Steps for interpreting the white blood cell parameters of a complete blood count.
| Step 1. | Ensure that NRBCs or other conditions are not falsely affecting the WBC; correct the WBC if needed, before proceeding. |
| Step 2. | Examine the WBC for variations in the total number of wbcs. |
| Step 3. | Interpret absolute differential counts against appropriate reference intervals using proper terminology. |
| Step 4. | If absolute counts are not available from an instrument, use relative counts (i.e. percentages) to calculate absolute values. |
| Step 5. | Make note of immature cells in any leukocyte cell line reported in the differential that should not appear in normal peripheral blood. |
| Step 6. | Make note of any morphological abnormalities of wbcs. |
| Step 7. | Correlate the wbc findings with rbc and platelet findings for a complete clinical assessment of the patient's blood picture. |
