Q. A 32-year-old woman presents to your primary care clinic with complaints of fatigue and pallor for the past few weeks. She has no significant medical history and is not taking any medications. On physical examination, scleral icterus is noted. A complete blood count (CBC) is ordered, and the results show a low hemoglobin level and a high Mean Corpuscular Hemoglobin Concentration (MCHC). How do you define Mean Corpuscular Hemoglobin Concentration (MCHC)?
