Immunoassay for the in vitro quantitative determination of cortisol in human serum, and plasma. The determination of cortisol is used for the recognition and treatment of functional disorders of the adrenal gland. The electrochemiluminescence immunoassay "ECLIA" is intended for use on Elecsys and cobas e immunoassay analyzers. Cortisol II CalSet is used for calibrating the quantitative Elecsys Cortisol II assay on the Elecsys and cobas e immunoassay analyzers.

The Elecsys Cortisol II assay makes use of a competition test principle using a monoclonal antibody which is specifically directed against cortisol. Endogenous cortisol which has been liberated from binding proteins with danazol competes with exogenous cortisol derivative in the test which has been labeled with ruthenium complex for the binding sites on the biotinylated antibody. Results are determined via a calibration curve which is instrument specifically generated by 2point calibration and a master curve provided via reagent barcode. The reagent working solutions include: - rackpack (kit placed on instrument) . - Streptavidin coated microparticles, ş - Reagent 1 (Anti-cortisol-Ab~biotin) and ş - Reagent 2 (Cortisol-peptide~Ru(bpy)2+3). ş The Cortisol II CalSet is a lyophilized human serum with added cortisol in two concentration ranges.

Cortisol (also known as hydrocortisone, compound F) is the main glucocorticoid in humans and is produced in the zona fasciculata of the adrenal cortex. 90 % of the circulating cortisol are bound to corticoid binding globulin (CBG, Transcortin), ca. 7 % are bound to albumin and only 1-3 % are unbound. Only the latter part represents the active form of cortisol. The free cortisol is released in saliva and is excreted via the kidneys as a small part among the metabolites of cortisol. The level of free cortisol in blood regulates mainly its secretion in the adrenal cortex in a negative feedback mechanism via CRH (corticotropin releasing hormone) in the hypothalamic region and the ACTH in the pituitary gland, but it is also affected by different situations above all by stress. In humans, there is a physiological fluctuation of cortisol achieving the highest level in the morning and the lowest during the night. This fluctuation of cortisol plasma level is reflected in saliva normally with a peak in the first 90 minutes after waking up. The cortisol measurement is indicated in adrenal disorders. Due to the diurnal fluctuations of cortisol, a salivary sample collection is an easy method without the stress of repeated venipunctures. Test principle: Luminescence immunoassay based on the competition principle. An unknown amount of antigen present in the sample and a fixed amount of enzyme labelled antigen compete for the binding sites of the antibodies coated onto the wells. After incubation the wells are washed to stop the competition reaction. After addition of the luminescence substrate solution the intensity of the luminescence measured is inversely proportional to the amount of the antigen in the sample. Results of samples can be determined directly using the standard curve. Device composition: The device is available in two sizes, 96 tests and 960 tests. The device consists of an antibody coated 96 well Microtiter Plate, seven Standards (range 0.015 - 3.20 µg/dL, equivalent to 0.15 - 32 ng/mL calibrated to the NIST cortisol), two Controls, Enzyme Conjugate (Cortisol coupled to peroxidase), Chemiluminescence Reagent 1 and 2, 10x concentrated Wash Buffer, Adhesive Foils.
