How to Use This Calculator
  1. Enter complete blood count values: WBC (K/uL), RBC (M/uL), hemoglobin (g/dL), hematocrit (%), and platelets (K/uL).
  2. Input the differential percentages: neutrophils, lymphocytes, monocytes, eosinophils, basophils.
  3. Enter MCV, MCH, and MCHC for red cell indices.
  4. Review the calculated absolute cell counts and flag any values outside the reference range.
  5. Correlate flagged values with clinical presentation and prior results.
