There are more items to check kidney function, so the cost is not quite the same, the most commonly used are urine routine, blood creatinine and urea, and kidney ultrasound, which can be a little better to check the ECT of both kidneys and can clarify the glomerular filtration rate situation. The general cost of urine routine is about 20 yuan, and blood creatinine and urea add up to 20 yuan. Urological ultrasound is$100, and ECT of both kidneys costs between$400 and$500. If all these tests are done, the total cost is about between 700-800 dollars. For the examination of kidney function, the earliest is still the change of urine routine and the positive protein occult blood, when there can still be no complications such as edema and hypertension. Treatment is also the most effective in this period, applying drugs to protect the kidneys as well as reduce urine protein, which can stabilize the kidney function for a long time. By the time creatinine and urea start to rise, it is time to check the kidney ECT to clarify the glomerular filtration rate and exactly how much is left to further improve the assessment of the kidney condition.
