Gel is better in a way that you won't see a lot of "question mark reaction". Either it is weak pos (pos) or negative reaction. In Solid phase, we had problems grading the reactions. Having said that, you have to make your own judgement calling the strips pos/neg even though Immucor gives you a grading cut off. Basically, a lot of question mark reactions that we don't usually see in gel method. If you have any question let me know( inducing Neo). I have worked with Provue for while and I did not see as much problem as Echo Immucor Analyzer.

Yes, as far as I know Ech/Neo does not recognize Mixed field. It will flag as inconclusive result and then you will have to go and see the reaction and also the patient's transfusion history , then you will make the call as mixed field. The reaction looks like 3/4 reaction and also free cells around the 3/4 reaction. That is mixed field.
