Alternative names:

Urine - citric acid test

Definition:

A test to measure the amount of citric acid in urine.

How the Test is Performed

A 24 hour urine sample is needed.
The health care provider will instruct you, if necessary, to discontinue drugs that may interfere with the test.

  • On day 1, urinate into the toilet upon arising in the morning.
  • Collect all subsequent urine (in a special container) for the next 24 hours.
  • On day 2, urinate into the container in the morning upon arising.
  • Cap the container. Keep it in the refrigerator or a cool place during the collection period. Label the container with your name, the date, the time of completion, and return it as instructed.
Infant:
Thoroughly wash the area around the urethra. Open a urine collection bag (a plastic bag with an adhesive paper on one end), and place it on your infant. For males, the entire penis can be placed in the bag and the adhesive attached to the skin. For females, the bag is placed over the labia. Place a diaper over the infant (bag and all). The infant should be checked frequently and the bag changed after the infant has urinated into the bag. For active infants, this procedure may take a couple of attempts -- lively infants can displace the bag, causing an inability to obtain the specimen. The urine is drained into the container for transport to the laboratory.

Deliver it to the laboratory or your health care provider as soon as possible upon completion.

The laboratory analyzes the specimen for the amount of citric acid present.

How to Prepare for the Test

No special preparation is necessary for this test. However, the results are influenced by your diet, and this test is typically performed while you are eating regularly. Consult your physician or health care provider for more information. If the collection is being taken from an infant, a couple of extra collection bags may be necessary.

How the Test will Feel

The test involves only normal urination, and there is no discomfort.

Why the Test is Performed

The test is used to diagnose renal tubular acidosis and evaluate kidney stone disease.
