A blood urea and serum creatinine test comprises two different tests to check the function of the kidneys. These two substances, urea and creatinine, are waste products produced as a result of the body's metabolism. Typically, urea and creatinine dissolve in the blood and your kidneys filter them and excrete them out through urine. However, in kidney disease, the levels of both these by-products will increase in the blood, as the kidneys will be unable to filter them.
Abnormal urea and creatinine levels in the blood are a sign of acute or chronic kidney disease. Your doctor will advise further tests to evaluate for the cause of this and the kind of kidney disease you might be having.
At Apollo 24|7, you can find the complete urea creatinine test price details with the procedure. A single package includes a blood urea test and a serum creatinine test. Altogether, these two tests are also called BUN creatinine tests.
Your doctor may prescribe a creatinine test and BUN test for various conditions such as:
- Unusual swelling in face, hands, legs, and abdomen
- Distinct puffiness around the eyes, especially in the upper eyelids
- Hypertension and diabetes
- Constant fatigue and sleeplessness
- Painful urination with decreased urine output
- Blood in Urine

Frequently Asked Questions (FAQs)
How is the blood sample taken?

The needle is then inserted into the vein in the arm and the blood sample is collected in the vacutainer.
What other tests can be advised along with the urea test?
