简要总结
Inaccuracy of laboratory medicine diagnostic tests may be associated with ingestion of over-the-counter biotin supplements.
详细描述
Study group 1) Due to a lack of systematic studies, little is known about how performance of specific biotinylated immunoassays is associated with biotin ingestion at doses common in over-the-counter supplements (10 mg/d) in healthy adults and subjects with thyroid hormone supplementation. Therefore, this study was designed to assess the association of short-term biotin ingestion for 10 days with performance of various analytes based on Roche, Abbott and Siemens assays.
Study group 2) Due to a lack of systematic studies, little is known about how performance of specific biotinylated immunoassays is associated with biotin ingestion at doses common in multivitamin supplements (biotin = 50 µg/d) in healthy adults. Therefore, this study was designed to assess the association of short-term biotin ingestion for 20 days with performance of various analytes based on Roche, Abbott and Siemens assays.

研究组 & 干预措施
Healthy cohort - low dose
Apparently healthy subjects, who take 50 µg/d of biotin at the same time each morning for 20 days. Blood draw for biobanking will be collected at baseline prior to starting biotin (day 1), after 10 days of biotin supplementation (day 10), after 20 days of biotin supplementation (day 20), and 10 days after participants stopped taking biotin (day 30).
干预措施: Biotin (Dietary Supplement)
Hypothyroid cohort
Subjects under thyroid medication, who take 10 mg/d of biotin at the same time each morning for 10 days. Blood draw for biobanking will be collected at baseline prior to starting biotin (day 1), after 10 days of biotin supplementation (day 10), and 10 days after participants stopped taking biotin (day 20).
干预措施: Biotin (Dietary Supplement)
Healthy cohort - high dose
Apparently healthy subjects, who take 10 mg/d of biotin at the same time each morning for 10 days. Blood draw for biobanking will be collected at baseline prior to starting biotin (day 1), after 10 days of biotin supplementation (day 10), and 10 days after participants stopped taking biotin (day 20).
干预措施: Biotin (Dietary Supplement)

时间窗: 20 days (high-dose groups) and 30 days (low-dose group)
The study aims to assess the performance of specific biotinylated immunoassays after 10 days of ingesting 10 mg/d of biotin (high-dose), or 50 µg/d of biotin (low-dose). Control measurements will be performed at baseline (before biotin intake), and 10 days after last biotin intake.
