7- Now take all 3 levels of controls, LOW, NORMAL, HIGH, and run them 1 time each as a regular
patient analysis. When the cycles are complete, note only the RDW results and compare them to the
control Assay values for RDW, on the Assay sheet. Verify that the RDW results are somewhat close to
the Mean Assay values and within the ranges as specified for all 3 Levels.
8- The RDW calibration is now complete. Be sure to monitor your RDW results and verify that they
fall within your patient population.
9- Verify that Normal RDW results will be within the established ranges set in the setup menu. See
Section 5,
Certain Pathological conditions will affect the RDW results. See (See Section 1,

After manually editing the calibration coefficients, it is highly recommended to run
Quality Control. Verify that all levels of control material are within their specified pa-
rameter ranges. Verify that there are no error flags (H, L, *, $, ! for HGB) associated
with all levels of Quality control results.
