PRINCIPLES OF THE METHOD
A fixed amount of 125I labelled steroid competes with the steroid to be measured present in the sample or in the calibrator for a fixed amount of antibody sites immobilized on the wall of a polystyrene tube. Neither extraction nor chromatography is required because of the high specificity of the coated antibodies. After 3 hours incubation at 37°C, an aspiration step terminates the competition reaction. The tubes are then washed with 3 ml of washing solution and aspirated. A calibration curve is plotted and the 17OH concentrations of the samples are determined by dose interpolation from the calibration curve.
The above test kits measures the total (unconjugated) 17-OH-progesterone in human serum and plasma. There is also a method available for the measurement of free 17-OH-progesterone in saliva. The metabolic activity of any steroid is just represented by the free hormone fraction which represents less than 5% of the total. The non-invasive sampling of saliva samples offers another advantage of salivary testing. Demeditec is offering such a testkit in ELISA format with the catalogue number DESLV3140.
