Order Vitamin K1 Test | Vitamin DeficiencyThe Vitamin K1 Screen measures the concentration of phylloquinone in the blood. Vitamin K1 is the primary dietary form of vitamin K and is required for the synthesis of several proteins involved in coagulation. Because the body stores limited amounts of this fat-soluble vitamin, circulating levels can fall when intake or absorption is inadequate.
About Vitamin K1 Test | Vitamin Deficiency in Irvine
Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin obtained chiefly from leafy green vegetables and certain plant oils.
In the liver, vitamin K1 serves as a cofactor for the carboxylation of clotting factors II, VII, IX, and X, as well as proteins C and S. Without sufficient vitamin K, these proteins remain undercarboxylated and cannot function properly in the coagulation cascade.
A deficiency may arise from poor dietary intake, fat malabsorption conditions, prolonged use of certain antibiotics, or impaired bile flow. Because the vitamin is fat-soluble, any disorder that reduces fat absorption can lower circulating levels over time.
The Vitamin K1 Screen is typically ordered when a clinician suspects a deficiency or needs to monitor vitamin K status in a patient with unexplained bleeding or abnormal coagulation results. Results are interpreted alongside other clotting tests and clinical findings.
