Test Details
Test Name : VITAMIN K1
Alternative Test Names : PHYLLOQUINONE, PHYTOMENADIONE, PHYTONADIONE, VITAMIN K1
Code: VTK1
Test Overview : Vitamin K is a fat soluble vitamin, and requires normal fat absorption for assimilation. Vitamin K is known as the clotting vitamin, because without it blood would not clot. Deficiency of vitamin K leads to decreased concentrations of circulating, active coagulation factors, which often results in bleeding. It may be used to treat blood clotting disorders, bone metabolism disorders, and hemorrhagic disorders of newborns. Vitamin K nutritional status has been implicated in osteoporosis with some studies suggesting it helps maintain strong bones in the elderly. Methodology is Liquid chromatography/tandem mass spectrometry (LC/MS-MS) . Labcorp test code 121200.
Test Preparation Instructions : Overnight (12-hour) patient fasting is required. Consumption of supplements or food with Vitamin K may elevate plasma concentrations of Vitamin K1 for testing.
