What's this test for?

This test is ideal if you're experiencing recurrent kidney stones or have been told you have high oxalate levels in your body. It's also useful if you have a digestive condition that affects fat absorption, since that can raise oxalate levels. Checking your oxalate level can help you understand a possible root cause of stone formation or other symptoms.

How should I prepare for this test?

How can I naturally support healthy oxalate levels? Cutting back on high-oxalate foods like spinach, nuts, beets, and chocolate can help lower your levels over time. Staying well hydrated and getting enough dietary calcium with meals can reduce how much oxalate your body absorbs. Some people also find it helpful to limit vitamin C supplements, since high doses can convert to oxalate in the body.

What's included in this test?

This test measures the amount of oxalate circulating in your blood. Oxalate is a natural compound that comes from food and body metabolism, and too much of it can bind with calcium to form kidney stones, so tracking it helps explain stone risk and certain metabolic issues.

What happens after I get my results?
Your results will show up in your account with your oxalate value and an explanation of what the normal range means. If your level is elevated, simple next steps include cutting back on high-oxalate foods, increasing water intake, and getting enough dietary calcium, then retesting after a few months to see if the changes helped. If your result is very high or you have severe symptoms like intense flank pain, seek medical care right away. You can download a standard lab report from your account and track your oxalate levels over time using the trends feature.
When will I get my results?
Results are typically ready within about 7 days of your blood draw. Once they're finalized, you'll be able to view them directly in your account along with an explanation of what your value means.
Who should consider this test?
Anyone with a history of calcium oxalate kidney stones or a family history of stones should consider this test. It's also worth checking if you have a digestive condition like Crohn's disease, celiac disease, or have had gastric bypass surgery, since these can raise oxalate absorption. People on high-dose vitamin C supplements or following a diet heavy in high-oxalate foods may also benefit.
What symptoms indicate I may need this test?
Sharp back or side pain, blood in your urine, and painful urination can all point to a kidney stone caused by high oxalate. Frequent, recurring stones are a strong signal to check your oxalate level. Digestive symptoms like chronic diarrhea or fat malabsorption can also be a reason to test, since they're linked to higher oxalate absorption.
What does high oxalate mean?
A high oxalate result means there's more of this compound circulating than usual, which raises your risk of it combining with calcium to form kidney stones. This can happen from eating a lot of high-oxalate foods, having a digestive condition, or in rare cases from a genetic issue with how your body processes oxalate. Cutting back on high-oxalate foods and drinking more water are practical first steps to bring levels down.
What causes high oxalate levels?
Common causes include eating large amounts of high-oxalate foods like spinach, nuts, and rhubarb, taking high-dose vitamin C supplements, or having a digestive condition that increases oxalate absorption in your gut. Being dehydrated can also concentrate oxalate in your blood and urine. In rare cases, a genetic condition can cause the body to overproduce oxalate on its own.
How often should I retest?
If you're making dietary changes to lower your oxalate, retesting every 3 to 6 months is a reasonable way to track progress. If you have a history of recurring kidney stones, checking your levels once or twice a year can help you stay ahead of new stone formation. Your retesting schedule may need to be more frequent if you have an underlying digestive condition affecting absorption.

What this means

This result is above the typical range, meaning there's more oxalate circulating than usual. Elevated oxalate raises the risk of it binding with calcium to form kidney stones. Diet, hydration, and certain digestive conditions can all contribute to a higher reading.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
