Final answer:
Leaving a urine sample at room temperature for 3 hours can affect specific gravity measurements and bacterial content.
Explanation:
Specific gravity is a measure of the quantity of solutes per unit volume of a solution in urine. Leaving a urine sample at room temperature for 3 hours would affect the specific gravity as it can lead to changes in the concentration of solutes which affects the specific gravity reading. This can impact the accuracy of diagnostic tests relying on specific gravity levels.
An increase in temperature can also lead to bacterial growth in the urine sample, affecting the bacterial content. However, factors such as color and protein content might not be significantly altered by room temperature within 3 hours.
