The examination of kidney function is divided into basic examination items, such as creatinine, urea nitrogen and uric acid, which are the three kidney functions tested by drawing blood, and the general test price is about 20-30 yuan; as some urine is abnormal in kidney disease, routine urine examination is needed, i.e. about 20 yuan; there will also be simultaneous examination of liver function albumin to see if there is hypoproteinemia, which is generally about 20 yuan; generally like routine examination, blood sampling is about 100 yuan; if the kidney is measured by ultrasound, it is about 100 yuan, and the specific cost varies from hospital to hospital. If there is a problem with the basic test items, then the glomerular filtration rate needs to be checked further, and the price of the test may be relatively high because kidney function is usually tested for abnormalities, and the glomerular filtration rate is only checked when the kidney is contracted, and the price is about 500-1000 RMB, and there may be some differences according to different hospitals’ charges.
