T4

Determination of hypothyroidism within the first few days of birth has been recognized as the single most important diagnostic test in neonates by the American Thyroid Association. The need for its early detection and treatment has resulted in the establishment of screening centres by federal and state health departments.

The Fortress Diagnostics Total Thyroxine (T4) is a colorimetric enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of T4 concentration in human serum or plasma.
