Answer

Electrolytes, blood urea nitrogen (BUN), and creatinine levels are used to identify renal impairment. A complete blood cell (CBC) count and smear help exclude microangiopathic anemia. Dipstick urinalysis can be used to detect hematuria or proteinuria (renal impairment), and microscopic urinalysis can be used to detect red blood cells (RBCs) or RBC casts (renal impairment). Optional studies include a toxicology screen, pregnancy test, and endocrine testing.
