How accurate is a negative home OraQuick hiv test at detecting later stage hiv or aids?

Fairly good.: If the test is performed exactly as instructed, a false negative test is very unlikely in advanced HIV/AIDS. (A false negative is a negative test in a person who, in fact, does have the condition being tested.) However, it's also unlikely that a person with late stage HIV/AIDS wouldn't already have sought medical care since they would be quite symptomatic by then. ...Read more

The new 4th generation antigen/antibody tests will eliminate this problem. ...Read more
