Actually, nothing on this site is the last word, however I contacted Dennis J. Ernst, MT (ASCP), Center for Phlebotomy Education, about Donna Kaiser’s 4/5/13 acid-citrate-dextrose (ACD) tube question. Dennis’s response is: “Nice to hear from you. I haven’t heard anything about the use of ACD tubes in this context. I wonder if a tube manufacturer would shed light on it. It would be interesting to hear what the coag folks at BD would say.”
Following Dennis’s suggestion, I contacted Ana Stankovic, MD, Medical Director for BD Vacutainer. Dr. Stankovic was a pathology resident at the University of Alabama at Birmingham (UAB) a few years ago. She answered, “Hi George, unfortunately, we have no data to support this. When I was at Quest, I used citrate by itself in cases of platelet clumps. I do not know if that helps. All the best, Ana.”
So the answer is there is no answer, leaving Donna or others to set up a trial to learn if ACD tubes work as well as, or better than, citrate tubes, heparinized tubes, or EDTA. The results could be helpful for us who are often confronted with platelet satellitosis. Geo.
