A Vitamin K1 blood test measures the level of vitamin K in your blood. Vitamin K is a fat-soluble vitamin that is essential for the normal clotting of blood. It is also involved in the metabolism of bone and the synthesis of certain proteins.
The test is usually performed using a sample of blood taken from a vein in the arm.
Abnormally low levels of vitamin K in the blood (known as vitamin K deficiency) can be caused by a variety of factors, including a diet low in vitamin K, malabsorption disorders, liver disease, and certain medications. Symptoms of vitamin K deficiency may include easy bruising and bleeding, including bleeding gums, nosebleeds, and heavy menstrual periods.
Abnormally high levels of vitamin K in the blood are rare and can be caused by excessive intake of supplements or certain medical conditions. It is important to discuss any concerns about your vitamin K levels with a healthcare provider.
