Order Vitamin K1 Test | Vitamin DeficiencyThe Vitamin K1 Screen measures the concentration of phylloquinone, the primary circulating form of vitamin K, in a blood sample. Because vitamin K is a fat-soluble nutrient central to coagulation, this test is used to evaluate whether a deficiency is present and to help explain abnormal clotting findings.
About Vitamin K1 Test | Vitamin Deficiency in Normal
Vitamin K1, or phylloquinone, is the form of vitamin K obtained mainly from plant foods and is required for the liver to produce several functional clotting factors.
The test quantifies phylloquinone in serum or plasma. Vitamin K1 is absorbed with dietary fat and transported to the liver, where it serves as a cofactor for the carboxylation of clotting proteins such as prothrombin and factors VII, IX, and X.
Deficiency is uncommon in healthy adults but can arise from fat malabsorption, certain liver or biliary conditions, prolonged antibiotic use that alters gut flora, or inadequate dietary intake. Because circulating levels are sensitive to recent intake, the specimen is typically collected under conditions specified by the laboratory.
Results are interpreted alongside clinical history and other coagulation studies, such as prothrombin time. A low vitamin K1 level may support a diagnosis of deficiency, while normal results help direct attention to other causes of bleeding or clotting abnormalities.
