Frequently asked questions

What is the turnaround time for routine paraffin embedding, sectioning and staining? The turnaround time for most routine histology services is about one week or less. However, larger orders and orders requiring more elaborate methods may take longer.

Does the Histology Research Laboratory custom develop new techniques? Most new techniques in the Histology Laboratory are developed when a need arises and are mostly done in collaboration with the investigator requesting the new technique.

Does the Histology Research Laboratory have a biospecimen storage service? The Histology Laboratory does not have a biospecimen storage service and investigators are asked to take remaining fixed or unfixed tissue samples back to their laboratory.
