What's this test for?

This test is ideal if you're experiencing unusual bruising, frequent nosebleeds, heavy menstrual periods, or prolonged bleeding after cuts, dental work, or surgery. It helps identify von Willebrand disease (VWD), the most common inherited bleeding disorder, and figures out which subtype you may have. It's also useful if you have a family history of bleeding problems and want to understand your own risk.

What's included in this test?

This panel measures how much von Willebrand factor (VWF) you have, how well it works to help blood clot, and how well factor VIII (another clotting protein) is functioning. It also includes a detailed look at VWF's molecular structure, which helps pinpoint the exact subtype of von Willebrand disease if one is present. Together these results give a full picture of your blood's clotting ability.

What happens after I get my results?

Your results will show up in your account with each value's normal range clearly explained. If your levels point to a bleeding disorder, next steps typically include retesting to confirm the pattern and being mindful before surgeries or dental procedures, since these carry higher bleeding risk. If any result is dangerously abnormal, seek medical care right away. You can download the full lab report anytime, and the trends feature lets you track your results over time if you retest later.

How should I naturally support healthy blood clotting?

Eating foods rich in vitamin K, like leafy greens, supports normal clotting function. Staying well hydrated and avoiding excess alcohol also helps your blood clot properly. If you bruise or bleed easily, avoid blood-thinning supplements like high-dose fish oil, vitamin E, or ginkgo unless discussed with a healthcare team, and always mention any bleeding tendency before surgery or dental work.

When will I get my results?

Results are typically ready within about 7 days after your sample is collected. Because this panel involves several specialized clotting tests, it takes a bit longer than a standard blood test. You'll get a notification as soon as your results are posted to your account.

Who should consider this test?

This test is a good fit for anyone with a personal or family history of easy bruising, frequent nosebleeds, heavy periods, or excessive bleeding after injury or surgery. It's also worth considering if a close relative has been diagnosed with von Willebrand disease. People preparing for a surgery or major dental procedure who have a bleeding history may also want this panel.

What symptoms indicate I may need this test?

Common signs include bruising easily without a clear reason, nosebleeds that are hard to stop, heavy or prolonged menstrual bleeding, and bleeding gums after brushing or dental cleanings. Prolonged bleeding after minor cuts, surgery, or childbirth can also be a clue. If several of these sound familiar, especially alongside a family history of bleeding issues, this test can help clarify what's going on.

What does low von Willebrand factor mean?

A low VWF result often means your blood may take longer to clot, which raises your chances of prolonged bleeding after an injury, surgery, or dental work. This is the hallmark of von Willebrand disease. Simple steps like informing any provider of your results before procedures and avoiding blood-thinning medications like aspirin can lower your risk of excess bleeding.

What causes low von Willebrand factor levels?

Low VWF is usually inherited, meaning it runs in families and is present from birth. In some cases, it can also develop later in life due to other health conditions, such as thyroid problems, certain blood disorders, or heart valve issues. Genetics and family history are the biggest factors, which is why family bleeding history is so important to know.

What should I do if my results are abnormal?

If your results suggest von Willebrand disease, retesting can help confirm the finding since VWF levels can fluctuate with stress, illness, or hormones. Keep a record of any bleeding episodes to share when discussing your results, and avoid medications that thin the blood, like aspirin or ibuprofen, unless necessary. Let anyone performing surgery or dental work know about your results ahead of time.
