What's this test for?

This test is ideal if you're experiencing recurring kidney stones, especially calcium oxalate stones, or if you have a family history of a rare inherited condition called primary hyperoxaluria. It helps if you have unexplained kidney damage or calcium deposits showing up in your kidneys on imaging. This test looks for a specific compound in your urine that builds up when your body can't properly process certain natural substances.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained next to your value. If your level is elevated, next steps typically include drinking more water, cutting back on oxalate-rich foods, and retesting to confirm the pattern, while very high results paired with symptoms like severe pain or reduced urination should prompt you to seek medical care right away. You can download the full lab report from your account at any time, and if you retest later, the trends feature lets you see how your levels change over time.

What's included in this test?

This test measures 2,4-dihydroxyglutarate and creatinine in a urine sample. Creatinine helps make sure your urine sample is properly concentrated so the main result is accurate and comparable over time. Together these two values give a reliable picture of whether your body is producing excess oxalate-related compounds that could lead to kidney stones or kidney damage.

How can I naturally support healthy oxalate levels?

Drinking plenty of water throughout the day helps flush out excess oxalate before it can form crystals in your kidneys. Cutting back on high-oxalate foods like spinach, nuts, chocolate, and beets can also make a real difference. Getting enough dietary calcium with meals (not supplements) can bind oxalate in your gut before it's absorbed, and limiting excess vitamin C supplements is also helpful since your body can convert extra vitamin C into oxalate.

When will I get my results?

Results are typically ready within about 7 days of your sample being received at the lab. You'll get a notification once they're posted to your account, where you can view and download the full report.

Who should consider this test?

People who keep getting kidney stones, especially calcium oxalate stones, are good candidates for this test. It's also worth considering if you have a family member diagnosed with primary hyperoxaluria, or if imaging has shown calcium deposits in your kidneys without a clear explanation. Because this is an inherited condition, relatives of someone diagnosed with it may want to get checked too.

What symptoms indicate I may need this test?

Watch for recurring, painful kidney stones, especially if they start at a young age or keep coming back despite lifestyle changes. Blood in the urine, frequent urinary tract infections, or flank pain can also be signs worth investigating. In more advanced cases, reduced kidney function or unexplained fatigue and swelling can point to a need for this test.

What does high result mean?

A high level suggests your body may be producing too much of this oxalate-related compound, which raises your risk of forming kidney stones or damaging your kidneys over time. This can be caused by an inherited genetic condition or, less often, by diet or other health issues. If your result is high, increasing water intake, adjusting your diet, and retesting are good first steps, with urgent medical care needed if you notice severe pain, blood in urine, or very little urination.

How often should I retest?

If your first result comes back normal and you have no symptoms, you likely don't need to retest unless new symptoms appear. If your level was elevated, retesting every few months while you make dietary and hydration changes can help you track whether those changes are working. People with a confirmed family history of the condition may want to retest periodically as part of ongoing monitoring.

What should I do if my results are abnormal?

Start by increasing your water intake significantly and reducing high-oxalate foods like spinach, rhubarb, nuts, and chocolate. Retest after a few months to see if your level has improved with these changes. If your result is very high or you're having symptoms like severe pain, blood in urine, or swelling, seek medical care promptly since this can indicate a more serious underlying condition.
