If you draw a patient's blood for Bun/Creatine, which body organ are you checking?

Heart
Liver
Kidney
Brain

The correct answer is: Kidney

Bun/Creatinine is a blood test used to evaluate kidney function. This test measures the levels of blood urea nitrogen (BUN) and creatinine. High levels of BUN and creatinine may indicate that the kidneys are not functioning properly. Choice A, the heart, is not directly involved in this test and choice D, the brain, is not affected by kidney function. Choice B, the liver, may indirectly affect this test as it is responsible for removing waste products from the blood, but it is not the specific organ being checked for in this case. Therefore, choice C, the kidneys, is the correct answer.
