CALIBRATION

Calibration interval may be extended based on acceptable verification of calibration by the laboratory.

 Serum/plasma application (IGG-2):
Calibrators S1: H2OS2-S6: C.f.a.s. Proteins
Multiply the lot-specific C.f.a.s. Proteins calibrator value by the factors below to determine the standard concentrations for the 6‑point calibration curve:
S2: 0.100 S5: 1.00
S3: 0.250 S6: 3.14
S4: 0.501
Calibration mode RCM
Calibration frequency Full calibration▪after reagent lot change▪as required following quality control procedures
 CSF application (IGGC2):
Calibrators S1: H2OS2-S6: C.f.a.s. PUC
Multiply the lot-specific C.f.a.s. PUC calibrator value by the factors below to determine the standard concentrations for the 6-point calibration curve:
S2: 0.0431 S5: 0.331

SPECIFIC PERFORMANCE DATA

Representative performance data on the analyzers are given below. Results obtained in individual laboratories may differ.

PRECISION

Serum/plasma and CSF:

PRECISION WAS DETERMINED USING HUMAN SAMPLES AND CONTROLS IN AN INTERNAL PROTOCOL WITH REPEATABILITY (N = 21) AND INTERMEDIATE PRECISION (3 ALIQUOTS PER RUN, 1 RUN PER DAY, 21 DAYS). THE FOLLOWING RESULTS WERE OBTAINED:

RESULTS FOR INTERMEDIATE PRECISION WERE OBTAINED ON THE MASTER SYSTEM501 ANALYZER.
