: These results conclusively prove you do not have HIV. No need to test yet again.

Got a 4TH GEN Duo HIV test done at 4weeks and 6weeks, both came negative. Found some information on BIOTIN. Would my 5mg taken daily affect my results? Found other forums but in lower doses. Would 10mg affect? As these are doses found over the counte?

A member asked:

Tattoo got lymphamgitis. Im aware of HIV dying outside immediately on objects that arent hollow, so risk is low as I was the first person in 3 days. I got a ELISA hiv LAB test after 35 days & 45 days on 2.5mg biotin. BothNeg. Retest due to biotin?

A member asked:

Apologies if last HIV question was repeated; I didn't see anything regarding my test being conclusive in my reply, just the explanation of Biotin not interfering with lab tests. Can other medicines or coinfections like HEP C interfere with the test?

A member asked:

Hi, I had a negative HIV 1/2 AB lab test (3rd gen) at 100 days post one time encounter, I was told by my nurse practitioner that I need to test again at 6 months? Even though the man from my exposure was neg at 8 wks with a 4th gen test? Is this true?

A member asked:

Is a 4th Gen HIV Duo test prone to lab mishaps? For example, improper procedures which would cause a potential positive test to be read as negative? Ive taken numerous tests, last one being 40 days since exposure. Labs were done by well known lab?

As in my previous question. Having done a 4th gen HIV LAB test, at 4 and 6 weeks. Although on 5mg of biotin at 6weeks , can I consider my tests conclusive? Both negative. As these were LAB tests, unaware of window?

Abstained from biotin for approximately 65 hours before my HIV LAB 4th Gen at 12 week exposure. negative result. last dosage was 5mg, and am now reading that 1 week off biotin is needed to washout. Worried threshold is low. Can I move on?

Waited 60-65 hours after my biotin dose of 5000- 10000mcg. Did a LAB 4th GEN HIV test at 85 days exposure. Worried the assay biotin threshold is very low, as the labs wouldnt tell me. Do I need to wait up to a week off biotin and redo my test?

Just confirming, that 5000mcg of biotin would not require a washout period for hiv tests? Which I did for 65 hours. Does this apply to all assays doing the 4th Gen LAB tests, or are some assays more vulnerable to interference than others? Thx again.?

More details for questions will taking 600 mcg of biotin daily affect my hiv lab combo test? I read that it will cause false negative? Ive had multiple tests and all are a negative after vaginal sex After 4 months?
