[Histonet] AAVLD Histo sample block & slide retention policy

[Konni Black]

CLIA (feds) require blocks to be retained 2 years and slides to be retained 
10 years. Space usually determines how long beyond that they are kept. We 
keep a "Cancer" file of slides and blocks that are retained indefinitely.
