All You Need To Know About Vitamin K Deficiency

When do you consider vitamin K deficiency?

Normal vitamin K levels range between 0.2 to 3.2 nanogram per milliliter (ng/ml). If the test is lower than 0.2 ng/ml means vitamin K deficiency, but bleeding disorders appear when vitamin K levels at 0.5 ng/ml or below. A blood test is rarely recommended, and it is not used for measuring vitamin K. When bleeding occurs, and vitamin K deficiency is suspected, the first option will be performing a prothrombin time (PT) test.
