Phlebotomy – Order of Draw Practice Test

Question: 1 / 400

What test is utilized to assess kidney function through blood analysis?

BUN

The test used to assess kidney function through blood analysis is BUN, which stands for Blood Urea Nitrogen. This measurement evaluates the amount of nitrogen in your blood that comes from the urea, a waste product formed from the breakdown of proteins. The kidneys filter urea from the bloodstream, so elevated BUN levels can indicate that the kidneys are not functioning properly or that there are issues with hydration or protein intake.

In contrast, LDL (Low-Density Lipoprotein) is a measure of cholesterol levels in the blood and is associated with cardiovascular health, rather than kidney function. TSH (Thyroid-Stimulating Hormone) is used to assess thyroid function, specifically how well the thyroid gland is working, and does not provide information related to the kidneys. The OGTT (Oral Glucose Tolerance Test) is utilized to diagnose diabetes and assess how the body processes glucose, straying from any kidney-specific evaluation. Thus, BUN remains the key test for evaluating kidney function among the provided options.
