Exhausted, I am not familiar with your husbands case at all so I will just add what I can. If you have a specialist treating your husband now then that DR can call Vanderbilt and speak to someone there directly. A Dr to Dr call is always helpful and usually cuts through the red tape a little. You may want to ask his Dr to do it as soon as possible. I know 5 weeks seems like a lifetime to you but in reality (medically speaking from the hospitals standpoint) it's not that long. You are correct in assuming that a lot can change in 5 weeks though. I would persue the possibility of his Dr making the call. I also agree with hep93. There may be a patient advocate that is available at Vanderbilt that you can speak to. As far as testing his son-that has to be ordered by Vanderbilt. As far as I know nothing can be done until there is a Doctors order for it. That too takes time. I hope this helped a little.
