What's this test for?

This test is ideal if you're experiencing hard-to-control high blood pressure, muscle weakness, cramping, or unusual fatigue that could point to a hormone imbalance. It's often used when someone has low potassium levels along with high blood pressure, since that combination can signal an adrenal gland issue. This test measures how much aldosterone your body releases over a full day, giving a fuller picture than a single blood draw.

What's included in this test?

This test measures the amount of aldosterone released in your urine over a 24-hour period. Aldosterone matters because it's the hormone that controls how your body balances sodium and potassium, which directly affects blood pressure and muscle function.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained next to your value, so you can see right away where you fall. If your aldosterone level is outside the expected range, next steps usually include reducing salt intake, reviewing potassium levels, and rechecking with follow-up testing in a few weeks to confirm the pattern. If a result looks dangerously abnormal, such as very low potassium with very high aldosterone, seek medical care promptly. You can download the full lab report anytime and use the trends feature to watch how your levels change over future tests.

How can I naturally support healthy aldosterone levels?

Cutting back on salty processed foods can help since high sodium intake pushes aldosterone production higher. Eating potassium-rich foods like bananas, leafy greens, and beans supports the sodium-potassium balance your body needs. Managing stress and getting consistent sleep also helps, since chronic stress can affect adrenal hormone output. Staying well-hydrated and limiting alcohol may further support healthy adrenal function.

When will I get my results?

Results from this 24-hour urine test are typically ready within about 7 days of the lab receiving your complete sample. You'll get a notification once your results are posted, and you can log into your account anytime to view them. Processing a 24-hour collection takes a bit longer than a standard blood test since the full urine volume needs to be measured and analyzed.

Who should consider this test?

This test is a good fit for anyone with high blood pressure that isn't responding well to standard treatment, especially if it's paired with low potassium. People with unexplained muscle weakness, cramping, or excessive thirst and urination may also benefit. It's commonly used to check for an overactive adrenal gland condition called hyperaldosteronism.

What symptoms indicate I may need this test?

Watch for symptoms like persistent high blood pressure, muscle weakness, tingling, cramps, frequent urination, or excessive thirst. Fatigue and headaches that don't have an obvious cause can also be signs worth checking. If you have both high blood pressure and low potassium found on a recent lab test, this combination is a classic reason to test aldosterone.

What does high aldosterone mean?

A high result suggests your adrenal glands may be producing too much of this hormone, which can cause your body to hold onto sodium and lose potassium. This often shows up as high blood pressure and muscle weakness or cramping. Common causes include a benign adrenal growth or both adrenal glands being overactive, and lowering salt intake while retesting is a reasonable first step.

What does low aldosterone mean?

A low result can mean your adrenal glands aren't producing enough of this hormone, which may cause low blood pressure, salt cravings, fatigue, and higher potassium levels. This pattern can sometimes point to reduced adrenal gland function. Staying hydrated and tracking your blood pressure at home can help you notice patterns, but very low readings paired with dizziness or fainting warrant prompt medical attention.

How often should I retest?

If your first result is abnormal, retesting after a few weeks is a common approach to confirm the pattern before making any bigger lifestyle changes. Once levels are back in a healthy range, checking once or twice a year is usually enough unless new symptoms appear. People actively managing blood pressure or potassium issues may want to retest more frequently to track progress.
