Hi we just got our Meditech interface for our Immucor Echo Lumena up and running and I am having problem with the ABO/Rh blood type interp not transmitting correctly. Meditech gave me the correct upload codes for the Group (ABO/Rh) channel but it transmits the value "0" as the supposedly blood type interp. We are currently on Meditech 5.6.7 build and ABO/Rh calculations were okay but i feel there is a piece of the puzzle that is missing I just can't figure what it is. I would appreciate any thoughts/ideas in helping me solve this puzzle.

Have your blood types been mapped?  The Echo sends back blood types differently than Meditech accepts them.  I believe that your Meditech instrument specialist needs to do the mapping for you.  I don't remember the exact term, but he or she should know what needs to be done.
