Renal function is usually checked by blood creatinine, urea nitrogen, urine routine and 24-hour urine protein quantification.
Patients with renal insufficiency usually show elevated blood creatinine, urea nitrogen, cystatin C, blood β2-microglobulin and blood uric acid, and most of them have high blood pressure, as well as abnormal urinalysis (urine protein, urine red blood cells or urine white blood cells, tubular pattern and so on), 24-hour proteinuria more than 150mg and so on.
Kidney function is usually checked by blood creatinine, urea nitrogen, urine routine, 24-hour urine protein quantification. If the test report suggests that the urine red blood cells are significantly higher than normal, glomerular disease can be further ruled out by the abnormal red blood cell rate in urine.
If the test report suggests elevated urinary leukocytes or tubular pattern in urine, acute interstitial nephritis, acute pyelonephritis, chronic pyelonephritis, vasculitis-associated renal damage and other renal tubular diseases can be excluded.
Patients with abnormal renal function should go to the hospital in time for consultation and standardized treatment under the guidance of professional physicians.
