What's this test for?

This test is ideal if you're experiencing unexplained swelling, high blood pressure, or changes in how much you urinate. It measures how much sodium your body is getting rid of over a full day, which can point to issues with your diet, kidneys, or adrenal glands. It's also useful if you've noticed symptoms of dehydration or excessive salt intake and want a clearer picture of what's going on.

What's included in this test?

This test measures the total amount of sodium your body releases through urine over a 24-hour period. Sodium levels reflect a mix of your diet, kidney function, and hormone activity, so this single measurement can offer clues about several different body systems at once.

What happens after I get my results?

Your results will show up in your account with your sodium level and the normal range clearly explained. If your level is outside the expected range, simple next steps might include adjusting your salt intake, drinking more water, or retesting in a few weeks to see if the changes made a difference. You can download the full lab report from your account anytime, and use the trends feature to track your sodium levels over time if you retest in the future. If a result looks dangerously abnormal, it's a good idea to seek medical care right away.

How can I naturally support healthy sodium balance?

Cutting back on processed foods, canned soups, and fast food can lower your sodium intake significantly since these are major hidden sources of salt. Drinking enough water throughout the day helps your kidneys regulate sodium more effectively. Eating more potassium-rich foods like bananas, spinach, and sweet potatoes can also help balance out sodium levels in your body.

When will I get my results?

Lab results for this test are typically ready within about 7 days after your sample is processed. Once ready, you'll be able to view and download them directly from your account.

Who should consider this test?

This test is a good fit for people with high blood pressure, unexplained swelling, or kidney concerns who want to understand how sodium is affecting their body. It's also useful for anyone managing a low-sodium diet who wants to confirm they're sticking to it, or for people with symptoms of adrenal gland issues like fatigue and salt cravings.

What symptoms indicate I may need this test?

Swelling in your legs or ankles, unusually high blood pressure, muscle cramps, or excessive thirst can all be signs worth checking with this test. Frequent urination or, on the flip side, very little urine output are also reasons people look into their sodium levels. Fatigue combined with salt cravings can sometimes point to adrenal gland issues that this test can help investigate.

What does high sodium in urine mean?

A high sodium result usually means you're eating more salt than your body needs, which can contribute to high blood pressure over time. It can also happen with certain kidney conditions or hormone imbalances involving the adrenal glands. Cutting back on processed and salty foods and rechecking in a few weeks is a reasonable first step.

What does low sodium in urine mean?

A low result can mean your body is holding onto sodium, which sometimes happens with a very low-salt diet, heavy sweating, vomiting, or diarrhea. It can also be linked to conditions like heart failure or certain adrenal gland problems where the body retains more sodium and water than usual. If you're experiencing severe symptoms like dizziness or rapid heartbeat alongside a low result, seek medical care.

How often should I retest?

If you're making dietary changes to manage your sodium intake, retesting every 4-6 weeks can help you see if those changes are working. If your levels were within normal range and you have no ongoing symptoms, retesting once a year or as needed is typically enough. Anyone monitoring an ongoing kidney or hormone-related condition may want to retest more frequently based on how their symptoms change.
