I disagree, the slide is what was used to make the diagnosis. The block may not be a good representation of the actual slide, it may could have been cut so that what is on the original slide is no longer in the block. In Surgical path we keep our slides indefinitely and our blocks for 10 years.

His feeling was that they, AAVLD, leave that up to each lab depending on the state statutes regarding law suits. Our SOP says seven years on blocks and nine years on slides. I would agree with you that as long as you have blocks, the slides would be less important. Lynn Burton Lab Assoc.

It was my understanding that all paraffin blocks and stained slides need to be retained for 7 years. Others here believe that as long as the blocks are retained, it's not necessary to retain the stained slides past a year or two. Storage space might be a problem in the near future. I've looked through the AAVLD Essential Requirements, but cannot find a definitive answer to this question. Can someone help me out with the correct answer? We're writing a sample storage SOP for each lab section today, and I'd like to get an answer as soon as possible.
