Kidney disease testsKidney problems do not develop during the night. Your kidney function, naturally, begins to decrease after crossing 30 years. And if you develop a kidney problem later in life depends largely on your lifestyle and diet. In most cases, kidney problems are caused as a result of a primary condition such as diabetes, hypertension or high cholesterol Levels Because the symptoms of kidney disease are not obvious unless the kidneys are severely damaged (up to about 15 percent of your normal capacity), you should regularly examine your kidney function (especially if you suffer from heart disease Y diabetes). Here are some kidney function tests that can determine if you are at risk for kidney disease. (Read about the 12 symptoms of kidney disease that you should not ignore.)

1. Blood pressure: Your kidneys perform the function of filtering blood under pressure to eliminate waste products through urine. If your blood pressure is higher than normal, it will increase the load on the kidneys and may cause kidney disease. Alternatively, a person suffering from kidney disease is also likely to have high blood pressure. Read more about medications for high blood pressure.

2. Blood creatinine test: Creatinine is a waste product produced by the muscles. It enters the bloodstream and is filtered by the kidneys to be excreted through the urine. A blood creatinine test will measure the amount of creatinine in your blood. A higher level (greater than 0.8-1.2 mg / dl in men and 0.6-0.9 mg / dl in women)) It may indicate that the kidneys are not functioning properly.

3. Blood urea test: Urea is a waste product filtered by the kidneys and excreted through the urine. It is produced by the decomposition of proteins. A high level of urea in the blood (more than 20-40 mg / dL) may indicate an impaired function of the kidneys.

4. Urinalysis: It is one of the kidney function tests recommended by the National Kidney Foundation (NKF). It is used to detect the presence of proteins and blood cells (RBC and WBC) in the urine. Elevated levels of protein and blood cells indicate early signs of kidney disease.

5. Urea clearance test: This test is based on a comparison between the amount of urea in the blood and the amount of urea in the urine. If the clearance of urea is below the normal range (64-99 ml / min), it may indicate that the kidneys are not functioning correctly.

6. Creatinine clearance test: A creatinine clearance test also compares the level of creatinine in the blood with creatinine in the urine to determine the rate at which the kidneys filter out creatinine. The range of altered creatinine clearance (normal range: 85-125 ml / min in men and 75-115 ml / min in women) indicates impaired renal function.

7. eGFR (estimated glomerular filtration rate): The glomerular filtration rate is the rate at which the kidneys filter the waste products from the blood. The eGFR is a value that is derived from a formula based on the amount of blood creatinine, age and gender of the person. According to the NKF, eGFR is the best estimate to determine precise renal function. The normal results of eGFR vary from 90 to 120 ml / min / 1.73 m2.

8. Kidney ultrasound test: Renal ultrasound is an imaging test that uses high-frequency ultrasonic waves to verify the shape and size of the kidneys. It can detect the blood flow to the kidneys, as well as the presence of tumors, cysts and infections around the kidneys. It also helps detect the presence of kidney stones and external damage or injury to the kidneys. Are here 7 ways you could be harming your kidneys.
