Dr. Cartun is absolutely correct in always trying to use positive tissue that has been processed in your lab using the same process as your patient tissues.
The control blocks offered through the Michigan society have been donated by various laboratories in the state, and have been tested prior to donation. Before mailing a control block, that block is cut and tested again, and the slide accompanies the block to the recipient. When I donate a block to the society to be used for IHC, I supply the information of what type of fixative and how long it remained in it prior to processing as this can be critical to IHC. With all due respect, these controls are only offered as an alternative to those who have trouble locating/budget constrictions.

You can use biopsy tissue as well, but I would be careful to not cut-through the tissue in case retrospective testing is ordered. You should always try to use tissue that is fixed and processed in your own laboratory. Richard Richard W.
