Biotin Interference in Clinical Immunoassays: An Overview

From the 2020 Joint Annual Meeting (July 1, 2020)
Presented by Minh Kosfeld, PhD, MLT(ASCP)CM
Biotin is a B vitamin that is a cofactor in a variety of metabolic reactions. It is a component of the capture antibody complex in some immunoassays, and intake of Biotin megadoses can interfere with these assays. This presentation addresses the mechanism of interference and ways to mitigate the effect.

At the conclusion of this presentation, participants will be able to:

  1. Explain the mechanism of biotin interference in the commonly used diagnostic immunoassays.
  2. Identify common laboratory tests affected by biotin interference and provide examples of its impact on clinical diagnoses.
  3. Summarize current approaches to identify and minimize the effects of biotin interference.
