNA test is done only if there is a high risk exposure or there are symptoms of being sero-positive. The advisable test for detection of HIV is antigen/ antibody screening test , done after 28 days of suspected exposure . For some people, PCR RNA test may be done to reduce anxiety , till 28 days are over and they are ready to take the antigen/antibody test.
For routine testing , the right test is antigen/ antibody test.
-:Note:-
Standard HIV tests look for antibodies your body develops in response to the virus, which can take weeks to appear. The RNA PCR test, on the other hand, detects the actual genetic material of the virus itself, offering results much sooner, as early as 10 days after potential exposure.
Yes, the RNA PCR test is considered the most accurate test for detecting HIV in the earliest stages. However, for definitive confirmation, it's often used alongside standard antigen/antibody tests later on.
If you believe you've had a high-risk exposure or are experiencing potential HIV symptoms, an RNA PCR test can provide valuable information for earlier diagnosis and potentially faster access to treatment.
Yes, just like standard HIV testing, RNA PCR tests are subject to strict confidentiality regulations. Your healthcare provider or testing center can provide more details about their specific privacy policies.
