NettetJust for added clarification, the AMR (analytical measurement range) is the range of results confirmed to be linear (read: accurate and precise) without dilutions. The reportable range is the low end of the AMR to the high end of the max dilution allowed. Sometimes the AMR and reportable range are the same and sometimes they’re not. NettetThe Linearity module can (optionally) evaluate accuracy, reportable range, and precision, as well as linearity. It can also produce a report specifically designed to meet regulatory requirements for calibration verification, and calculate the probability of proficiency testing failure.
