[Histonet]Need input: Ink dissolved from Cassettes during processing.

[Rene J Buesa]

I think taking a photo is problematic because it needs to be a photo with enough resolution to "catch" all the numbers, time consuming and an "over kill".
As to a paper inside the cassette FOR SURE it will interfere with the flow of reagents and you will be having to deal with "unprocessed" tissues frequently.
The best way is a log as descriptive as possible (as I used to do).

Thank you!

Does anybody take a digital photo to correlate cassettes when using hand written cassettes as a back up?

Or 

Do you put a piece of paper inside the cassette as back up for hand written cassettes?

Need input so we can prevent future incidents.

Eleven years ago that happened in our laboratory in what we started to call "The Black Tuesday" (it was from Monday to Tuesday).
Thanks that we always kept all cassettes described-written in a log with the type of tissue and the number of pieces with their sizes.
Then we went through the list of cassettes that were stored in the baskets in sequential order.
That, and the cases description, allowed us to identify all the 268 cassettes.
We also informed the chief pathologist and documented it in our QC. The HT that "decided" to use a different pencil to write the cassettes was counseled.
We also instituted a check in of the pencil before writing the daily cassette load.
I sympathize with your issue, it was really a nightmare in our lab that we were fortunate enough to overcome (thanks to our chain of custody procedure).

Hi All,
 
What is the standard practice out in histology world if hand written cassette id washed away during processing?
 
Please share if you had any experience and how did you resolve this and what is your current practice.
 
 
Thank you so much!
