Are HIV tests conclusive after 3 months of exposure?
Patient's Query
Hello doctor,
Following a low-risk exposure to HIV, I tested negative with the following tests. HIV duo ultra at 21 days, HIV combo at 23 days, HIV duo ultra at 29 days, HIV combo at 35 days, HIV duo ultra at 42 days, and HIV combo at 54 days. A chemiluminescence test, I cannot remember the name, but it was done at 61 days.
They were all laboratory tests with blood drawn from veins, and the Ab or Ag tests all came back negative. I heard that CDC now considers a six-plus-week ab/ag test fully conclusive. Are these tests conclusive, or would I still need to test at three months?
Please suggest.
Hello,
Welcome to icliniq.com.
I have read your query thoroughly, and there is no need for a repeat for HIV (human immunodeficiency virus). It is recommended to test for HIV with a combo test, which means a chemiluminescence test, after six weeks of exposure.
Usually, after six weeks, almost all patients can rule out HIV with a combo test or fourth-generation ELISA (enzyme-linked immunoassay). But still, it is advisable to check again after three months of exposure. The Western blot test is recommended if you want to rule it out early.
I hope I have answered your question.
Let me know if I can assist you further.
Regards.
