*Biotin supplements can interfere with some LH and FSH assays; therefore, these supplements should be stopped at least 3 days before the blood test depending on how much biotin the patient is taking

Would you think 100-200mcg biotin to cause an issue in blood tests?

Sometimes all it takes is looking over the threads to find your answer.

1st thread in post #12 above.


It was laid out in post #2

*While the amount of usual dietary biotin intake is not expected to be high enough to affect these tests, biotin supplementation at doses greater than 1 mg per day can cause either falsely low or falsely high test results, depending on the analyte and platform used for testing.


*some multivitamin/mineral supplements have 1000+ mcg doses

*biotin supplements can easily have well over 1000+ mcg doses (300-10,000 mcg)

*many b-complex supplements can have 1000+ mcg doses
