Kidney disease examination programs include urine, blood, imaging tests and renal puncture biopsy. The most common urine test is urine routine, which can clarify whether there is protein and occult blood in urine, and understand the specific gravity of urine. Secondly, 24-hour urine protein quantification, urine microalbumin creatinine ratio, and urine red blood cell phase difference can be performed to understand the kidney disease. Blood test mainly includes renal function, albumin, electrolytes, related antibodies, etc., which can solve the severity of kidney disease, as well as assist in determining the type of kidney disease. Imaging examination includes urological ultrasound and CT examination if necessary, which aims to clarify the size and shape of kidney and whether there are stones and tumors in combination. Some patients who cannot identify the specific type of disease through the above examinations may need to undergo renal puncture biopsy to identify the specific cause of the disease. Patients with kidney disease are recommended to go to the hospital in time, follow the doctor’s instructions to complete the relevant examinations, identify the cause of the disease, and carry out standardized treatment under the doctor’s guidance.
