RE: [Histonet] Interesting discussion about RE: timer calibration

From:"Weems, Joyce"

We already do the color blind thing, how do you not! It's in there somewhere. Doesn't it make you want to quit doing CAP?

You all are 2 fun!!! and it's only Wednesday...

Sure, why not? Require all histotechs to pass a "color-blindness" 
(note the quotes) eye exam. Given that women generally have better 
color discrimination than men in the red-green end of the spectrum, 
female histotechs should be more valuble and able to demand higher 
I can just see medical supply houses all carrying Pantone color charts ...
