I am needing some help setting  up electronic crossmatch in Meditech. I have everything else in place but can not figure out how to prevent EXM in patients who have mixed field reactions. I am wanting to be able to perform the IS serologically as I understand this is needed per CAP and FDA regulations. Has anyone else experience this. We are currently on version 6.08. Thanks in advance!

To prevent Meditech from qualifying a patient for EXM when mixed-field agglutination is detected, then detection of a mixed-field result must be entered into Meditech in some manner. In this way, Meditech can react to that test result using rules, reflexing tests, calculations and interpretations.

Currently, if mixed-field agglutination is detected in the Anti-A, Anti-B, Anti-A,B and/or Anti-D test, how is that mixed-field test result entered into Meditech? 

What is your current policy for documenting selection of blood for transfusion in Meditech when mixed-field agglutination is detected in ABO/Rh grouping tests?  For example, do you automatically select group O when mixed-field is detected in ABO grouping? Rh negative when mixed-field is detected in Rh grouping?

How is your Crossmatch test configured?

Do you use a Meditech Blood Issue routine in real-time when releasing blood to Nursing, et al?

Do you have a dictionary build how to bill for EXM?\

You will need to go to the BBK History desktop and then to Replace XM Test. Under it you will need to enter the history record number and put a Y in the Exclude from Electronic Crossmatch. Their are of course steps in LIS and BBK parameters but the billing is on this page below.
