What It Measures
This test measures the concentration of phylloquinone (vitamin K1) in your blood. It helps assess your vitamin K status and coagulation capacity.
Why It Matters
Vitamin K1 is critical for proper blood clotting and may play a role in bone health. Low levels can be associated with excessive bleeding and may affect bone mineral density. Consult your healthcare provider for personalised interpretation.
When to Test
Testing may be recommended if you bruise easily, experience unexplained bleeding, take blood-thinning medication, or have conditions affecting fat absorption.
