Question 4

What does specific gravity measure in a urine sample?

Accepted Answer

The concentration of solutes compared to pure water

Answer

Specific gravity measures the density and concentration of dissolved substances (solutes) in urine relative to pure water, reflecting the kidneys' ability to concentrate or dilute urine.

Question 5

Which of the following is an abnormal finding when examining urine under a microscope?
