SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft document entitled “Testing for Biotin Interference in In Vitro Diagnostic Devices.” The draft guidance document provides FDA's recommendations on the testing for interference by biotin on the performance of IVDs. The draft guidance is intended to help device developers and clinicians understand how FDA recommends that biotin interference testing be performed and how the results of the testing should be communicated to end users, including clinical laboratories and clinicians. FDA also recommends that manufacturers of currently marketed devices consider these draft recommendations. The recommendations apply to IVDs, as well as devices that are licensed under section 351 of the Public Health Service Act (42 U.S.C. 262) and used in donor screening, that use biotin technology.

Biotin, also known as vitamin B7, is a water-soluble vitamin often found in multivitamins, prenatal vitamins, and dietary supplements marketed for hair, skin, and nail growth. FDA has become aware of potential biotin interference with IVDs that use biotin/avidin interactions as part of the device technology. Biotin in patient samples can cause falsely high or falsely low results, depending on the test.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on testing for biotin interference in in vitro diagnostic devices. It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. This guidance is not subject to Executive Order 12866.

II. Paperwork Reduction Act of 1995

The collections of information in 21 CFR part 809 have been approved under OMB control number 0901-0485.
