I too have been having multiple false positives with the FBS kit and have been getting the same run around from the vendor. The last thing to come up was the saline also but I check the buffered saline and I'm running a pH of 7.9. We confirm all our FBS with a KB.

immediate spin compatable but 37 and AHG incompatable? It's not sounding like an anti-I. No chance of running an AB screen? Did you run a DAT or do a prewarm? I hate doing a prewarm blind but if you can't do a screen.....
