Done HIV DNA RT PCR Test After 4.5 Days Of Exposure. How Reliable Is It?
Thanks for writing in.
I understand your concern.
I advise you to relax as the HIV PCR is very much accurate and almost 100% reliable at 28 days.
It can detect almost less than 50 viral copies when present in blood.
As you know all the test have window period. Antibody based test like ELISA has more window period upto 3 months.
You can retest at 28 days for ELISA , western blot or RT PCR.
Also you can retest for RPR test for syphilis.
Also I would like to know -
Do you have any symptoms related to genitals?
What was the exposure like?(high risk or low risk)
Also please be calm as DNA PCR is
The DNA PCR is the absolute most sensitive test for HIV. In terms of measurement capacity, it can detect as little as 10 copies of proviral DNA per milliliter of whole blood.
The sensitivity of the test is 100% and is very accurate test. You can rely on it especially if the test is done after 2 weeks of exposure.
Hope this helps.
Regards.
After going through the description I feel it is a low risk episode.
As discussed earlier there is nothing to worried as the DNA PCR is negative.
Re testing of ELISA needs to be done at 4 weeks.
Hope this helps.
Wishing you good health.
