We use Ortho IgG with our Ortho Panel. We'll probably drop the ortho panel and reagents soon and order Immucor if we need an additional panel beyond the 2 Grifols panels.
Service has gotten much better, but it was a long road getting the right people to hear and recognize a few issues. I'd be surprised if anyone else experienced similar issues moving forward and our current team is really fantastic.
Overall, the analyzer is really pretty slick. There is definitely room to grow with the reagents, but hopefully there will be big improvements next year too.
