Does biotin affect PSA levels?

Circulating biotin levels greater than 20 ng/mL are reported to exhibit interference in high sensitivity troponin T (hs-TnT), thyroid stimulating hormone (TSH), and in prostate specific antigen (PSA) among other assays when using our Cobas® 6000 immunoassay analyzer (Roche Diagnostics, IN, USA).

Is 10000 mcg biotin too much?

Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date. Reassuringly, even “mega doses” of 300,000 mcg found no side effects in neurological research.

What should I know about biotin technology and interference?

Contact the FDA if you have any questions about biotin technology and interference.

For example, biotin is used in hormone tests and tests for markers of cardiac health like troponin.
