Cortisol, RIA CT, 96 tests

Radioimmunoassay for the Quantitative Determination of Cortisol in Human serum, plasma and urine.

Since the concentrations of 125I - Cortisol and coated antibodies are constant, the advancing state of the equation depends on the concentration of Cortisol.

The amount of 125I - Cortisol bound to the coated tube is inversely proportional to the concentration of Cortisol in the sample.

Following the incubation, the tube is aspirated to remove excess unbound labelled T. Patient sample concentrations are read from a calibration curve.
