What is the mean cell hemoglobin concentration (MCHC) if Hgb is 15 g/dL and Hct is 47 mL/dL?

What is the mean cell hemoglobin concentration (MCHC) if Hgb is 15 g/dL and Hct is 47 mL/dL?

• A. 9.5% (.095)
• B. 10.4% (.104)
• C. 31.9% (.319)
• D. 33.3% (.333)

Answer: (C)

To calculate the mean cell hemoglobin concentration (MCHC), the formula used is: \[ \text{MCHC} = \frac{\text{Hemoglobin (Hgb)}}{\text{Hematocrit (Hct)}} \times 100 \] Given that the hemoglobin (Hgb) is 15 g/dL and the hematocrit (Hct) is 47 mL/dL, we can apply these values to the formula. First, convert the Hct from mL/dL to a percentage by recognizing that 1 mL/dL is equivalent to 1%. Thus, 47 mL/dL is equal to 47%. Now we can substitute the values into the MCHC formula: \[ \text{MCHC} = \frac{15 \, \text{g/dL}}{47 \, \text{mL/dL}} \times 100 = \frac{15}{47} \times 100 \] Calculating \( \frac{15}{47} \) gives approximately 0.319. When you multiply this by 100 to express it as a percentage, you get about 31.9%. Thus, the mean

To calculate the mean cell hemoglobin concentration (MCHC), the formula used is:

[ \text{MCHC} = \frac{\text{Hemoglobin (Hgb)}}{\text{Hematocrit (Hct)}} \times 100 ]

Given that the hemoglobin (Hgb) is 15 g/dL and the hematocrit (Hct) is 47 mL/dL, we can apply these values to the formula.

First, convert the Hct from mL/dL to a percentage by recognizing that 1 mL/dL is equivalent to 1%. Thus, 47 mL/dL is equal to 47%.

Now we can substitute the values into the MCHC formula:

[ \text{MCHC} = \frac{15 , \text{g/dL}}{47 , \text{mL/dL}} \times 100 = \frac{15}{47} \times 100 ]

Calculating ( \frac{15}{47} ) gives approximately 0.319. When you multiply this by 100 to express it as a percentage, you get about 31.9%.

Thus, the mean
