[Histonet] Frozen Tissue Retention

[Bradley, Joshua, D]

I am curious as to the frozen tissue retention policies in other institutions, especially in children's facilities.  How long are samples considered diagnostically viable and relevant to patient care?  What is done with the tissue when the time limit is reached?

Our facility is interested in using old samples in research applications (unidentified of course).  We currently have a retention policy of 10 years, but wanted to gauge how other facilities approach this matter.

Thanks for any help that can be provided.
