What's this test for?

This test is ideal if you're experiencing unexplained high blood pressure, rapid heartbeat, sweating, or anxiety-like episodes that come and go. It's also useful if you have chronic heart failure and want to understand how your body's stress hormones may be affecting your heart. Norepinephrine levels can help explain symptoms that seem tied to your nervous system's fight-or-flight response.

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. If your level is outside the normal range, the report will point you toward simple next steps, like reducing caffeine and stress, checking your blood pressure regularly, or retesting in a few months to see if the pattern continues. You can download a standard lab report anytime from your account, and if you test again in the future, the trends feature lets you see how your levels change over time. If your result comes back very high alongside severe symptoms like chest pain or a pounding heartbeat, seek medical care right away.

What symptoms indicate I may need this test?

Common signs include sudden spikes in blood pressure, a racing or pounding heart, unexplained sweating, shakiness, or anxiety attacks that seem to come out of nowhere. People with hard-to-control hypertension or existing heart failure often get this test to see if stress hormones are playing a role. If you notice these symptoms happening in episodes rather than constantly, that pattern is especially worth checking.

How can I naturally support healthy norepinephrine levels?

Regular relaxation practices like deep breathing, meditation, or yoga can help calm an overactive stress response. Cutting back on caffeine, nicotine, and alcohol also reduces unnecessary stimulation of your nervous system. Getting consistent, good-quality sleep and regular moderate exercise both help keep stress hormones balanced over time.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll receive an update as soon as your report is available in your account, so there's no need to call or follow up.

Who should consider this test?

This test is a good fit for people with hard-to-control high blood pressure, unexplained episodes of rapid heartbeat or sweating, or a diagnosis of chronic heart failure. It's also useful if you and your prior care history suggest your nervous system may be overactive. Anyone wanting a clearer picture of how stress hormones might be affecting their heart health can benefit from this test.

What is norepinephrine and why does it matter?

Norepinephrine is a hormone and nervous system chemical that helps control your blood pressure, heart rate, and your body's response to stress. When levels are consistently too high, it can put extra strain on your heart and blood vessels over time. Measuring it can help explain symptoms like unexplained hypertension or a racing heart, and it offers useful insight for people managing heart failure.

What does high norepinephrine mean?

A high result can mean your body is producing too much of this stress hormone, which may show up as high blood pressure, a fast heart rate, sweating, or anxiety. In people with heart failure, higher levels have been linked to a greater strain on the heart over time. Simple steps like managing stress, cutting stimulants, and monitoring your blood pressure at home can help, and retesting can confirm if the level was a one-time spike or an ongoing pattern.

What causes high or low norepinephrine?

High levels can be caused by chronic stress, certain medications, intense physical activity right before testing, or underlying conditions affecting the adrenal glands or nervous system. Low levels are less common but can relate to certain nerve or adrenal gland problems. Since factors like caffeine, stress, and even standing versus lying down during blood draw can affect results, it helps to follow calm, consistent conditions before testing.

How often should I retest?

If your levels are in the normal range and you feel well, you likely don't need to retest unless new symptoms appear. If your results were high or you're monitoring a condition like heart failure or hypertension, retesting every few months can help track whether lifestyle changes are making a difference. The trends feature in your account makes it easy to compare results side by side over time.
