Question

which type of blood may be used for a hematocrit?
a. arterial or venous
b. capillary or venous
c. arterial or capillary
d. arterial, capillary, or venous

Explanation:

Hematocrit measures the proportion of red blood cells in blood. Capillary (from finger - stick) or venous (from vein puncture) blood can be used. Arterial blood is not typically used for routine hematocrit as it is more invasive and has no advantage over capillary or venous for this test.

Answer:

B. capillary or venous
