Cheryl,
Do you keep test (or patient blocks) in refrigerator?  Just curious about
your thoughts regarding having a control  block/section nicely positive for
"X" from the refrigerator stained next to a test section/block for "X" that
has been stored at room temp and is negative.  Would it truly be so?

Thanks,
Ray

Michelle,

We store all of our control blocks and slides in the refridgerator.
