What's this test for?

This test is ideal if you're experiencing frequent nosebleeds, easy bruising, heavy menstrual periods, or prolonged bleeding after cuts, dental work, or surgery. It also helps if you have a family history of bleeding problems and want to understand whether von Willebrand Disease could be the cause. The test looks at the structure of a blood protein that helps your body form clots properly.

What's included in this test?

This test looks at the different size forms (multimers) of a key clotting protein in your blood. Analyzing these different sizes helps figure out which subtype of a bleeding disorder someone might have, which matters because different subtypes are managed differently.

What happens after I get my results?

Your results will show up in your account with each value's normal range clearly explained so you know exactly where you stand. If something looks abnormal, simple next steps might include avoiding blood-thinning medications like aspirin, watching for unusual bleeding, or retesting to confirm a pattern. If a result suggests a serious clotting problem, seek medical care right away instead of waiting. You can download a standard lab report anytime and use the trends feature to track your results over time.

How can I naturally support healthy blood clotting?

Eating foods rich in vitamin K, like leafy greens, can support your body's natural clotting process. Staying well hydrated and avoiding excessive alcohol also helps keep your blood healthy. Avoid supplements like fish oil, high-dose vitamin E, or garlic extract in large amounts since they can thin the blood further, and always check with a pharmacist before combining supplements with medications.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. This test involves specialized lab analysis of protein structures, so it takes a bit longer than routine bloodwork. You'll get a notification as soon as your results are available in your account.

Who should consider this test?

This test is a good fit for anyone with a personal or family history of unexplained bleeding or bruising. People preparing for surgery who have had bleeding complications in the past may also want this information. It's also useful if a previous basic bleeding test came back unclear and more detail is needed.

What symptoms indicate I may need this test?

Common signs include bruising easily without a clear cause, nosebleeds that are hard to stop, heavy or prolonged menstrual bleeding, and bleeding gums. Prolonged bleeding after minor cuts, tooth extractions, or childbirth can also be a signal. If these symptoms run in your family, that's another reason to consider testing.

What does an abnormal multimer pattern mean?

An abnormal pattern in the different sizes of this clotting protein can point to a specific subtype of von Willebrand Disease. Some patterns mean your body is missing the larger, more effective forms of the protein, which can make clotting less efficient. Knowing the specific pattern helps guide what kind of care might be needed if bleeding becomes a problem.

How often should I retest?

If your first result is unclear or borderline, retesting after a few weeks can help confirm the pattern, since levels can shift due to stress, illness, or hormonal changes. If you've been diagnosed with a bleeding disorder, periodic retesting can help track how it's affecting you over time, especially before major life events like surgery or pregnancy. Otherwise, this isn't a test most people need on a regular schedule.

What should I do if my results are abnormal?

If your results show an abnormal pattern, avoid medications that thin the blood, such as aspirin or ibuprofen, unless otherwise directed. Keep a record of any bleeding episodes, including how long they last and how severe they are, since this information is useful going forward. If you experience heavy, uncontrollable bleeding at any point, seek emergency medical care immediately.
