Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

A battery of enzyme histochemical stains or immunostains are performed; other tests can be performed as indicated and will be charged separately.  

 

Wet tissue for consultation: When adequately prepared tissue is provided, routine testing will include: PGP 9.5 immunostain, morphometric analysis, Congo red stain, and hematoxylin and eosin stain.

 

Slides and blocks sent for consultation must include PGP 9.5-reacted sections:

Special stains and studies performed on the case should be sent with the case for review. In order to determine an accurate diagnosis, some of these stains or studies may be deemed to warrant repeat testing at an additional charge at the discretion of the reviewing Mayo Clinic neuromuscular pathologist. In addition, testing requested by the referring physician (immunostains, molecular studies, etc) may not be performed if deemed unnecessary by the reviewing Mayo Clinic neuromuscular pathologist. For all consultations, ancillary testing necessary to determine a diagnosis is ordered at the discretion of the Mayo Clinic neuromuscular pathologist. An interpretation, which includes an evaluation of the specimen and determination of a diagnosis, will be provided within a formal pathology report.
