A member asked:

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.?

Half life of biotin is only 2 hours so if you abstain biotin for almost 3 days then you should not worry about any interaction with the results of 4th generation HIV test. Take care.
