Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A 24-hour urine collection is required for the Oxalate in Urine test. You will be provided with a clean container to collect all urine produced during a specific 24-hour period.
Test Time:
The results of the Oxalate in Urine (24-Hour Collection) test are typically available within a few days after submitting the urine sample.
Test Normal Range:
The normal range for oxalate levels in a 24-hour urine collection can vary depending on the laboratory. Typically, the reference range is provided in milligrams (mg) of oxalate excreted per 24 hours. Normal ranges may vary, but they are generally in the range of 20 to 40 mg/24 hours.
What is the Test?
The Oxalate in Urine test measures the amount of oxalate excreted in a 24-hour urine sample. Oxalate is a naturally occurring chemical found in many foods that the body also produces. High levels of oxalate in urine can lead to the formation of kidney stones, particularly calcium oxalate stones.
Test Procedure:
Discard the first urine voided in the morning and note the time. Collect all subsequent urine voided over the next 24 hours, including the first voiding on the following morning. Store the collected urine in the provided container, keeping it in a cool place or refrigerator during the collection period. Return the urine sample to the laboratory as instructed.
When to Take the Test:
This test is typically ordered by healthcare providers when there is a suspicion of oxalate-related kidney stone formation or when assessing the risk of recurrent kidney stones. It may also be used to monitor the effectiveness of treatments to prevent kidney stones.
Who Should Take This Test:
Individuals with a history of kidney stones, especially calcium oxalate stones, may be advised to take this test. It is also used for those with risk factors such as a family history of kidney stones or certain medical conditions.
Precautions for Exceptional Cases (Pregnancy, etc.):
Pregnant individuals can take this test, but it’s essential to notify the healthcare provider or laboratory if you are pregnant, as this can affect the interpretation of the results. Your healthcare provider will provide specific guidance if needed.
FAQs (Frequently Asked Questions):
Q1: How can I ensure an accurate 24-hour urine collection?
A: To ensure accuracy, it’s essential to collect all urine produced during the 24-hour period. Start the collection by discarding the first morning void and finish with the first void on the following morning.
Q2: Can dietary factors affect oxalate levels in urine?
A: Yes, certain foods, particularly those high in oxalates (like spinach, beets, and chocolate), can increase oxalate excretion in urine. It’s advisable to maintain a consistent diet during the collection period.
Q3: What are the risks of high oxalate levels in urine?
A: High oxalate levels in urine can contribute to the formation of kidney stones, particularly calcium oxalate stones. Kidney stones can be uncomfortable and necessitate medical attention.
Q4: How are high oxalate levels treated?
A: Treatment may involve dietary changes to reduce oxalate intake, increased fluid intake, and, in some cases, medications to decrease oxalate excretion or prevent stone formation.
Q5: Are there other tests associated with kidney stones?
A: Yes, various tests, including blood tests and imaging studies like CT scans or ultrasound, may be performed to assess kidney stone risk and diagnose kidney stones. The Oxalate in Urine test is one of several tests used to evaluate kidney stone risk factors.
