Intended Use For the quantitative determination of the Total Thyroxine (T4) concentration in human serum. Teco Diagnostics TEST: TOTAL THYROXINE MICROTITER (T4W-96) NUMBER OF TESTS: 96 TESTS FORMAT: LIQUID Principle Anti-T4 antibody is coated on microtiter wells. Patient serum and T4 conjugated with horseradish peroxidase are added to the microtiter wells. During incubation, T4 and conjugated T4 compete for the limited binding sites on the anti-T4 antibody. The wells are washed and a color indicator is added, followed by further incubation. The color development is stopped and the absorbance is measured spectrophotometrically at 450 nm. The intensity of the color formed is proportional to the amount of enzyme present and is inversely related to the amount of unlabeled T4 in the sample. METHOD: COLORIMETRIC TESTING PROCEDURE: MANUAL STORAGE TEMPERATURE: 2-8°C WAVELENGTH: 450 NM SENSITIVITY: 0.4 jug/dl EXPECTED VALUES: 4.8-12.0 ug/dl EXPECTED SHELF LIFE: MIN 20 MTH CONTACT US: TECO DIAGNOSTICS 1268 N.
