Thyroglobulin and Thyroglobulin Antibody
General Information
Lab Name
Thyroglobulin Panel
Lab Code
THGLBN
Epic Name
Thyroglobulin and Antibody Panel (Thyroid Cancer Recurrence)
Description
Note: Thyroglobulin antibodies can interfere with measurement of thyroglobulin. Consequently, this panel includes a screen for these antibodies. The mass spectrometry (LCMS) method does not have this interference. TG by LCMS will be added reflexively if the antibody result is positive or indeterminate and the TG by immunoassay is ≤1.00 ng/mL. In these cases, the TG by immunoassay will be credited. See TGFNA for fluid Thyroglobulin testing.
Synonyms
LCMS, TG, TG Tumor Marker, TGLCMS, Thyroglobulin Recovery, Thyroglobulin Tumor Marker

Ref. Range Notes
Patient results determined by assays using different manufacturers, instruments, or methods may not be comparable.
Interferences and Limitations
Biotin supplements can cause falsely low values. See Limitations of Laboratory Testing for details.
