Kidney function is commonly measured through blood tests and urine tests. The most common blood tests are serum creatinine and Blood Urea Nitrogen (BUN). Urine tests may include urinalysis and 24-hour urine collection to measure protein levels. GFR is a key indicator of kidney function, calculated based on serum creatinine, age, gender, and body size. Nurses should be proficient in interpreting these tests to provide accurate patient assessments.
