About Vitamin K1 Test | Vitamin Deficiency in Fallbrook
Vitamin K1, also known as phylloquinone, is the primary dietary form of vitamin K and a key cofactor in the coagulation cascade.
The test quantifies phylloquinone levels in a blood sample. Vitamin K1 is obtained mainly from plant sources and is absorbed with dietary fat; its concentration can therefore reflect both intake and absorption.
Vitamin K is required for the gamma-carboxylation of certain clotting proteins, including prothrombin and factors VII, IX, and X. When vitamin K1 is insufficient, these proteins remain undercarboxylated, which can impair normal clot formation.
Clinicians may order this test when a deficiency is suspected, such as in cases of fat malabsorption, prolonged antibiotic use, or inadequate dietary intake. Results are interpreted alongside the clinical picture and other laboratory findings.
