Calibration Laboratory Operations Review 55
TERM EXPLANATION
Calibration Process of testing & adjusting analyzer’s readout to establish correlation between measured & actual
concentrations.
Calibrator Reference material with known concentration of analyte. Programmed into analyzer’s computer for use in
calculating concentration of unknowns. Formerly called standard.
Calibration verification Testing materials of known concentrations (calibrators, controls, proficiency testing samples, patient speci-
mens with known values) to ensure accuracy of results throughout reportable range. Test 3 levels—high,
midpoint, & low. Required every 6 months, when lot # of reagents changes, following preventive mainte-
nance or repair, & when controls are out of range.
