Methodology

Immunometric assay (IMA and radioimmunoassay (RIA); Anti-Tg: Beckman Coulter immunometric assay; Tg IMA: Beckman Coulter immunometric assay; Tg RIA: Lab-developed radioimmunoassay LabCorp uses a dual Tg test strategy in an effort to minimize the potential effect of TgAb interference on Tg analysis. 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.
