LIMITS AND RANGES

Measuring range

MEASURING RANGE

Serum/Plasma: 0.83-30 µg/mL (3.0-108.3 µmol/L)

MANUALLY DILUTE SAMPLES ABOVE THE MEASURING RANGE 1 + 1 WITH PRECISET TDM II DILUENT (0 ΜG/ML) AND REASSAY. MULTIPLY THE RESULT BY 2 TO OBTAIN THE SPECIMEN VALUE.

LOWER LIMITS OF MEASUREMENT

Lower detection limit of the test

SPECIFIC PERFORMANCE DATA

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

PRECISION

Precision was determined using human samples and controls in a modified NCCLS EP5-T2 protocol (repeatability n = 63, intermediate precision n = 63). The following results were obtained on a Roche/Hitachi cobas c 501 analyzer.
