Merck, T-113-1ML, Thyroglobulin solution

General description
Thyroglobulin (Tg) is a dimeric protein used by the thyroid gland to produce the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroglobulin levels are measured to evaluate the effectiveness of treatment for differentiated thyroid carcinoma (DTC) and to monitor for DTC recurrence. Thyroglobulin testing may also be performed to help determine the cause of hyperthyroidism and to monitor the treatment effectiveness of Graves′ disease. This standard confirms to the criteria of a Primary Standard and a Certified Reference Material, as defined by the ISO guidelines. It is traceable to both the SI and higher-order standards through a continuous series of precise comparisons. The diluent used is SigMatrix (2% recombinant human albumin in phosphate buffered saline). Use a minimum of 10 µL sample for quantitative applications.
