BUN/Creatinine: Serum should be tested for blood urea nitrogen and creatinine to assess for the presence of kidney dysfunction. A complex formula is used to estimate kidney function or estimated glomerular filtration rate. This formula utilizes serum creatinine, age, sex, and race. Sometimes we utilize another serum study called cystatin c which may give us more information. Urinalysis is also needed.

Blood and urine: Urinalysis with tests for protein, glucose, blood, bilirubin, pH and specific gravity, blood tests for na, k, cl, creatinine, urea, bicarbonate (sodium bicarbonate) are a good starting point. Many other tests may be needed depending on these chemistry tests as well as hematology and urine microscopy, ultrasound and serologic testing.
