Question

After microscopic examination of a pellet from a centrifuged urine sample, you record RBC and leukocyte counts as elements per?

1) revolutions per minute (rpm) (relative centrifugal force of 400 to 500 g)
2) high-powered field (HPF) (400 magnification)
3) low-powered field (LPF) (100 magnification)
4) milliliter (ml) (with SG <1.008)

Answer 1

The RBC and leukocyte counts in a centrifuged urine sample can be recorded in different units such as revolutions per minute (rpm), high-powered field (HPF), low-powered field (LPF), and milliliter (ml) with a specific gravity (SG) less than 1.008.

Step-by-step explanation:

The RBC and leukocyte counts in a centrifuged urine sample can be recorded in different units:

1. Revolutions per minute (rpm) or relative centrifugal force (g): This measures the number of elements per rotation of the centrifuge.
2. High-powered field (HPF) at 400 magnification: This measures the number of elements per view under a microscope at high power.
3. Low-powered field (LPF) at 100 magnification: This measures the number of elements per view under a microscope at low power.
4. Milliliter (ml) with a specific gravity (SG) less than 1.008: This measures the number of elements per volume of urine.
