So, my recent 2yr follow-up blood work came back with a Vit K level listed as 357 on the portal. It wasn't back at the time of my physical visit and I don't have a hard copy. This is not the same reference levels I have seen before so I have no idea whether it's low or not. My PT time has also gone up and is now high at 13.6 For as far back as its been tested, I've sat at 11.5 I only question this since I'm 3 weeks away from major plastics and even during my DS surgery, Dr. Boyce needed to reverse the Heparin shot he gave me. I also did not receive any further blood thinner shots following surgery. Can anyone tell me what the reference range would be? I have used Google but can only find the same references I've always been given. My last test seemed low at .39 and that was down from .56 that was only six moths ago. I don't know how to proceed with supplementation to get me to a safe surgery zone and no one is returning my call from their office.
