In competitive assays, useful for small molecules such as thyroxine (T4), there is an inverse association between analyte concentration and assay signal; biotin interference ... May 01, 2018 · A manufacturer-issued medical device safety alert released in May 2017 identified 4 immunoassays on the Access and DxI platforms that use biotin–streptavidin as susceptible to interference at biotin concentrations of ≥100 ng/mL ( 26 ). The 4 assays were free T 4, GI Monitor, Thyroglobulin, and Total T 3. Biotin interference can produce either falsely high or low results, depending on immunoassay format. In general, biotin causes falsely high results in competitive immunoassays and falsely low results in immunometric immunoassays. The degree of interference may vary by immunoassay manufacturer. A letter to the editor published in the August 18 ... The objective of this study was to evaluate the degree of biotin interference on a streptavidin-biotin chemistry-based HIV immunoassay.

Apr 29, 2020 · been the foundation of immunoassay design, and proven to help ensure highly sensitive, specific, accurate and stable immunoassays.12 Ortho assays may use designs in one of two architectures: pre-bound (not susceptible to biotin interference) and non-pre-bound (may be susceptible to biotin interference).
