The Vitamin K1 blood test measures the concentration of phylloquinone, the primary circulating form of vitamin K obtained from dietary sources. Because vitamin K is a fat-soluble nutrient central to coagulation, this test helps evaluate whether a deficiency may be contributing to abnormal clotting or unexplained bleeding.

About Vitamin K1 Test | Vitamin Deficiency in Oakton

Vitamin K1, also called phylloquinone, is one of the two main forms of vitamin K found in the body.

Vitamin K1 is a fat-soluble vitamin absorbed from plant-based foods such as leafy greens, and it serves as a cofactor for enzymes that activate clotting factors in the liver. When levels fall, the liver cannot efficiently produce functional forms of certain clotting proteins, which can prolong the time it takes blood to clot.

The Vitamin K1 test is typically ordered when a person shows signs of a bleeding disorder, such as easy bruising, gum bleeding, or prolonged bleeding from minor cuts. It may also be used when a clinician suspects malabsorption, liver disease, or a diet inadequate in vitamin K, since these conditions can deplete phylloquinone stores.

Results are interpreted alongside other coagulation tests, such as prothrombin time, to distinguish vitamin K deficiency from other causes of impaired clotting. Because vitamin K status can be influenced by diet, medications, and underlying health conditions, the test is best understood as one part of a broader clinical picture rather than a standalone diagnosis.
