When we receive pathology report for data entry, we usually review this to determine it matches the slide available before the information goes through the data entry step. If we therefore find that an OCT.specimen has a diagnosis that does not correlate to the received participant information (for example we have tumor size 1.0 cm or greater; while OCT diagnosis – no tumor seen) the OCT block will be tracked and retrieved for re-evaluation. Deeper sections will becut for a second review. A record is kept of all the samples that we consider for deeper sections. This record shows the information received, along with the diagnosis of the first evaluation of the H&E slide. After the second evaluation is performed, the information is added to the record. 
This re-evaluation process, as we call it, has been very helpful. The deeper cuts, in some cases, have revealed tumors making these samples suitable for certain research protocols thus increasing the number of material in our tissue bank that can be utilized for research. This is always something that the research scientsist are happy about!
