Reference Range
The sample was processed at Quest Diagnostics for technical-only immunohistochemistry staining as requested by the referring physician. The proper positive and negative controls were confirmed by a Quest Diagnostics pathologist(s) (see attached images), but staining of the test sample has not been evaluated by the Quest Diagnostics pathologist. Proper interpretation requires proper integration of clinical, morphologic, and immunologic information as well as proper staining and antibody selection. Fixation and processing of the tissue may interfere with the staining.
