Altitude, smoking, hydration, androgen therapy, and pregnancy may shift values.
Your lab may use its own range. Symptoms, medicines, and the types of white blood cells also matter.
Ask your clinician to consider altitude and iron/B12/folate status. Pregnancy requires trimester-specific ranges.
Hydration and altitude are major modifiers. Ask your clinician to review alongside hemoglobin and RBC indices.
Macrocytosis and microcytosis require cause-specific interpretation.
The test method matters. Ask your clinician to review with MCV and MCHC.
Analyzer-specific; hemolysis and cold agglutinins may interfere.
Local analyzer range governs. Ask your clinician to review trends and collection artifacts.
Highly analyzer- and handling-specific. Ask your clinician to consider trend rather than isolated value.
Clinical action thresholds differ from statistical reference intervals.
Relative percentage can mislead; review absolute count.
