What's this test for?

This test is ideal if you're experiencing repeated, unexplained episodes of swelling in your face, hands, feet, throat, or abdomen, especially if these episodes aren't caused by allergies and don't respond to typical allergy medicine. It also helps if hereditary angioedema runs in your family and you want to know if you carry the same genetic tendency. Getting answers can help you understand your triggers and avoid dangerous swelling episodes, particularly ones that affect breathing.

What's included in this test?

This panel looks at proteins in your blood that control swelling and inflammation in your body. Because hereditary angioedema is caused by a shortage or malfunction of one of these key proteins, measuring their levels and activity helps show whether your body's swelling-control system is working the way it should.

What happens after I get my results?

Your results will appear in your online account with each value's normal range clearly explained, so you can see exactly where you stand. If your results point to hereditary angioedema, next steps include noting your swelling patterns and triggers, and being ready to seek emergency care right away if you ever have swelling that affects your throat or breathing. Your full lab report is downloadable from your account at any time, and you can track your results over time using the trends feature if retesting is ever needed.

How can I naturally support healthy swelling control?

While hereditary angioedema itself is genetic and can't be reversed with lifestyle changes, you can help reduce flare-ups by avoiding known triggers like physical trauma, intense stress, certain medications (such as estrogen-containing birth control or ACE inhibitors), and infections. Keeping a symptom diary can help you spot patterns and avoid your personal triggers. Staying hydrated, managing stress through relaxation techniques, and getting enough sleep can also support your body's overall resilience.

When will I get my results?

Results for this panel are typically ready within about 7 days of your lab visit. You'll get a notification when they're ready to view securely in your online account, where you can also download a standard lab report for your records.

Who should consider this test?

This test is a good fit for anyone with recurring, unexplained swelling episodes that don't itch or respond to antihistamines, especially swelling of the face, throat, hands, feet, or abdomen. It's also worth considering if a close family member has been diagnosed with hereditary angioedema, since the condition is passed down genetically. People who've had a swelling episode severe enough to affect breathing should also consider getting tested.

What symptoms indicate I may need this test?

Watch for repeated swelling in the face, lips, hands, feet, genitals, or abdomen that comes on over hours and can last a few days. Unlike allergic swelling, hereditary angioedema swelling usually isn't itchy and doesn't come with hives. Severe abdominal pain, nausea, or vomiting during these episodes, or swelling in the throat that makes breathing or swallowing difficult, are also key signs worth testing for.

What does an abnormal result mean?

An abnormal result may mean your body has lower levels or reduced activity of a key protein that normally keeps swelling in check, which is the hallmark of hereditary angioedema. This doesn't mean you'll have constant symptoms, but it does mean you're more prone to swelling episodes, especially after triggers like stress, injury, or certain medications. Your lab report will explain exactly which values are outside the normal range and what that typically indicates.

What causes hereditary angioedema?

Hereditary angioedema is caused by an inherited gene change that leads to too little of a protein called C1 inhibitor, or a version of it that doesn't work properly. This protein normally helps control swelling in your blood vessels, so when it's missing or faulty, fluid can leak into tissues and cause sudden swelling. Because it's genetic, it's passed down from a parent, though in rare cases it can occur from a new gene change.

What should I do if my results are abnormal?

If your results suggest hereditary angioedema, start by tracking when your swelling episodes happen and what may have triggered them. Avoid known triggers like certain medications, excess stress, and physical trauma when possible. If you ever experience swelling in your throat or trouble breathing, seek emergency medical care immediately, since this can be life-threatening.
