I agree with Rene. If you are a clinical lab be sure to check any state
requirements that may exist. For example, while CAP requires 10 years,
New York State requires 20 years (at least they did when I last lived

Here, we keep blocks indefinitely (more than 20 years)

Hello histonetters,
  Due to the limited space of my lab I need to discard some blocks and
slides. I am thinking setting a "rule" about how long I can keep
paraffin blocks and slides. I need to know how other people do it. Could
you share your "rules"?
  Thanks in advance,
