A creatinine clearance is done on a patient with the following results: serum creatinine, 0.6 mg/dL; urine creatinine, 102 mg/dL; urine volume, 1650 mL/24 hours; body surface area, 1.93 m2. Based on the information from calculations above, which of the following is the best interpretation of this patient's creatinine clearance results? 1) Within the normal range 2) Above normal, probably because the 24-hr urine collection was not completed correctly 3) Above normal 4) Below normal no references, just homework
The laboratory received a 24-hour urine collection from a 26-year old male (body surface area = 2.34m2), and the total urine collection volume measured 800 mL in 24 hours. After creatinine determinations were performed by the alkaline picrate method, interpret the result. Plasma creatinine: 1.2 mg/dL Urine creatinine: 150 mg/dL a. The creatinine clearance of the patient is above reference range. b. The creatinine clearance of the patient is below reference range. c. The creatinine clearance of the patient is within reference range. d. The creatinine clearance of the patient is borderline high.
