Description

For routine Thyroglobulin testing see Lab Mne: THGLBN

This assay [THYRG] should be reserved for patients with autoantibodies or in clinical situations when traditional immunoassay results are suspect.

The concentration of thyroglobulin is determined by trypsin digestion and immunoaffinity peptdide enrichment followed by liquid chromatrography-tandem mass spectrometry. The reportable range is 0.15 to 10.00 ng/mL with imprecision between 3.0 and 9.0 %CV.
