Q: Is external Quality Control available/required?
A: No, the Performance Monitor is an "analyte" or "reactivity" control (derived from hemoglobin) and provides adequate QC. However, if laboratory procedures manual or local regulations require external control testing, follow those guidelines. QC for the pH area can be done using 2 levels (neutral—pH 7 and acid—pH 2-4) of commercially available pH buffers. |
