Common Questions


Can your pathologist evaluate a study using our software?

Yes, StageBio's pathologists can record data directly into your software, or directly into StageBio's software (Xybion Pristima® or Instem Provantis™).


Can StageBio produce digital images for pathology reports?

Yes, we can provide high resolution digital images directly from slides. Low and/or high magnification images can be generated, annotated and captioned for inclusion as an appendix of your pathology report. You provide the input regarding how many pictures are to be taken, and which diagnoses are requested for representation in the images.


Can the pathology report be formatted to my specifications?

Absolutely, StageBio can produce a report using either the format you provide or our standard format.
