Understanding Kidney Function Test

The main purpose of a kidney function test is to find out how well your kidneys are working.

A kidney function test is a blood or urine test that checks how well your kidneys are working. The kidneys remove waste products and excess fluid from the body. They also make hormones that control blood pressure, red blood cell production, and calcium levels.

Some common tests for kidney function include:

• Blood urea nitrogen (BUN) level

• Creatinine level

• Estimated Glomerular Filtration Rate (eGFR)

• Urinalysis

The main purpose of a kidney function test is to assess the level of creatinine and urea in the blood. These proteins are produced when muscle tissue is damaged, so their levels in the blood can be used to estimate how well the kidneys are filtering waste products from the blood.

The results of a kidney function test can help doctors diagnose conditions such as: renal failure, kidney infection, urinary tract infection, and dehydration. The test can also help doctors monitor people who have chronic kidney disease. Your doctor may order this test if you have a health problem that might be caused by your kidneys, such as high blood pressure, heart failure, diabetes, or an infection.

The main purpose of the kidneys is to clear wastes and toxins from the body. The kidneys also produce hormones that regulate blood pressure, red blood cell production, and calcium levels in the body. A kidney function test measures the following:

• Glomerular filtration rate (GFR) - This measures how well the kidneys are filtering wastes and toxins from the blood.

• Creatinine level - This is a waste product that is filtered out of the blood by the kidneys. A high creatinine level may indicate impaired kidney function.

• Blood urea

The kidneys remove waste products and excess fluid from the blood. They also make hormones that help regulate blood pressure, bone strength, and red blood cell production. The main purpose of a kidney function test is to find out how well your kidneys are working. The test can help doctors find and treat problems with the kidneys before they become serious. The main purpose of a kidney function test is to help diagnose and monitor renal diseases, such as chronic renal failure (CRF) and acute renal failure (ARF).

Your kidneys filter waste products and excess fluid from your blood. They also make hormones that help control blood pressure, red blood cell production, and the balance of minerals in your body. Damage or disease of the kidneys can interfere with any of these activities, leading to problems such as anaemia, high blood pressure, and bone weakness.

The kidneys filter wastes and excess water from the blood to make urine. Urine is then stored in the bladder and emptied through the urethra. The main job of the kidneys is to keep the balance of fluid and minerals (electrolytes) in the body. A kidney function test measures how much waste is in the blood and how well the kidneys are removing it. It also measures how well the kidneys are keeping electrolytes balanced. The most common type of kidney function test is a serum creatinine level. This measures the amount of creatinine in your blood. Creatinine is a by-product of muscle metabolism.

If your kidneys are not working properly, they cannot remove all the creatinine from your blood. This will cause the level of creatinine in your blood to rise. A high serum creatinine level may indicate that you have lost some kidney function.
