 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Define mean cell haemoglobin concentration (MCHC).
 A The average volume per red cell B The coefficient of variation of red cell volume C The average conentration of ahemoglobin in given volume of packed D The average mass of haemoglobin per red cell
Explanation:

Detailed explanation-1: -MCHC indicates the amount of hemoglobin per unit volume. In contrast to MCH, MCHC correlates the hemoglobin content with the volume of the cell. It is expressed as g/dl of red blood cells or as a percentage value. The normal values for MCHC are 34 ± 2 g/dl.

Detailed explanation-2: -MCHC refers to the average concentration of hemoglobin in a given volume of red blood cells. A normal MCHC level for an adult is 31-37 grams per deciliter (g/dL). MCHC values by themselves are not always a sign that a person has any underlying health problems but may prompt a doctor to do further tests.

Detailed explanation-3: -The reference ranges for hemoglobin (Hb) concentrations in adults are as follows : Male: 14-18 g/dL or 8.7-11.2 mmol/L (SI units) Female: 12-16 g/dL or 7.4-9.9 mmol/L (SI units)
