Special Instructions
Not provided.
Limitations
This test does not include pathologist interpretation, only technical performance of the stain. Interpretation should be performed in the context of the patient's clinical history and other diagnostic tests by a qualified pathologist. Age of a cut paraffin section can affect immunoreactivity. Stability thresholds vary widely among published literature and are antigen dependent. Best practice is for paraffin sections to be cut within 6 weeks. Sending unsuitable glass slides can result in inconsistent staining.
