Set up: Sat-Thurs; Report available: 3-5 days
Reference Range
Athyrotic | <0.4 ng/mL |
Clinical Significance
Measurement of thyroglobulin (Tg) is useful in the detection of residual or recurrent thyroid cancer. Many individuals develop auto-antibodies to Tg (Tg Ab) and the presence of Tg Ab interferes with the measurement of immunoassay Tg. The LC/MS/MS assay will provide quantitative measurement of Tg in the presence of Tg Ab.
