Oxalic Acid, 24-Hour Urine with Creatinine

What is the purpose of this test?

The Oxalic Acid, 24-Hour Urine with Creatinine test measures the levels of oxalic acid (oxalate) and creatinine in urine over a full day to evaluate kidney function and the body's oxalate metabolism. Oxalates are naturally occurring substances found in many foods and produced by the body. High oxalate levels can contribute to the formation of kidney stones and may indicate metabolic disorders, dietary imbalances, or underlying health conditions affecting the kidneys.

This test is particularly useful for diagnosing and monitoring hyperoxaluria, a condition where excess oxalates are present in the urine, increasing the risk of kidney stones and potential kidney damage. By also measuring creatinine, a waste product filtered by the kidneys, this test helps assess kidney efficiency and overall urinary function. The results can guide dietary adjustments, hydration strategies, and medical treatments to prevent kidney-related complications.

The Oxalic Acid, 24-Hour Urine with Creatinine includes:

• Oxalic Acid (Oxalate): A natural substance found in food and produced by the body; high levels can contribute to kidney stone formation and indicate metabolic imbalances.
• Creatinine: A waste product generated by muscle metabolism; its measurement helps evaluate kidney function and ensures proper urine collection during the 24-hour period.

Who should get this test?

• Individuals with a history of kidney stones or recurrent urinary tract issues.
• Those experiencing unexplained lower back or abdominal pain related to kidney function.
• People with metabolic disorders that may affect oxalate processing.
• Individuals following a high-oxalate diet or those at risk of oxalate-related health concerns.
• Patients undergoing treatment for hyperoxaluria or kidney disease who need monitoring.

When should I order the Oxalic Acid, 24-Hour Urine with Creatinine?

Individuals may consider ordering this test if they have symptoms or concerns related to kidney function and oxalate metabolism. Symptoms to consider:

• Frequent or severe kidney stones.
• Persistent lower back or abdominal pain.
• Blood in the urine or painful urination.
• Unexplained nausea, vomiting, or digestive discomfort.
• Fatigue or weakness linked to kidney function.
• History of metabolic disorders affecting oxalate levels.

If you have these symptoms or a history of kidney-related conditions, the Oxalic Acid, 24-Hour Urine with Creatinine test can provide valuable information to guide you and your doctor in diagnosing and managing your health.
