Question

On testing a blood sample it is found that it contains 15 g of Hb per decilitre of blood sample and a PVC of 0.45. Find the mean cell haemoglobin concentration for the blood sample:

• A. 33.3 g/dl
• B. 28.3 g/dl
• C. 33.9 g/dl
• D. 31.2 g/dl

Hint:

To find MCHC, just divide the hemoglobin content (in g/dl) by the PCV (in decimal). The result is the hemoglobin concentration in red blood cells.

Answer 1

The Correct Option is A

The mean cell hemoglobin concentration (MCHC) is calculated using the formula:
\[ \text{MCHC} = \frac{\text{Hemoglobin (Hb)}}{\text{Packed Cell Volume (PCV)}} = \frac{15}{0.45} \]
Now, calculating this:
\[ \frac{15}{0.45} = 33.3 \text{ g/dl} \]
Therefore, the MCHC is 33.3 g/dl.
