Testing Kidneys: The accurate way to assess one's renal function is a with a 24 hour urine collection for a creatinine clearance (cc). Depending of the result of the cc, one can then be classified in a stage of chronic kidney disease (ckd). Symptoms of patients with stage 1 or 2 (ckd) may be minor. Patients in stage 4 will have anemia and may feel fatigued quite easily. See a nephrologist for more information.

Subtle: Your kidney function is tested routinely whenever you get blood work done. The blood urea nitrogen and creatinine are the assays. The third test of kidney function is the ability to concentrate urine which isn't routinely done; the urinalysis looks for specific kidney problems and more. Early chronic kidney disease usually only produces vague feelings of ill health.
