Curious. is the half life of biotin in a persons blood taken in the range of 250mcg, 2 hours? see a lot of information on this topic, just want to ensure that lab tests are correct, as i waited 6 hours before testing. thx?

Contrary to internet buzz, there's probably little actual problem at all with biotin and the HIV antibody or AgAb tests. However, biotin's half life in the blood is 15 hours. (Two hours is the time to peak concentration.) If you want to avoid the theoretical issues, wait 3-4 half lives (2-3 days) before HIV testing.

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?
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?
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.?
Required to fast before the ELISA LAB test to avoid any biotin interference? Odd, as 0.25mg is fairly close to daily intake after 6 hours of dose. Im confident in my results, is a retest really needed? This comes after exposure of 7 years and 9 week?
Can less than 5mg biotin give a false negative on 4th generation eia lab test? And would 8-12 hours be enough time for it to get out your system?
