What this test is
This blood test measures Vitamin K1, also called phylloquinone, which is a fat-soluble vitamin needed for normal blood clotting. The test helps evaluate whether low levels might explain unusual bleeding or bruising. It is not a routine screening test and is usually ordered when there is a specific reason to check Vitamin K status.
What it measures
- Vitamin K1 (phylloquinone) — reflects the amount of this fat-soluble vitamin circulating in your blood
- Prothrombin time (PT) or INR — sometimes ordered together to assess blood clotting function
- Other fat-soluble vitamins — may be checked if malabsorption is suspected
What the test involves
The test requires a standard blood draw from a vein in your arm, usually collected into a tube that protects the sample from light. No special preparation beyond the collection lab's instructions is typically needed.
Why it is often ordered
A clinician may order this test if you have unexplained bleeding, easy bruising, or a condition that affects fat absorption, such as certain digestive disorders. It can also be used to monitor Vitamin K status in people with liver disease or those taking blood-thinning medications.
Preparation
Follow the collection lab's instructions regarding fasting, medications, or timing of the draw. Because preparation can vary, always confirm specific steps with the lab before your appointment.
How results are reported
Results are reported as a numeric value for Vitamin K1, often in nanograms per milliliter, and are interpreted alongside your symptoms and other tests. Reference ranges vary by laboratory, so your result should be discussed with your clinician in the context of the lab's own range.

Frequently asked questions
What can cause a low Vitamin K1 level?
Low levels can occur from poor dietary intake, conditions that impair fat absorption, certain medications, or liver disease. Newborns are also at higher risk because Vitamin K does not cross the placenta well. A clinician can help determine the underlying cause.
Do I need to fast before this test?
Fasting is not always required, but some labs may ask you to fast or to avoid certain foods or supplements beforehand. Always follow the specific instructions provided by the collection lab. If you take blood thinners, tell your clinician before the test.
How long does it take to get results?
Results are typically available within one to three business days, though this can vary by laboratory. Your clinician will review the results and discuss what they mean for you. Do not adjust any medication based on results without speaking to your clinician first.
Can I take Vitamin K supplements before the test?
Vitamin K supplements can affect test results, so ask your clinician whether you should pause them before the draw. Do not stop any prescribed medication without your clinician's guidance. The collection lab may also have specific instructions.
