Lab-specific.

Complete Blood Count and Differential

Absolute neutrophil count (ANC) — lab reference

Clinical action thresholds differ from statistical reference intervals.

Review absolute count and clinical context.

Complete Blood Count and Differential

Mean corpuscular hemoglobin (MCH) — lab reference

Analyzer-specific. Review with MCV and MCHC.

Complete Blood Count and Differential

Mean corpuscular hemoglobin concentration (MCHC) — lab reference

Analyzer-specific; hemolysis and cold agglutinins may interfere.

Complete Blood Count and Differential

Mean corpuscular volume (MCV) — lab reference

Macrocytosis and microcytosis require cause-specific interpretation.

Complete Blood Count and Differential

Mean platelet volume (MPV) — lab reference

Highly analyzer- and handling-specific. Consider trend rather than isolated value.

Complete Blood Count and Differential

Altitude, smoking, hydration, androgen therapy, and pregnancy may shift values.

Complete Blood Count and Differential

Red cell distribution width (RDW-CV) — lab reference

Useful with MCV for mixed nutrient deficiencies and evolving anemia.
