Advice 1: What tests to take to check the kidneys

The kidneys play a vital role in the functioning of the body. Therefore, if you suspect kidney disease (pain in the lumbar region, frequent or, on the contrary, rare urination, change of urine color, etc.) should contact to the doctor. To check kidneys should undergo examinations (e.g. ultrasound, MRI, and also to pass a series of tests.

Urinalysis and biochemical analysis of blood

To assess whether kidney function of their physiological capabilities, depending on the age of the patient, prescribe biochemical analysis of blood and urine analysis.

Urine for General analysis of collected in the morning, before it is forbidden to take any medicines. Analysis must take place no later than 1.5 hours, while avoiding cooling of the urine is below 0oC. Otherwise, some components of urine can precipitate that will distort the picture analysis. In General, the analysis of the verification is exposed to the appearance of urine, as well as its physico-chemical, biochemical and microbiological parameters.

Biochemical analysis of blood is performed on an empty stomach. It is not recommended prior to analysis to drink coffee, strong tea, milk, sweet drinks, you can drink water or weak tea. The main parameter by which to judge the condition of the kidney is the concentration of urea in the blood. In a healthy person in 1 liter of blood should be from 2.5 to 8.3 mmol of urea. More than exceeded upper threshold concentrations, the stronger the kidneys. For example, the concentration to 20 mmol/liter tells about the violations of moderate severity, from 20 to 35 mmol/l – severe impairment of renal function, and if the urea concentration exceeds 50 mmol/liter, this indicates a very heavy defeat with a poor prognosis.

What other tests can be assigned

To check the kidneys, often prescribed two more kinds of urine analysis: Nechiporenko and zimnitskiy. If your doctor has prescribed analysis according to Nechyporenko, you must collect the middle portion of urine in amounts up to 10 milliliters. This analysis allows to determine the content of leukocytes and erythrocytes in 1 milliliter of urine.

If assigned analysis in General, urine should be collected in the course of a day at intervals of 2-3 hours. You usually have to collect 8 samples (rarely 12). Examining the number and density of urine in each sample, the doctor can conclude whether kidney function normal levels. For example, the normal density of urine day should be in the range of 1010-1025 grams/liter, night – not exceeding 1035 grams/liter. At a density below the lower limit of the possible uncomplicated pyelonephritis or kidney failure. If the density exceeds the upper limit, it may be dehydration or severe pyelonephritis.

Advice 2 : What tests are needed to check the kidneys

The kidneys are important organs. The main function they perform is the allocation produced by the metabolism of harmful toxins received from the environment toxins, drugs and other substances. Must once a year undergo examination and tests to check kidney health, as diseases of the body are asymptomatic.

General clinical analysis of blood can reveal the presence of inflammation in the body, including the kidneys. The increase in the erythrocyte sedimentation rate, abnormal increase of leukocytes in the blood is detected in various inflammatory processes, acute and chronic infections. The blood General clinical analysis of rent from the finger in the morning on an empty stomach.
Need to donate blood for biochemical research, including quantitative determination of total protein, urea, creatinineand uric acid, potassium and sodium. The total protein in normal adult blood is 62-83 g/L. One of the reasons for reducing the amount of total protein in the blood can be increased its loss with urine in renal disease.

Normal value of urea in the blood of an adult person is considered to be a 3.5-8.3 mmol/L. the increase in the concentration of urea is an important sign of violation of renal excretory function. Together with the urea in the blood determine the content of creatinine. Indicators of creatinine depend on muscle mass, so the rate depends on the sex of the person taking the analysis. For men it is: 44-100 µmol/l for women: 44-88 µmol/l in the presence of renal dysfunction creatinine in the blood increases.

Standards of uric acid levels vary depending on gender. For middle-aged men the norm of uric acid is 0.10-0.40 mmol/l, and for middle-aged women - 0,24-0,50 mmol/L. Elevated levels of uric acid levels may indicate a disruption of the kidneys.

When kidney disease increased amount of potassium and sodium. Blood sampling for biochemical study was conducted in the morning on an empty stomach. Valid on the day of delivery of the analysis is to drink a glass of water. Before the study should follow a diet that excludes the consumption of fatty and fried foods.
General urine analysis is the primary analysis, confirming the presence of renal dysfunction. Urine for General analysis surrenders morning, after showering with soap and water. In a sterile container for biological material, purchased at the pharmacy, going to an average portion of urine newly issued. Capacity is marked with the indication of surname, name, patronymic and date of delivery and delivered to the laboratory in a short time.

Change the color of urine, the relative density of the reaction, the presence of turbidity violation occurs when the filtration ability of the kidneys. Increase amounts of protein, erythrocytes, leukocytes, the appearance of cylinders (granular, waxy, epithelial, erythrocyte) occurs when changes in the urinary system.
The tests needed to check kidney, is carried out in specialized laboratories. The study is performed on the basis of a doctor's referral for free. You can take the tests for a fee without a doctor's referral.
