Verifying the precision of a measurement procedure against a performance claim and estimating the bias (CLSI EP15-A3)

Learn how to verify that a measurement procedure meets performance requirements before introducing a new measurement procedure into the laboratory, after maintenance to the measuring system, or upon failing a proficiency test or inspection.

In this tutorial you will use the CLSI EP15-A3 procedure to verify the precision against the manufacturer’s claim and estimate the bias using proficiency testing materials.

  1. Estimating precision
    Estimate the precision of the measurement procedure.
  2. Testing precision against a performance claim
    Test if the precision meets the manufacturer's performance claim.
  3. Identifying and excluding outliers
    Dealing with outliers and assessing their impact.
  4. Estimating bias
    Estimate the bias using reference materials.
