IVD DEVICE CALIBRATION IS MOST COMMONLY PERFORMED USING CALIBRATORS (REFERENCE MATERIALS) SPECIFICALLY INTENDED TO BE USED AS A STANDARD CURVE OR CUT-OFF POINT FOR AN ASSAY.

A CALIBRATOR HAS AN ASSIGNED VALUE THAT IS ESTABLISHED BY THE MANUFACTURER BY A REFERENCE METHOD. CALIBRATORS EXIST IN A VARIETY OF MATRICES SUCH AS SIMULATED AQUEOUS, SERUM, PLASMA OR OTHER TYPES OF SPECIMENS.

PRIMARY REFERENCE CALIBRATORS ARE HIGHLY PURIFIED CHEMICALS THAT CAN BE DIRECTLY WEIGHED OR MEASURED TO PRODUCE A SOLUTION OF KNOWN CONCENTRATION. ALTERNATIVELY, THEY MAY BE MORE COMPLEX BIOLOGICAL MATERIALS HAVING RECEIVED A VALUE ASSIGNMENT USING REFERENCE (STANDARD) METHODOLOGY. THEY ARE SUPPLIED WITH A CERTIFICATE OF ANALYSIS FOR EACH LOT (FOR EXAMPLE, STANDARD REFERENCE MATERIALS (SRMS) FROM THE U.S. NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST)).

THE PRIMARY CALIBRATOR “CALIBRATION SOLUTION FOR OSMOMAT 010 / 030 / auto” IS USED TO CALIBRATE THE OSMOMETERS “OSMOMAT 030” AND “OSMOMAT AUTO”, WHICH BOTH ARE FREEZING-POINT OSMOMETERS FOR USE IN CLINICAL CHEMISTRY. THE OSMOLALITY OF THE CALIBRATOR IS EQUAL TO THE OSMOLALITY OF BODY-FLUIDS (ISOTONIC SOLUTION), PROVIDING THAT THE OSMOMETER WILL BE CALIBRATED CORRECTLY FOR THE FLUIDS TO BE MEASURED FOR MEDICAL PURPOSES.

Indications for use as stated in the FDA summary.
