Description
Access Total T4 Reagent Kit, Part Number: 33800, Lot Numbers (s): All reagent pack lots The Access Total T4 assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of total thyroxine (T4) levels in human serum and plasma using the Access Immunoassay Systems. Total T4 assay results are used for diagnosis and confirmation of thyroid disorders such as hyper- and hypothyroidism.
The recall was initiated because the concentration of total T4 in samples from pregnant women is erroneously low (20%) when measured using the Access Total T4 assay. Erroneously low results which are actually high (outside of the normal reference range) could mask hyperthyroidism. Failure to diagnose or treat hyperthyroid disease associated with pregnancy could result in serious, permanent harm
