Quality control (QC) measurements ensure the proper
functioning of the analyzer. A QC material for which the
results are known is measured and the results are then
compared against the defined ranges for these known
results.
Use commercially available urine controls, or other
suitable control material. Run a positive and negative
control at least after the weekly calibration and when a
new vial of test strips is opened.
