Besides creatinine, other blood and urine tests are also measures of kidney function.


Blood Tests

1. Blood Urea Nitrogen (BUN)

Urea comes from the breakdown of protein in the foods you eat.

If your kidneys are not able to remove urea from the blood, your BUN level increases.

2. Blood electrolytes

The kidneys help maintain the balance of dissolved electrolytes like #"Na"^+, "K"^+, "Cl"^"-", and "HCO"_3^"-"# in the body.

Abnormal blood levels of these electrolytes may indicate a kidney problem.

Urine Tests

1. Urine output measurements

The amount of urine you excrete in a day may indicate abnormal kidney function.

2. Dipstick analysis

A chemically treated dipstick changes colour in the presence of blood, albumin, proteins and sugar in the urine.

These can indicate compromised kidney function.
