Urea and Electrolytes (blood)

About this test

The Urea and Electrolytes test (U and E) is a commonly performed test to assess kidney function. The kidneys are essential for the control of the body's fluid balance. The above tests are used to investigate urinary symptoms and kidney disorders. Urea and creatinine are waste products excreted by the kidneys. Raised levels may indicate kidney damage or disease. 

Who is this test for?

This test is for individuals who wish to know how well their kidneys are functioning. The Urea and Electrolytes test is commonly performed as part of a general health check or for individulas who are taking certain medications which are known to affect kidney function. People who already have diagnosed kidney damage can also use this test ot monitor their condition.

Tests Included

Kidney Function

Sodium is both an electrolyte and a mineral. It helps regulate the water and electrolyte balance of the body and is important in the operation of nerves and muscles. Sodium levels in the blood are regulated by the kidneys. 

Excess sodium in the blood is often due to dehydration but can also indicate that the kidneys are not working properly. 

Too little sodium is often caused by fluid retention (oedema) or reflects loss due to vomiting, diarrhoea or excessive sweating. 

Chloride, like sodium, helps to maintain the balance of fluid in the body.

Raised levels can caused by eating too much salt, dehydration, diarrhoea, certain medications and also kidney disease. 

Low levels can be caused by a condition that causes the ph of the blood to be raised, chronic vomiting and over-hydration.

Urea is waste product produced as the body digests protein and is carried by the blood to the kidneys, which filter the urea out of the blood and into the urine. The urea test examines how well the kidneys are functioning.

Raised levels of urea in the blood can be caused by dehydration or high protein consumption or may indicate that the kidneys are not working properly. 

Low amounts of urea in the blood may indicate a low protein diet, excess hydration, malnutrition or liver failure. 

Creatinine is a chemical waste molecule that is generated from muscle metabolism. Measurement of this is an indicator of the levels of other waste products in the body. Creatinine is an accurate marker of kidney function.

Elevated creatinine can be caused by high intake of animal protein, taking creatine supplements and vigorous exercise but can also indicate that the kidneys are not working properly.

Low creatinine can be caused by a low protein diet, reduced muscle mass or sometime that the kidneys are simply functioning efficiently.
