A patient's hematology results indicate an RBC count of 4.68 X 10^12/L, a Hemoglobin of 1.33 g/L and a Hematocrit of 0.451. What is the patient's mean corpuscular hemoglobin (MCH)?

To calculate the mean corpuscular hemoglobin (MCH), the formula used is:

[ \text{MCH} = \frac{\text{Hemoglobin (g/L)}}{\text{RBC count (10^12/L)}} ]

In this scenario, the provided values are:

• Hemoglobin = 1.33 g/L

• RBC count = 4.68 x 10^12/L

By substituting these values into the formula, you first need to ensure the units are consistent. Here, the hemoglobin is provided in grams per liter, and the RBC count is in trillion cells per liter.

Calculating the MCH:

[ \text{MCH} = \frac{1.33 , \text{g/L}}{4.68 , x , 10^{12} , \text{cells/L}} ]

To convert hemoglobin from grams to picograms (pg), remember that 1 g = 1,000,000,000 (10^9) pg. Therefore:

[ \text{MCH} = \frac{1.33 , (1.33 \times 10^9 , \text{pg})}{4
