What's this test for?

This test is ideal if your child has had kidney stones, or if a doctor has raised concerns about calcium buildup in the kidneys (nephrocalcinosis). It measures how much oxalate your child's body is getting rid of through urine, which helps figure out if a condition called hyperoxaluria is behind the stones or kidney issues. It's also used to keep an eye on treatment progress in children already diagnosed with this condition.

What's included in this test?

This test measures oxalic acid alongside creatinine in a urine sample. Pairing the two matters because creatinine acts as a reference point, helping account for how concentrated or diluted the urine sample is, which makes the oxalate reading more accurate and comparable over time.

What happens after I get my results?

Your child's results will show up in your account, with the normal range for oxalic acid and creatinine clearly explained so you can see where the values fall. If the numbers are outside the expected range, next steps often include dietary adjustments (like reducing high-oxalate foods) and repeat testing to track changes over time. If a result comes back significantly high, especially alongside symptoms like severe pain or blood in the urine, seek medical care right away. You can download the full lab report anytime and use the trends feature to watch how levels change over future tests.

How can I naturally support healthy oxalate levels?

Cutting back on high-oxalate foods like spinach, nuts, chocolate, and beets can make a real difference for many kids. Making sure your child drinks plenty of water throughout the day helps flush oxalates out and reduces the chance of stone formation. Pairing calcium-rich foods with meals (rather than avoiding calcium) can actually help bind oxalate in the gut before it's absorbed. Always introduce dietary changes gradually and retest to see if they're helping.

When will I get my results?

Results are typically ready within about 7 days of your child's sample being processed at the lab. You'll get a notification once they're posted to your account so you can log in and review them right away.

Who should consider this test?

This test is a good fit for children who have developed kidney stones, show signs of calcium deposits in the kidneys, or have a family history of primary hyperoxaluria. It's also useful for kids with digestive conditions like inflammatory bowel disease or those who've had bowel surgery, since these can raise oxalate levels indirectly.

What symptoms indicate my child may need this test?

Watch for signs like abdominal or back pain, blood in the urine, frequent urinary tract infections, or passing visible stones. Unexplained kidney problems showing up on imaging, or a family history of early kidney disease, are also good reasons to consider this test. If your child has any digestive disorder affecting fat absorption, that's another signal worth discussing.

What is hyperoxaluria and why does it matter?

Hyperoxaluria means the body is excreting too much oxalate, a natural substance found in many foods that humans can't break down and must pass through urine. When there's too much of it, oxalate can combine with calcium to form painful kidney stones or, over time, damage the kidneys. Catching it early matters because untreated hyperoxaluria can progress to serious, lasting kidney problems.

What does a high oxalic acid result mean?

A high result means your child's body is releasing more oxalate than expected, which raises the risk of kidney stones or kidney damage over time. This can be due to diet, digestive issues affecting fat absorption, or in rarer cases, an inherited enzyme problem. Simple first steps include reviewing your child's diet for high-oxalate foods and increasing fluid intake, then retesting to see if levels improve.

How often should retesting happen?

For children being monitored after a diagnosis or treatment change, retesting every few months is common to track progress. If dietary changes were just introduced, waiting about 4-8 weeks before retesting gives a clearer picture of whether they're working. Your family's specific retest schedule may vary based on how the first results looked.
