The Access Cortisol assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of cortisol levels in human serum, plasma (heparin, EDTA) and urine using the Access Immunoassay Systems.

The Access Cortisol assay protocol file (APF) applies an incorrect calibration curve acceptance parameter at the S1 calibrator level that can lead to a high rate of calibration failures which can vary by reagent lot number. Calibration failure would lead to delay of measurement results reporting and potential injuries.
