Subject: [Histonet] Unstained slides - how long are they good for?

Hello My Fellow Histologists,

Happy Friday Eve.

The question has come up......  How long are *unstained* slides good for?
Not for H&E but tests like IHC and molecular testing.  These slides have been cut, stored at room temperature, not sealed in anyway, and kept in a cardboard box.

Please let me know what your opinions are and what your retention policy is concerning *unstained* slides.

Thanks oodles.

Sincerely,

Paula Sicurello, HTL (ASCP)CM
