A Clinical Laboratory Professional Performed a Procedure to Verify the Hemoglobin

A clinical laboratory professional performed a procedure to verify the hemoglobin reportable range on the Cell-Dyn 4000.The highest level of linearity check material was 22.0 g/dL.This material was run several times with 21.7 g/dL, representing the mean.How should this finding be interpreted?

A) The result is within the tolerance limits, and the reportable range is verified.
B) The result exceeds the tolerance limits, and the procedure should be repeated with new check material.
C) The result exceeds the tolerance limits, and additional check material should be run in the upper limits of the reportable range.
D) The result exceeds the tolerance limits, and the verification of reportable range should be repeated after the instrument is recalibrated.
