Final answer:
The correct formula for Mean Cell Hemoglobin (MCH) is MCH = Total Hemoglobin (Hb) ÷ Red Blood Cell count (RBC), a measurement of the average hemoglobin content per red blood cell.
Step-by-step explanation:
The formula for Mean Cell Hemoglobin (MCH) is none of the options provided. The correct formula for MCH is actually: MCH = Total Hemoglobin (Hb) ÷ Red Blood Cell count (RBC), usually expressed as picograms (pg) per cell. MCH is a calculation of the average amount of hemoglobin inside a single red blood cell (erythrocyte). Hemoglobin is the oxygen-carrying compound in erythrocytes, and its levels are important for diagnosing conditions like anemia.
The mean cell hemoglobin (MCH) is a measurement of the average amount of hemoglobin in each red blood cell. It is calculated by dividing the total hemoglobin (Hb) by the total red blood cell count (RBC count).
For example, if the total hemoglobin is 15 grams and the total red blood cell count is 5 million cells, the MCH would be 3 picograms (pg/cell).
