What's this test for?

This test is ideal if you're experiencing symptoms related to kidney stones, unusual fatigue, or muscle weakness that may be linked to your body's acid-base balance. Citric acid levels in your blood can reflect how well your metabolism is processing energy and managing mineral balance. It's often used to help understand recurring kidney stone issues or unexplained metabolic symptoms.

What happens after I get my results?

Your results will appear in your account with a clear explanation of the normal range for citric acid and where your value falls. Depending on your result, next steps might include simple diet adjustments, staying better hydrated, or retesting after a few months to track changes. A downloadable lab report is available in your account, and you can use the trends feature to watch how your levels change over time. If your result is significantly outside the normal range, consider seeking medical care promptly.

What is Citric Acid and why does it matter?

Citric acid is a natural substance your body produces as part of energy metabolism, and it also plays a role in how your kidneys handle minerals like calcium. When citric acid levels are off, it can affect your risk of forming kidney stones or signal issues with how your body is converting food into energy. Keeping an eye on this marker helps you understand your metabolic health and stone-forming risk in a simple, measurable way.

When will I get my results?
Lab processing for this test typically takes about 7 days from the time your sample is collected. Once ready, your results are uploaded directly to your secure online account, so you can check them without waiting for a phone call. You'll be able to see your value alongside the reference range immediately.
Who should consider this test?
This test is a good fit for anyone with a history of kidney stones, ongoing unexplained fatigue, or muscle cramps that haven't been explained by other causes. It's also useful if you're curious about your metabolic health and want a baseline measurement. People tracking dietary or lifestyle changes related to kidney or metabolic health may also find it helpful.
What symptoms indicate I may need this test?
Common signs include recurring flank or back pain (a possible sign of kidney stones), unexplained muscle weakness, fatigue that doesn't improve with rest, or a personal history of stone formation. Some people also get tested simply to establish a baseline for their metabolic health. If you notice blood in your urine or severe pain, that's a sign to seek medical care right away.
How can I naturally support healthy citric acid levels?
Staying well-hydrated by drinking plenty of water throughout the day is one of the simplest ways to support healthy citric acid and mineral balance. Eating citrus fruits like lemons and oranges can naturally boost citrate levels, which may help reduce kidney stone risk. Reducing salt and animal protein intake can also help keep your metabolic balance in check. Regular movement and a balanced diet round out a solid foundation for kidney and metabolic health.
What does a low Citric Acid level mean?
A lower than normal citric acid level can be linked to a higher risk of certain types of kidney stones, since citrate normally helps prevent calcium from crystallizing in your urine. It may also reflect dietary factors, like low fruit and vegetable intake, or metabolic acid-base imbalances. Increasing water intake and eating more citrus-rich foods are simple first steps to address this.
What causes abnormal Citric Acid levels?
Diet plays a big role — low intake of fruits and vegetables, high animal protein consumption, or excess salt can all lower citrate levels. Dehydration, certain digestive conditions, and some metabolic disorders can also affect your levels. Retesting after making dietary changes can help you see if your adjustments are working.
How often should I retest?
If your first result is within the normal range and you have no symptoms, retesting once a year or as part of a general wellness check is reasonable. If you're actively working on kidney stone prevention or making dietary changes, retesting every 3 to 6 months can help you track progress. Use the trends feature in your account to compare results over time and see patterns.

What this means

Your citric acid level is below the typical range, which may be linked to a higher risk of kidney stone formation. This can often be influenced by low fruit intake, dehydration, or high salt and protein consumption. It's a useful marker to track alongside your kidney health and diet.

* 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.
