What preparations need to be made before renal function puncture needle examination?

Renal function tests often use urine microscopy and chemical examinations, as well as certain blood chemical examinations and other indicators to measure changes in renal function. Therefore, we must pay special attention to how to collect urine specimens correctly. There are many things to pay attention to. The collection of urine samples can directly affect the results of the examination and make the diagnosis mistaken.

Precautions for the urine routine in the renal function test are: the urine specimens to be checked are generally the most appropriate to take the morning urine test, and the morning urine is the first urination when you get up in the morning. Because the urine at this time has been concentrated overnight compared to

Thicker. It is more meaningful to observe than urine that is diluted by the influence of diet during the day. At the same time, the influence of sports and emotions can be avoided. After receiving the morning urine, it should be submitted for examination within 1 hour to avoid urine preparation. Fresh urine specimens are more consistent.

Meet the inspection requirements.

In addition to morning urine, urine specimens also require mid-section urine to avoid urethral orifice inflammation and leucorrhea that pollute the urine and affect the test results. Female patients should pay special attention to routine urine routines during menstruation and a few days before and after menstruation. The main purpose is to prevent menstrual blood from mixing into the urine, causing the false appearance of hematuria and affecting the test results.

In addition, patients must avoid a lot of alcohol, overwork, and eating big fish before checking kidney function, all of which will affect the test results. The patient should have a light diet before the renal function test, pay attention to rest, and avoid strenuous exercise and overwork.
