Are in vitro diagnostic reagent calibrators, calibrators, calibrators, and calibrators the same thing?
The four terms of in vitro diagnostic reagent calibrator, calibrator, calibrator, and calibration solution are essentially the same thing. The English term refers to one, namely "calibrator", and its purpose is to calibrate in vitro diagnostic reagents or systems. Most medical tests are biological measurements, which are basically relative measurements. We must have one or several calibrators of known concentrations, and use IVD reagents to test them on the instrument to obtain the signals of these calibrators (such as absorbance, luminous intensity, etc.), establish the relationship between the concentration value and the signal value, this is the calibration curve (also known as the calibration curve), so that when testing an unknown clinical specimen, with the signal value of the specimen, the calibration curve can be used to estimate the specimen's concentration value. It is conceivable that the known concentration value of the calibrator is very important, it directly determines whether the measured value of the clinical specimen is correct or not, which involves the metrological traceability of the calibrator assignment.
Of these four nouns, the standard name is "calibrator". The calibrator and the calibrator are both popular names. The calibrator emphasizes the liquid state, and the lyophilized calibrator is commonly used. According to the level and use, calibrators are divided into product calibrators and working calibrators. Product calibrators are provided to the user for calibrating reagents. The working calibrator, also known as the master calibrator, or the manufacturer's internal calibrator, the working calibrator is used internally by the manufacturer and plays a very important role in calibrating the manufacturer's standing measurement procedure (standing measurement procedure, The manufacturer's permanent measurement procedure can be simply understood as a conventional inspection system, but with stricter maintenance and quality control, and less uncertainty), passing the accuracy of a higher level of reference material to the product calibrator
