Question

How can the WBC count be estimated when performing the microhematocrit test?

a) Centrifuge the blood sample
b) Measure the plasma volume
c) Observe the color change in the buffy coat
d) Count the number of red blood cells

Answer 1

The WBC count can be estimated by observing the color change in the buffy coat during the microhematocrit test.

Step-by-step explanation:

The WBC count can be estimated when performing the microhematocrit test by observing the color change in the buffy coat. The buffy coat is a thin layer above the red blood cells in the centrifuged blood sample. It is composed of the white blood cells (WBCs) and platelets. By carefully observing the color change in the buffy coat, which is typically a pale or off-white color, the number of WBCs can be estimated.
