How long for a retest for hepatitis a, b, c, syphillis, hiv? Thanks

Text books. I am sorry but we only have four hundred characters. What do you mean retest? When was your exposure? The test for each these infections have a different time frame on when they would be valid. Perhaps you need to spend a few minutes reading online about each of these common stds and the bring us specific questions that we can answer in this forum.
