DUrine Urobilinogen
Answer:
D. Urine Urobilinogen
Read Explanation:
Urine Urobilinogen - Primarily used as a liver function test and to evaluate hemolytic conditions. Urobilinogen is formed in the intestine by the breakdown of bilirubin. Elevated levels usually point to liver dysfunction (such as hepatitis or cirrhosis) or excessive breakdown of red blood cells (hemolysis).
Blood Urea Nitrogen (BUN)-A standard renal function test that measures the amount of nitrogen in the blood coming from the waste product urea, reflecting kidney filtration efficiency.
Serum Creatinine- A key renal function test measuring creatinine—a breakdown product of creatine phosphate from muscle metabolism—which is excreted almost entirely by the kidneys.
Creatinine Clearance - A direct renal function test (often using a 24-hour urine collection alongside serum creatinine) used to estimate the Glomerular Filtration Rate (GFR) and evaluate how well the kidneys filter waste.
