Hello, My name is***** am a board certified physician, and would be happy to help you with your health concern. Please give me a few minutes to read, and respond to your question.

Thanks for your question. The current guidelines indicate that their are 4 indications for PCR testing:

1) Newborn who has potentially contracted HIV from the mother during delivery

2) Person who has indeterminate antibody tests

3) Blood that has been donated to a blood bank

4) If a doctor thinks a patient has HIV, but the antibody test is negative

Please let me know if I can answer any additional questions for you.

Should I request a PCR from my doctor to confirm negative antibody/antigen results?

You can certainly do that if it will give yo peace of mind. The fact that you have had multiple negative tests indicates that you most likely don't have HIV.
