[Histonet] Ventana immunostainer

[Paula Wilder]

Our institution is trying the new Ventana immunostainer.  We have had the 
unit since July and everything was staining nicely.  Then we started to get 
variable staining, especially with CK20, ER and PR, ki67.  Ventana reps have 
been working diligently to get this problem resolved.  We are using 
pre-dilutes and the staining seems to be fine the first time, then 
increasingly variable.  The reps took our controls to another area hospital 
and tested them there and the staining was fine; hence, the problem is with 
our machine.  I know they will replace this instrument if it continues to 
fail, but I was wondering if anyone out there has similar problems.  Thanks 
for any help!
