How long does biotin stay in the blood?

Biotin’s half-life is approximately 2 hours, so abstinence for 8 hours may be sufficient to minimize interference. However, it is highly recommended that patients taking massive biotin doses abstain for 72 hours before having blood specimens drawn for laboratory tests.

How much B7 should you take a day?

Requirements. There is no recommended daily allowance (RDA) for biotin, because there is insufficient evidence to establish one. However, the Institute of Medicine (IOM) suggests an adequate intake (AI) 30 micrograms (mcg) a day for adults aged 19 years and over.

The B7 Vitamin deficiency testing (Biotin test) may be used to determine Vitamin B7 deficiency. Vitamin B7 or Biotin is needed for cell growth, metabolism of fats and amino acids and production of fatty acids.

Does biotin mess with hormones?

Most of the published research on biotin interference covers hormone tests, such as parathyroid hormone (PTH), thyroid stimulating hormone (TSH), T4 and T3 tests, as well as tests for troponin. However, because biotin is used in so many immunoassays, scientists say it could interfere with many others.
