What it measures
- Vitamin K1 (phylloquinone) level — The main measurement; shows how much vitamin K1 is circulating in the blood.
- Prothrombin time (PT) — A clotting test often checked alongside vitamin K1 because vitamin K affects clotting.
- INR — A standardized version of PT that helps compare clotting results over time.
- Other fat-soluble vitamins — Sometimes vitamin A, D, or E are checked because they share similar absorption pathways.
- Liver-related tests — The liver stores vitamin K and makes clotting proteins, so liver markers may be included.
Preparation
No fasting is usually required for a vitamin K1 blood test. Tell your clinician about all medicines, supplements, and recent vitamin K intake, because these can affect the result.
