D
Feedback:
The creatinine clearance test uses a collected urine specimen to indicate glomerular filtration rate and renal insufficiency. A urinalysis (UA) provides much information about the condition of the bladder and kidneys as well as other body systems. The blood urea nitrogen (BUN) test determines how efficiently the glomeruli remove the nitrogenous wastes (urea) that result from protein metabolism. Uric acid studies may be obtained from urine or serum. The main diagnostic purpose of obtaining a uric acid level is to evaluate the client for gouty arthritis or kidney disease.
