[Histonet] Powdered reagent expiration dates

[DKBoyd <@t> chs.net]

Some of our stains are very old also, about 10 years ago we wrote on a 
label on each stain; Opened prior to: with that days date and Stable.  We 
were CAP inspected many times after that and we had no problems.  Just as 
you would label your reagents you make up as Stable when there isn't an 
expiration time period.

[Histonet] Powdered reagent expiration dates






We were inspected by CAP on friday and we were cited for


ANP.21366  *Are reagents and solutions properly labeled, as applicable and
appropriate, with the following elements?*

* *

1.      *Content and quantity, concentration or titer*

2.      *Storage requirements*

3.      *Date prepared or reconstituted by laboratory*

4.      *Expiration date*

Specifically that our staining powders didn't have an expiration date
printed on the bottle. All of our reconsituted reagents which are in
use were dated with an expiration date properly though. I have always
assumed, perhaphs incorrectly, that powdered stains never expire.  We have
powders like Luxol Echt Blau, etc. that were purchased and opened over 40
years ago.    If so, then these powdered reagents have gone through CAP
inspections since the beginning and this inspector was the first one to 
find
this problem.  Is this one that we might protest?
