Uric Acid/Creatinine Ratio (Spot Urine)

Specimen Required

Urine (Random/Spot)

Fasting Required

Purpose of the Test

The uric acid/creatinine ratio test is used to evaluate the excretion of uric acid in relation to creatinine in the urine. It is primarily used to help diagnose and monitor gout, a type of arthritis that develops when there is an excessive build-up of uric acid crystals in the joints, leading to inflammation and pain.

When this test is required

A high uric acid/creatinine ratio indicates that there is an increased excretion of uric acid in the urine, which may be a sign of gout or kidney disease. A low uric acid/creatinine ratio may indicate that the patient is not excreting enough uric acid, which can also be a sign of kidney disease.

What the Test Detects

The uric acid/creatinine ratio test measures the levels of uric acid and creatinine in a spot urine sample. The test is used to evaluate the excretion of uric acid in relation to creatinine in the urine and is primarily used to help diagnose and monitor gout, a type of arthritis that develops when there is an excessive build-up of uric acid crystals in the joints, leading to inflammation and pain.

Preparation for the Test

There is usually no specific preparation needed for the uric acid/creatinine ratio test. However, patients may be asked to avoid certain foods and medications that can affect the levels of uric acid in the body, such as alcohol, purine-rich foods, and diuretics.

Sample Requirements

The uric acid/creatinine ratio test requires a spot urine sample, which can be collected at any time of the day. The patient will be asked to urinate into a clean container provided by the healthcare provider.

Additional Notes

Certain medications and medical conditions can affect the results of the uric acid/creatinine ratio test, and patients should inform their healthcare provider of any medications, supplements, or medical conditions they have before undergoing the test. It is also important to note that the test results may be affected by factors such as diet, hydration, and exercise, and patients may be advised to avoid certain foods and activities before the test to ensure accurate results.
