Testing your blood and urine can let you and your healthcare team see how your body is working. Tracking your test results over time can show you how your kidneys are doing. Here are some common tests that are done when you have CKD:. Creatinine cree-A-ti-neen is a waste you make each time you move a muscle. Those with more muscle make more creatinine.
A blood urea nitrogen BUN test measures the amount of urea nitrogen found in your blood. Urea nitrogen is a waste product made when your liver breaks down protein. It's carried in your blood, filtered out by your kidneys, and removed from your body in your urine. If your liver isn't healthy, it may not break down proteins the way it should. And if your kidneys aren't healthy, they may not properly filter urea. Either of these problems can lead to changes in the amount of urea nitrogen in your body.

What is the normal range for a creatinine blood test?
What level of creatinine indicates kidney failure ?
A common blood test, the blood urea nitrogen BUN test reveals important information about how well your kidneys and liver are working. A BUN test measures the amount of urea nitrogen that's in your blood. A BUN test can reveal whether your urea nitrogen levels are higher than normal, suggesting that your kidneys or liver may not be working properly. If kidney problems are the main concern, the creatinine levels in your blood will likely also be measured when your blood is tested for urea nitrogen levels. Creatinine is another waste product that healthy kidneys filter out of your body through urine. High levels of creatinine in your blood may be a sign of kidney damage. Your doctor may also test how well your kidneys are removing waste from the blood.
People who develop chronic kidney disease may have some or all of the following tests and measurements. If you have kidney disease ask your doctor which tests you will have and how often they will be done. Speak to your doctor about your results. If your numbers are not in the normal range, ask how to improve them. Serum Creatinine: Creatinine is a waste product in your blood that comes from muscle activity. It is normally removed from your blood by your kidneys, but when kidney function slows down, the creatinine level rises. Your doctor should use the results of your serum creatinine test to calculate your GFR.
