How often are you decontaminating your NeXes machines (running
decontaminating reagents through the tubing)?

Subject: [Histonet] possible AFB contaminant
Please help, we have had an increase in demands for repeats on our AFB
stain. Our pathologists have been noticing what they believe are "false
positives" on our slides. We perform our AFBs on the Ventana Nexus and some
are done by hand. Because of this problem, we have been doing side by side
comparisons using the Nexus and hand stain.
We still have complaints. We have made new reagents, changed kits, tested
our DI water sytem and have different techs cutting using different
waterbaths.
Any advice or comments would be greatly appreciated.
Thanks Debi
