This Vitamin K Test is used to measure levels of vitamin k in the blood in order to help diagnose deficiencies. Vitamin K is required for proper blood clotting and low levels can increase your risk of uncontrolled bleeding. Those with a vitamin K deficiency are more prone to bruising and osteoporosis. Green vegetables are an excellent source of vitamin K and an easy way to increase your levels if your Vitamin K Test should return lower results than typical.
Testing Method: Blood draw
Test Preparation: Fasting is required (i.e. no eating or drinking anything besides water for 8 hours prior to testing), and patient should abstain from consuming liver, multivitamins or vitamin K for a 24 hour period before testing.
