Question

Which of the following tests are used to evaluate renal function?

-blood urea nitrogen and creatinine

-creatinine and amonia

-creatinine phosphokinase and blood urea nitrogen

-creatinine phosphokinase and creatinine

Answer 1

The ans is Blood urea nitrogen and creatinin test. Creatinin and amonia.

1 ) # Blood urea nitrogen ( BUN) test

# introduction (BUN)

A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine. A BUN test is done to see how well your kidneys are working.

Why Get Tested?

To evaluate the health of your kidneys; to help diagnose kidney disease; to monitor the effectiveness of dialysis and other treatments related to kidney disease or damage

2) # Creatinine Test

Your doctor may also order a creatinine test, which is another blood test that also checks your kidney health. This is because the BUN level by itself doesn’t always reveal much.

When your BUN levels are compared with your creatinine levels, it gives a fuller picture of what’s happening with your kidneys. This is known as the BUN/Creatinine ratio.

Creatinine is a waste product from your muscles that is also filtered by your kidneys. Like BUN, high levels of creatinine could mean there is a lot of waste product that hasn’t been removed by the kidneys.

The ideal ratio of BUN to creatinine falls between 10-to-1 and 20-to-1.

Having a ratio above this range could mean you may not be getting enough blood flow to your kidneys, and could have conditions such as congestive heart failure, dehydration, or gastrointestinal bleeding.

A ratio below the normal range could mean liver disease or malnutrition.

3 ) ammonia

It is most commonly used to diagnose and monitor hepatic encephalopathy, a severe liver disease

4) creatine phosphate

A Creatine Phosphokinase or CPK test determines the levels of enzymes in the blood stream. The CPK test usually administered in the following cases; To help diagnose a heart attack. To ascertain the cause of chest pain.
