[Histonet] Control Block Tracking

Tue Mar 6 12:09:58 CST 2012

I also like to use our LIMS system as a tracking tool.  In house controls have an accession number that will be on all control blocks and any out of house controls I get are accessioned into LIMS thus giving me electronic records and a case number to use on the control block.   Traceability is an AAVLD regulation.

I must disagree  - at one time we also kept a control block list - it can very easily become a record keeping nightmare.
We write the ID of the control tissue used in the data base and on the slide label - end of story.  No control block written records to update, file, access or archive.

My four cents,

Absolutely unnecessary! You have to remember that an "inspector", in order to appear knowledgeable and "demanding", has to say something, even if it is stupid.
But you can comply in a simple way (as I used to do):  make a list of your control blocks, with documentation about what antigens they are used for. Also write the dates from/to that particular block was used.
If you want to know what control was used for a specific case/antigen, just check the data the test was performed, and refer to your control blocks list to know which was use according with the date.
The problem arises when you use, for example normal tonsils, although those can also be referred to a case number (the one corresponding to the tonsil resection).
In this way you will comply without the need to add additional information to every case.

During a recent inspection of my department, the inspector "encouraged"
me to develop a method of tracking which control tissue I used for a case (i.e., individually identifying the block and referencing that identifier on the slide).  To be honest, I believe this to be overload, but since I'm probably going to have to abide by that "encouragement", I'd like to know if/how you identify which control block is used for a special stain.  I can think of a simple method but wonder if any of you have used a really spectacular method that just blew the inspecting agency away.  I'd promptly plagiarize it!  Gracias!
