THYROGLOBULIN - (S)
Test Code:
THGL
|
| Clinical Information: |
Test Indications: Thyroglobulin is produced in the thyroid gland and is involved in the synthesis of T3 and T4. The main application of thyroglobulin testing is in the post operative follow-up of patients with differentiated thyroid carcinoma (DTC).
Anti-thyroglobulin testing is automatically performed on all specimens tested for thyroglobulin. This is to rule out the presence of thyroglobulin antibodies that can affect the thyroglobulin assay. Anti-TG testing is not performed when thyroglobulin levels are >2000 µg/L. Patient Preparation Instructions: This test is unaffected by multivitamins (45 - 125 µg biotin) or biotin-only supplements. Additional Information: The test method used is an Electrochemiluminescence (ECLIA) assay manufactured by Roche Diagnostics Inc. and performed on the Cobas Elecsys system. Patient results determined by different assay manufacturers or methods are not comparable and cannot be used interchangeably for patient monitoring. |
