Should I repeat an HIV test if the tridot test is negative?

Question

Hello doctor,

HIV (Human Immunodeficiency Virus) 1 and 2 are nonreactive in the tri-dot test done after 28 days of exposure. Should I repeat the test for confirmation?

Kindly help.

Answer 1

Hello,

Welcome to icliniq.com.

Tri-dot is a third-generation test for HIV (human immunodeficiency virus). HIV infection has a window period of one to three months, during which these test results may be false-negative. According to WHO (World Health Organization), all the test results are considered conclusive 12 weeks after the last exposure. However, fourth-generation HIV tests are considered accurate one month after the last exposure. Hence, you can repeat the tri-dot after three months or go for a fourth-generation combo test one month after the last exposure to confirm the result.

I hope this helps.

Hello,

The test is almost 99 percent accurate by two weeks. However, as per WHO guidelines, we advise retesting after a baseline test.
