DUO at 27 days

Hi, I miss calculated the days since my risk, which was low risk, and took the test at 27 days DUO that is. Do I need to re-test if it was negative, I could kick myself for being so silly and over eager to get it sorted out. Trouble is, I have a bad cold, and had it on and the day before the test, if this was a symptom of ARS would the test have been positive. To tell the truth I just wanna forget the whole episode, so any advice to help me do it is apprecitaed, be that to re-test or not. Thanks

I see on the Doctor's forum where the Dr. said that some physicians will do a DUO test or a PCR test if the risk was considered "high risk".   This does not see to suit your original situation.

The DUO test is an HIV test that looks for antibodies for HIV-1 and HIV-2 and also looks for evidence of the p24 protein which is on the surface of the HIV virus particle.

The advantage of testing for p24 is that this indicator of HIV infection can be detected earlier than with tests that only looked for HIV antibodies. This can be any time from 4 weeks after exposure.



This study reports that the test was 100% accurate if you get a negative result, and 94% accurate if you get a positive result. As with other types of HIV tests, a positive result need to be confirmed with a different test.

A negative result would only need to be confirmed with a second test if you were exposed less than 3 months ago. As with all antibody tests, the results relate to your HIV status 3 months before the test.

A case report of the DUO test taking more than 4 week to generate a positive result, emphasises the importance of confirming a negative result from any test used less than three months after the exposure risk, with a follow up test 3 months later.

The DUO test has no particluar advantages over other routine test when infection is unlikely to have been recent, because p24 is only detected for a short time after infection, and before HIV antibodies can be detected.

I thought the DUO was 99.8% at 28 days? So why would you need a 3 month test if it was negative at 28 days? I was asking anyone if they know what the accuracy is at 27 days instead of the 28. DUO which is p24 antigen and antibodies together.
