The mean cell hemoglobin concentration (MCHC) tells you how much hemoglobin there is on average in a red cell. If the MCHC is low, the cells are called hypochromic. If the MCHC is normal, the red cells are called normochromic. WebAnemia is an absolute decrease in RBC numbers, hemoglobin concentration, or PCV. Signs include pale mucous membranes, increased heart rate, and hypotension. Diagnosis can be made by CBC, but may be refined by additional tests.
