OPTi CCA-TS2 User Manual

Operator’s Manual – OPTI CCA-TS2 BUN-3
ANALYTES BUN/UREA
Whole Blood
Within-run precision in whole blood samples was evaluated at 3 different concentrations on the OPTI
CCA-TS2. The table below shows the Averages, Standard Deviations and % CV calculated from 10
samples for each level.
BUN (mg/dL) Whole Blood
Level 1 Level 2 Level 3
Average 6.03 26.61 85.59
St. Dev 0.03 0.25 0.97
%CV 0.53% 0.93% 1.13%
n 10 10 10
Linearity
Wherever possible, linearity for the OPTI CCA measurement has been established against reference
materials or methods. BUN(urea) linearity in serum is by measurement of N.I.S.T. Standard Reference
Material 909b in Frozen Human Serum (BUN
NIST
). No changes were made to the BUN(urea) sensor or
the measurement principle, so the traceability of the OPTI CCA-TS2 is equivalent to the OPTI CCA.
