Test Includes

All specimens are initially assayed for TgAb by the highly sensitive Beckman Coulter IMA. Samples with TgAb below the detectable limit are assayed for Tg by a sensitive second-generation IMA (Beckman Coulter) with a relatively rapid turnaround time. Specimens with any measurable levels of TgAb are assayed by an RIA method performed at Endocrine Sciences, Calabasas Hills, Calif. This RIA is resistant to interference by TgAb but has a longer turnaround time of five to seven days.  

Methodology

Immunometric assay (IMA) and radioimmunoassay (RIA)
