FDA Status
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Setup Schedule
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.
