Manufacturer Narrative

One patient sample was returned for investigation.The investigation identified an interfering factor against the streptavidin component of the reagent in the sample.The interfering factor is documented in product labeling which states: interference in the method sheets of all applicable products: in rare cases, interference due to extremely high titers of antibodies to analyte-specific antibodies, streptavidin or ruthenium can occur.These effects are minimized by suitable test design.
