How does risk determine the window period for the tests. If the situation is high risk, it is recommended that test be repeated at 3 months and 6 months. How does seroconversion vary based on risk. I asked this to a nurse in health clinic. She said that the reason they recommend repeated tests at 3 and 6 months is to bring the person back in the clinic so that some counselling can be done not because there may be delayed seroconversion, but still recommend 3 month for conclusive resulsts.Any comments?
When I asked my question on doctor's forum, Dr. Cummings said no further testin was required beyond 8 weeks. It is conclusive. I believe Dr. HHH and Dr. Hook have same opinion. Now this 3 month comment from the nurse is again creating anxiety.
it is highly unlikely that a result will change after 8 weeks...but the guideline set by the manufacturers of the tests, the cdc, and the fda...still states that a test is CONCLUSIVE at 3 months post exposure. (regardless of risk)
In an adult, a positive HIV antibody test result means that the person is infected, a person with a negative or inconclusive result may be in the “window for 4 to 6 weeks but occasionally up to 3 months after HIV exposure. Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results
