Understanding CBC Components & What Abnormal Results Mean
White blood cells (WBC) rise in infections, inflammation, stress, and some blood cancers. A normal adult range is typically about 3.6–11.0 ×109/L. Marked leukocytosis (very high WBC) may require urgent evaluation. :contentReference[oaicite:1]{index=1}
Red blood cells (RBC), Hemoglobin (Hgb), Hematocrit (Hct) measure oxygen-carrying capacity. Typical adult Hgb ranges are ~13.5–17.5 g/dL (men) and 12.0–16.0 g/dL (women). Low values suggest anemia and need investigation for bleeding, iron/vitamin deficiencies, or chronic disease. :contentReference[oaicite:2]{index=2}
Red cell indices (MCV, MCH, MCHC, RDW) help subtype anemia: small cells (low MCV) often point to iron deficiency or thalassemia; large cells (high MCV) suggest B12/folate deficiency or alcohol effect. RDW elevation means mixed-size cells (often iron deficiency). :contentReference[oaicite:3]{index=3}
Platelets are crucial for clotting. Typical adult range is about 150–400 ×109/L. Counts <50 ×109/L increase bleeding risk; very low counts (<20–10 ×109/L) may cause spontaneous bleeding and often prompt urgent care or transfusion in the right context. :contentReference[oaicite:4]{index=4}
FAQs
- Q: Are lab ranges exact?
A: No — ranges vary slightly by lab, method, altitude, and age. Use your lab's reference interval when available. - Q: Should I panic if one number is off?
A: Not usually — minor deviations are common. Discuss persistent or large abnormalities with your doctor.
