You're speaking of a Vitamin K, or Potassium, and I'm pretty sure it would affect a prothrombin and partial thromboplastin time done to see how Coumadin is doing its job. Don't trust me on this one; ask your Dr. Incidentally, did you know that before patients were given Coumadin as a blood thinner, they were given Warfarin, which is rat poison? Just a little annoying bon moit there. Don't mean to offend anyone.
