Quick answer

The Vitamin K1 test measures phylloquinone in the blood. Vitamin K is a fat-soluble vitamin needed for normal blood clotting and for proteins involved in bone health. The test is typically ordered when a deficiency is suspected because of poor dietary intake, fat malabsorption, or a condition that affects how the body uses vitamin K. A healthcare provider interprets the result with the broader clinical picture.

About this test in Angwin

Vitamin K comes in several forms. Vitamin K1, or phylloquinone, is the form found in green leafy vegetables and some plant oils, while vitamin K2 refers to a group of related compounds. The body uses vitamin K to activate several clotting factors made in the liver, and it also supports proteins that help regulate calcium in bone.

The test uses a blood sample, usually collected from a vein in the arm. Laboratories measure phylloquinone directly, and results are compared with reference ranges that can vary between laboratories. Because vitamin K is fat-soluble, conditions that reduce fat absorption can lower levels, so clinicians often interpret the result alongside other fat-soluble vitamin tests.

Testing may be considered for people with unexplained bruising or bleeding, chronic liver or bile duct conditions, or malabsorption disorders such as celiac disease or cystic fibrosis. It may also be used to assess nutritional status during long-term intravenous nutrition. Results alone do not diagnose a condition and are reviewed with a qualified healthcare provider.
