What's this test for?

This test is ideal if you're concerned about bone health, easy bruising, or whether your body is properly absorbing nutrients from your diet. It helps identify vitamin K deficiency, which can affect blood clotting, bone strength, and cardiovascular health. Many people use this test if they have digestive issues, take blood thinners, or want to ensure they're getting adequate nutrition for healthy aging.

How should I prepare for this test?

Fasting: 8 hours

You'll need to fast for at least 8 hours before your blood draw, which means no food but water is fine. Avoid eating liver and don't take multivitamins or vitamin K supplements for at least 24 hours before your test, as these can affect your results. Results typically take about 7 business days to come back.

What's included in this test?

Vitamin K

This test measures Vitamin K, which is essential for proper blood clotting and bone health. Vitamin K helps your body produce clotting factors that prevent excessive bleeding and supports proteins that strengthen your bones and may protect your cardiovascular system. Understanding your vitamin K status helps identify absorption issues and guides dietary or supplement decisions for optimal health.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your vitamin K level means for your bone health, blood clotting, and nutrient absorption. These notes include personalized recommendations like dietary changes, supplement suggestions, or lifestyle modifications to optimize your levels. You'll also get the standard lab report and can track your vitamin K levels over time using our trends feature to see how dietary changes or supplements are working.
When will I get my results?
Your results will be ready in approximately 7 business days after your blood sample is collected at the lab. You'll receive an email notification when your results are available in your secure online account, where you can view both the easy-to-understand doctor notes and your official lab report.
Who should consider getting this test?
This test is important for people with digestive disorders like Crohn's disease or celiac disease that affect nutrient absorption, those taking blood thinners like warfarin, and anyone concerned about bone health or osteoporosis risk. It's also useful for people who experience easy bruising, prolonged bleeding, or those following restrictive diets that may be low in vitamin K-rich foods like leafy greens.
What symptoms indicate I may need this test?
Consider this test if you experience easy bruising, bleeding gums, heavy menstrual periods, or if cuts take longer than usual to stop bleeding. Other signs include bone fractures from minor injuries, digestive issues that may affect nutrient absorption, or if you're on medications that might deplete vitamin K. These symptoms may indicate your body isn't maintaining adequate vitamin K levels.
How can I naturally support my vitamin K levels?
Increase your intake of vitamin K-rich foods like leafy greens (kale, spinach, collard greens), broccoli, Brussels sprouts, and fermented foods like natto and sauerkraut. Include healthy fats with your meals since vitamin K is fat-soluble and absorbs better with fats from olive oil, avocados, or nuts. Maintain good gut health with probiotics and fiber, as your gut bacteria also produce some vitamin K.
What is Vitamin K and why does it matter?
Vitamin K is a fat-soluble vitamin that plays two critical roles in your body: it helps your blood clot properly to prevent excessive bleeding, and it activates proteins that build and maintain strong bones. It's also being researched for heart health benefits. Your body can't make vitamin K on its own, so you need to get it from food or supplements, and certain conditions can interfere with absorption.
What does low vitamin K mean?
Low vitamin K levels mean your body may not have enough of this nutrient for proper blood clotting and bone health. This can lead to easy bruising, prolonged bleeding from cuts, heavy periods, and over time may contribute to weaker bones and increased fracture risk. Low levels are often caused by poor diet, malabsorption issues, certain medications, or digestive disorders that prevent your body from absorbing this fat-soluble vitamin.

What this means

Your vitamin K level is slightly below the optimal range, which may affect blood clotting efficiency and bone health over time. While this is not an emergency, maintaining adequate vitamin K is important for preventing easy bruising and supporting strong bones as you age.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
