When is the kidney function test done, and what tests are needed to check the kidney function?

What do I need to do before a kidney function test?

Kidney function tests are often used to measure changes in kidney function using urine microscopy and chemistry tests, as well as certain chemical tests of the blood. Therefore, special attention should be paid to how to collect urine samples correctly. There are many points to pay attention to, and the collection of urine samples can directly affect the results of the examination and make the diagnosis wrong.

The precautions for urine routine in renal function tests are that the urine specimen for the examination is generally the most appropriate for morning urine testing, which is the first time to urinate when you get up in the morning. Because the urine at this time is concentrated overnight in contrast.

Thicker. The effect of eating and drinking during the day is more observant than diluted urine. At the same time, it can also avoid the influence of exercise, emotion, etc. Morning urine should be sent for testing within 1 hour after receiving the urine to avoid urine preparation, and fresh urine specimens are more consistent.

compliance with the requirements of the inspection.

In addition to morning urine, urine specimens are also required to be midstream urine to avoid inflammation of the urethral meatus, leucorrhea and other substances contaminating the urine and affecting the test results. Female patients should pay special attention to the fact that urinalysis is generally not suitable during menstruation and in the days before and after menstruation. The main purpose is to avoid menstrual blood mixing into the urine, causing the illusion of hematuria and affecting the test results.

In addition, patients must avoid heavy alcohol consumption, overwork, and eating large amounts of fish and meat before the kidney function check, which can affect the results of the test. Before the renal function test, patients should eat a light diet, pay attention to rest, and avoid strenuous exercise and overwork.

If you've got all these prep activities done, feel free to go.

Renal function test is generally an examination to check whether there is a disease in the kidneys, you can see whether there is an abnormality in creatinine and other items, you can go to the urology department of a regular hospital to do an examination to see if there is any abnormality, if the examination is normal, don't worry, these symptoms are generally related to allergies, allergies can take anti-allergic drugs such as Claritin, chlorpheniramine**, **itching, calamine lotion can be used**, in addition, desensitization can be taken according to allergens****, do not contact allergens, do not eat spicy food, pay attention** Hygiene.

The kidney function check is fasting, fasting to remove venous blood, but if you are worried that the eye swelling is caused by the kidneys, not only should you check the kidney function, but also recommend a urine check to see if there is urine protein.

Indicators of preliminary response to renal function: urine protein.

The more plus signs (+) in the test results, the more abnormal they are.

Urine protein in urinalysis is a relatively early indicator of abnormal kidney function, and when (+) appears, it is best to go to the hospital for blood tests and 24-hour urine protein quantification for further diagnosis.

Protein detection in urine may also be a physiological phenomenon after excessive exercise, fitness and eating protein powder, etc., so it is necessary to see a doctor for re-examination in time.

Common indicators of renal function: serum creatinine, blood urea, and blood uric acid.

Methods to check renal function include: first, urine routine to see whether there are red blood cells and urine protein in the urine; second urinary ultrasound to see if there is a mass or fluid accumulation in the kidneys; the third biochemical series, to see if the value of creatinine in the blood is increased; Fourth, if necessary, a puncture pathological examination of the kidneys can be done.

Laboratory tests are required, and general renal function items include: serum creatinine, urea, uric acid. With urine creatinine, the glomerular filtration rate can be counted, and the renal ECT examination is more intuitive, but not every hospital can do it, cystatin C, which can detect changes in kidney function earlier, and urine routine is a necessary item.

1. Urine routine examination: abnormal urine is one of the main manifestations of kidney patients, so urine test is a preferred means to diagnose kidney disease and understand kidney disease. 2. Imaging examination

Renal function.

Renal function tests are an experimental method to study kidney function. Urine microscopy and chemistry tests, as well as certain chemical tests of the blood, are commonly used to measure changes in kidney function. Commonly used measurement items are:

Urine sample, urine specific gravity, urine sediment microscopic examination, urea nitrogen, creatinine, non-protein nitrogen quantification, phenol red excretion test, etc.

The renal function tests performed during the physical examination include blood tests, B-ultrasound, etc., and the comprehensive renal function tests include 24-hour urine protein quantification, etc., and renal function tests.

Many people's kidney function is not good, it is extremely affecting the pregnancy of the baby, this can be checked, the test is not good, how to do the kidney function test, and share it with you.

Method steps.

First of all, the first urine test is taken when you wake up in the morning. This is necessary and must be remembered.

And then. Renal function test (venous blood drawing) test content: including blood creatinine, glomerular filtration function, endogenous creatinine clearance, blood urea nitrogen). Keep this order in mind for checking.

Finally, urine routine (urine test) examination contents: including urine volume, urine color), urine specific gravity fibrillation), urine glucose, urine protein and other items. This is the last time, and we still have to stick to it. Ode to the elderly.

Be mentally prepared, don't eat anything before the examination, don't drink water, have an examination on an empty stomach, be prepared to face the disease, go to a blood test, and do color ultrasound.
