have had several tia-s recently. on c less than 1 month, my lab results were 1.4,1.6, and yesterday 1.5. doctor is increasing coumadin to 4mg. effect today, is there a way to increase my lab results so that it increases to at least 2. or does increase depend on coumadin and not the food i eat? im trying to eat foods in "coumadin cookbook" so that i dont consume high vit k im totally confused thanks in advance..
