Reference Ranges Used

MCH (Mean Corpuscular Hemoglobin) - Adult 27–33 pg
MCHC - Adult 32–36 g/dL
MCV (Mean Corpuscular Volume) - Adult 80–100 fL

Formula & Clinical Notes

Formula

MCV = (Hct × 10) / RBC · MCH = (Hb × 10) / RBC · MCHC = (Hb × 100) / Hct

Clinical Notes

Normal ranges: MCV 80-100 fL, MCH 27-33 pg, MCHC 32-36 g/dL. Low MCV with normal MCHC suggests microcytic anemia (e.g., iron deficiency, thalassemia); high MCV suggests macrocytic anemia (e.g., B12/folate deficiency).
