About this Test:
The 24-Hour Urine Oxalate test measures the total amount of oxalate excreted in your urine over a full 24-hour period. Oxalate is a natural chemical found in many foods and is also produced by the body. High levels of oxalate in the urine (Hyperoxaluria) are a major risk factor for the formation of calcium oxalate kidney stones.
✔ The primary test for diagnosing Hyperoxaluria.
✔ Essential for investigating the cause of recurrent kidney stones.
✔ Helps differentiate between genetic causes (Primary Hyperoxaluria) and dietary/intestinal causes.
✔ Requires a strict 24-hour urine collection protocol.

Oxalate and Kidney Stones
Calcium oxalate stones are the most common type of kidney stone. They form when oxalate binds with calcium in the urine, creating hard crystals. Measuring the amount of oxalate in a 24-hour urine sample is crucial for identifying the root cause of stone formation.
Causes of High Urine Oxalate
- Dietary Excess: Consuming large amounts of high-oxalate foods like spinach, rhubarb, beets, nuts, and chocolate.
- Malabsorption (Enteric Hyperoxaluria): Conditions like Crohn's disease, celiac disease, or gastric bypass surgery can increase the absorption of oxalate from the gut.
- Primary Hyperoxaluria: A rare, genetic disorder where the liver produces too much oxalate. This can lead to kidney failure if not managed.
Collection Instructions
Accurate results depend on proper collection:
- Start: Empty your bladder into the toilet at a set time (e.g., 8 AM). Do not collect this.
- Collect: Collect every drop of urine for the next 24 hours in the container provided.
- End: At the same time the next day (e.g., 8 AM), empty your bladder into the container. This is the last sample.
- Acid Preservative: Some labs require an acid preservative in the container. Please check with the lab staff when picking up the container.
Frequently Asked Questions (FAQ)
Q1: Why is the 24-hour urine oxalate test performed?
It is primarily performed to determine the cause of recurrent kidney stones. High levels of oxalate in the urine significantly increase the risk of forming calcium oxalate stones.

Q2: What foods are high in oxalate?
Foods rich in oxalate include spinach, rhubarb, beets, nuts (especially almonds and peanuts), chocolate, tea, and wheat bran. Your doctor may ask about your diet based on the test results.

Q3: What is Hyperoxaluria?
Hyperoxaluria is a condition characterized by excessive oxalate in the urine. It can be caused by genetic disorders (Primary), intestinal diseases (Enteric), or a diet high in oxalate.

Q4: Do I need to follow a special diet before the test?
Usually, you should eat your normal diet during the collection period so the test reflects your typical oxalate excretion. However, follow any specific instructions given by your doctor.

Q5: Why does the report take 5 days?
Measuring oxalate requires specialized chemical analysis (often using enzymatic methods or chromatography) which is more complex than routine urine tests. This processing time ensures high accuracy.
