Which set of tests includes BUN, Creatinine, and URR?

• A. Glucose, Sodium, Potassium
• B. Hematocrit, Platelets, WBC
• C. BUN, Creatinine, URR
• D. Albumin, Bilirubin, ALT

Answer: (C)

These tests are used to assess kidney function and dialysis adequacy. BUN (blood urea nitrogen) shows how well the kidneys are clearing urea from the blood, while creatinine is another waste product cleared by the kidneys and helps gauge overall filtration. URR, the urea reduction ratio, measures how effective a dialysis session is at removing urea and is calculated from pre- and post-dialysis BUN values (often expressed as a percentage). Together, BUN, creatinine, and URR focus on waste clearance and the effectiveness of dialysis, making this the correct grouping. The other sets contain parameters for glucose and electrolytes, blood cell counts, or liver enzymes, which do not specifically assess kidney function or dialysis adequacy.
