The Access TSH (3rd IS) assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative etermdination of human thyroid-stimulating hormone (thyrotropin, TSH, hTSH) levels in human serum and plasma using the Access Immunoassay Systems. Measurements of thyroid stimulating hormone produced by the anterior pituitary are used in the diagnosis of thyroid or pituitary disorders. This assay is capable of providing 3rd generation TSH results. The DxI 9000 Access Immunoassay Analyzer is an in vitro diagnostic device used for the quantitative, semi-quantitative, or qualitative determination of various analyte concentrations found in human body fluids.

Beckman Coulter has identified that Access Total T4 Calibrator lots (PN 33805) exhibit a negative bias on DxI 600/800 instruments, with slopes outside product specifications. A false low patient result could cause a patient to undergo unnecessary additional diagnostic testing. A patient may be treated for a disorder not present or receive delayed treatment for hyperthyroidism. For a pregnant patient being monitored for thyroid hormone supplementation, incorrect treatment or dose may be used. A delayed patient results could cause repeat blood draw with associated complications.
