Calibration | 合法醫療器材資訊網

Calibration is the foundation of all clinical laboratory testing that insures the accurate reporting of patient results. Calibration is the process that links the analytical signal with the concentration of analyte present in serum, urine or other body fluid.

Calibration uses a series of at least five calibrators containing known concentrations of an analyte. Before beginning calibration a medical laboratory scientist programs the instrument with the concentration of each analyte according to the information provided on the package insert supplied with the calibrator kit. The instrument then measures the calibrator and adjusts the signal to match the given values. Depending on the method, this signal might be potentiometric, photometric, fluorometric, chemiluminescent, nephelometric or turbidimetric. Plotting signal on the Y-axis versus analyte concentration on the X-axis creates a...
