[Histonet] Log sheet for cutting control slides

[Histology Technician]

Does anyone have a protocol for cutting control slides?  We are a GI lab and use patient tissue as our Gastric control for HP's and the past couple of months we've had a bad control block pulled (turned out to be colon) and had to repeat a lot.  Thought about doing a log sheet for the tech to date, sign off on, list the block # cut, and get the path to sign off on a test slide before we use that block for a control.  Any thoughts?
Thanks!
