Darmstadt, Germany — Merck, a leading science and technology company, today introduced the first Certified Spiking Solution® of intact, heavy labeled Thyroglobulin in SigMatrix®, a synthetic surrogate serum. The matrix-based reference material is suitable as an internal standard for the quantification of Tg levels to ensure accurate, identifiable and quantifiable clinical diagnostic testing.

Merck’s solution-based product is the first endogenous protein biomarker of the extensive Cerilliant® portfolio. Measurement of patient Thyroglobulin levels is primarily performed to monitor differentiated thyroid carcinoma recurrence following therapy.1 Quantification of Thyroglobulin levels is also useful in determining the cause of hyperthyroidism and for monitoring treatment effectiv
