Several tests are used to evaluate kidney function: - Blood Urea Nitrogen (BUN): Measures the amount of nitrogen in the blood that comes from the waste product urea. - Serum Creatinine: Higher levels indicate impaired kidney function. - Glomerular Filtration Rate (GFR): Estimates how well the kidneys filter waste. - Urinalysis: Detects abnormalities such as proteinuria, which can indicate kidney damage.
