VITAMIN K

The Vitamin K test measures circulating levels of vitamin K (primarily phylloquinone/Vitamin K1) and related functional markers that reflect the vitamin's role in blood clotting and bone metabolism. It can include measurements of vitamin K1, PIVKA‑II (undercarboxylated prothrombin) and may be interpreted alongside coagulation tests such as PT/INR to assess clotting function.

This test is important for patients on vitamin K antagonists (e.g., warfarin) who require careful monitoring, for individuals with suspected malabsorption or liver disease that impairs vitamin K status, and for assessing unexplained bleeding or bruising. At‑home collection in Dubai provides convenient access to UAE‑accredited laboratory testing and timely results to support clinical decision‑making with your healthcare provider.
