When kidney functions are decreased, substances such as urea, creatinine(High Creatinine Levels), and certain electrolytes begin to build up in the bloodstream. The following blood and urine tests measure the abnormal levels of these substances in the bloodstream and can show your kidney functions.
1. Blood creatinine test. The creatinine level shows in the blood test and the doctor can know your kidney functions due to it. A high creatinine level means that your kidney functions have decreased and you need effective treatment right now. The blood creatinine level can be used to figure out the glomerular filtration rate (GFR). The doctor can use the GFR to regularly check your kidney functions and stage your kidney disease.
2. Blood urea nitrogen (BUN) test(High BUN Level). BUN test measures the amount of nitrogen in your blood that comes from the waste product urea. A BUN test is another test which shows kidney functions. If your kidneys lose the function of removing urea from the blood normally, your BUN level raises and you have to take some measures to control the disease.
3. Blood tests to measure levels of waste products and electrolytes in your blood. These substances should be removed from your blood by your kidneys. But when your kidneys are damaged, waste of products and electrolytes may be in abnormal levels.
4. Urine tests. The tests includes examines of urine protein, glucose, erythrocyte and leukocyte. In the normal condition, there are little or no these substances in urine. Kidney disease can cause the abnormal level in the urine.
It is necessary for everyone to have the tests every year, especially for those who have family members with Chronic Kidney Disease because the disease usually runs in families. If you have already diagnosed with Chronic Kidney Disease, you should do some more detailed tests, such as B ultrasound, ECT and so on.
