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.

A FREEZING-POINT OR CRYOSCOPIC OSMOMETER IS A DEVICE TO MEASURE THE NUMBER OF MOLECULES OR IONS DISSOLVED IN A FLUID, IN THIS CASE, WATER. THE PHYSICAL EFFECT THE MEASUREMENT IS BASED ON IS THAT DISSOLVED SUBSTANCES IN WATER DEPRESS THE FREEZING POINT OF THE SOLUTION. THIS DEPRESSION IN THE FREEZING TEMPERATURE ITSELF, MEASURED EXACTLY, GIVES AN EXACT MEASURE FOR HOW MANY MOLECULES OR IONS ARE DISSOLVED IN THE AQUEQUS CALIBRATOR OR SPECIMEN. THIS EFFECT IS PHYSICAL, WHICH MEANS THAT THE CHEMICAL PROPERTIES OF THE CALIBRATOR OR SPECIMEN REMAIN UNCHANGED. AS ANY DISSOLVABLE SUBSTANCE CAUSES THIS EFFECT, THE RESULT OF THE MEASUREMENT GIVES NO INFORMATION ABOUT THE IDENTITY AND/OR COMPOSITION OF THE SUBSTANCES DISSOLVED, IF THERE SHOULD BE SEVERAL. THE MEASURED VALUE EXPRESSES IF THE RANGE OF OSMOLALITY OF THE SPECIMEN IS TO BE EXPECTED AS BEING NORMAL FOR A SPECIMEN FROM A HEALTHY HUMAN BEING. OR THE OSMOLALITY SHOWS THAT SOMETHING IS WRONG WITH THE PATIENT. FURTHER MEDICAL EXAMINATIONS WOULD FOLLOW. IN THE CALIBRATOR THE ONLY SUBSTANCE DISSOLVED IS SODIUM CHLORIDE. SO THE VALUE OF THE OSMOLALITY ALSO REPRESENTS THE CONCENTRATION OF SODIUM CHLORIDE. TO MEASURE THE FREEZING-POINT-DEPRESSION. THE SAMPLE IS FROZEN CAREFULLY. THE EXACT TEMPERATURE OF THE FLUID IS MEASURED AT ANY TIME WHILE THE SAMPLE IS COOLED DOWN. THE TEMPERATURE AT WHICH THE FLUID FREEZES TO ICE IS DETERMINED EXACTLY AND THE INTERNAL CALCULATOR OF THE OSMOMETER CALCULATES AND DISPLAYS THE EQUIVALENT OSMOLALITY OF THE LIQUID. IN MATRICES LIKE URINE THE MEASUREMENT SHOWS IF THE KIDNEYS WORK PROPERLY ASSUMABLY.

VITROS Progesterone Reagent Pack For in vitro diagnostic use only. The Vitros Progesterone Reagent Pack quantitatively measures progesterone concentration in human serum and plasma. VITROS Progesterone Calibrators For in vitro use in the calibration of the VITROS Immunodiagnostic System for the quantitative measurement of progesterone in human serum and plasma (EDTA or heparin).

The VITROS Immunodiagnostic System uses luminescence as the signal in the quantitative and semi-quantitative determination of selected analytes in human body fluids, commonly serum and plasma. Coated microwells are used as the solid phase separation system. The system is comprised of three main elements: 1. The VITROS Immunodiagnostic Products range of immunoassay products (in this case VITROS Immunodiagnostic Products Progesterone Reagent Pack, VITROS Immunodiagnostic Products Progesterone Calibrators, which are combined by the VITROS Immunodiagnostic System to perform the VITROS Progesterone assay). 2. The VITROS Immunodiagnostic System instrumentation, which provides automated use of the immunoassay kits. The VITROS Immunodiagnostic System was cleared for market by a separate 510(k) premarket notification (K962919/S1). 3. Common reagents used by the VITROS System in each assay. The VITROS Immunodiagnostic Products Signal Reagent and VITROS Immunodiagnostic Products Universal Wash Reagent were cleared as part of the VITROS Immunodiagnostic Products Total T3 Reagent Pack and VITROS Immunodiagnostic Products Total T3 Calibrators 510(k) premarket notification (K964310). The VITROS System and common reagents are dedicated specifically for use only with the VITROS Immunodiagnostic Products range of immunoassay products.

A urinary protein or albumin (nonquantitative) test system is a device intended to identify proteins or albumin in urine. Idetnification of urinary protein or albumin (nonquantitative) is used in the diagnosis and treatment of disease conditions such as renal or heart diseases or thyroid disorders, which are characterized by proteinuria or albuminuria.

When a sample is mixed with Buffer and Antibody, albumin in the sample combines specificaaly with anti-human albumin antibody (goat) in the Antibody to yeild an insoluble aggregate that causes increases turbidity in the solution. The degree of the turbidity of solution can be measured optically and is proportional to the concentration of albumin in the patient's sample.
