EVALUATION DATA
Calibrated to major competitors and in house standards. The co-efficient of variation of PATHOZYME PROGESTERONE is less than or equal to 10% In an evaluation between the Omega Pathozyme Progesterone kit and the DRG BIOC Kit for samples with levels between 0.35 ng/ml and 73.83 ng/ml the following data was generated.
These kits were shown to give good correlation.
