What's this test for?

This test is ideal if you're experiencing unexplained swelling, fatigue, muscle cramps, or changes in blood pressure that might be tied to how your body handles salt and fluids. It's also useful if you've noticed excessive sweating, diarrhea, or symptoms that suggest your kidneys or adrenal glands aren't managing sodium properly. Because sodium levels shift with diet and time of day, this test helps clarify whether an imbalance is diet-related or a sign of something else going on.

What's included in this test?

This test measures the amount of sodium in a single urine sample, which reflects how much salt you're consuming and how well your kidneys and hormones are managing it. Sodium excretion matters because it can point to issues like dehydration, adrenal gland problems, or kidney conditions that affect fluid balance.

What happens after I get my results?

Your results will show up in your account along with the normal range so you can see exactly where your sodium level falls. If your levels are outside the expected range, simple next steps might include adjusting your salt intake, staying better hydrated, or retesting after a few weeks to see if the change was diet-related; if a result looks extreme, seek medical care promptly. You can download a standard lab report straight from your account at any time. The trends feature also lets you track your sodium levels over time to see how diet or lifestyle changes are affecting your numbers.

How can I naturally support healthy sodium balance?

Drinking enough water throughout the day helps your kidneys regulate sodium more effectively. Cutting back on processed foods, canned soups, and salty snacks is one of the easiest ways to lower excess sodium intake naturally. Eating potassium-rich foods like bananas, spinach, and sweet potatoes can also help balance sodium's effects on the body, and staying consistent with these habits over time tends to work better than short-term fixes.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. Once ready, they'll be posted directly to your online account, where you can view and download them at your convenience.

Who should consider this test?

People with symptoms like unusual swelling, high or low blood pressure, or ongoing fatigue may want to consider this test, especially if diet or hydration changes haven't helped. It's also worth considering if you have a condition like heart failure, kidney disease, or adrenal issues that can affect how your body handles salt and water.

What symptoms indicate I may need this test?

Common signs include swelling in the legs or hands, unexplained fatigue, muscle cramps or weakness, excessive thirst, or noticeable changes in urination patterns. Symptoms like severe diarrhea, heavy sweating, or unexplained blood pressure changes can also be reasons to check your sodium levels.

What does high urine sodium mean?

A higher than normal result often means you're eating more salt than your body needs, but it can also point to conditions like adrenal gland problems, kidney issues, or diabetic acidosis. Cutting back on salty foods and rechecking your levels in a few weeks is a reasonable first step. If the level stays high despite dietary changes, it may be worth exploring further, especially if you have other symptoms.

What does low urine sodium mean?

Lower than normal sodium in your urine can happen with conditions like congestive heart failure, excessive sweating, diarrhea, or a diet very low in salt. It may also occur with malabsorption issues or when your body is holding onto sodium due to dehydration. If you're experiencing symptoms like dizziness or muscle weakness alongside a low result, it's a good idea to seek medical care.

How often should I retest?

If you're making dietary changes to manage your sodium levels, retesting after 4-6 weeks can show whether those changes are working. If your levels were within a healthy range and you have no symptoms, retesting once or twice a year, or whenever new symptoms appear, is generally enough.
