What if my calibration verification fails?
Repeat calibration verification procedure as follows:

  1. First, confirm that your calibrator set point is specifically intended for the reagent you are using and that your daily controls are within limits.
  2. Using a new bottle of reagent and freshly prepared (unopened) calibrator, repeat entire study.
  3. Check the dynamic range of your instrument and make sure you are not challenging the system outside this range.
  4. Highest point failure:  You can either delete the highest point that failed and use your next highest point as the upper limit of your reportable range, OR pool equal amounts of the two highest points and assay your new point. In this case, your target value for the new point will be the average of the two target values used. Verichem strongly recommends using Class A volumetric glassware for preparing dilutions.
  5. Low point failure: Typically, this is not clinically significant. The Laboratory Director is responsible for the decision to accept or reject the study.
  6. If your failure is in the mid level range, you can delete the rogue point as long as the remaining points are within specified limits.
