Limitations
This test does not include pathologist interpretation, only technical performance of the stain. The charge of glass slides can be affected by environmental factors, potentially altering slide staining. Staining consistency can be impacted by the age of cut paraffin sections, with stability being antigen dependent. Best practices include cutting paraffin sections within 6 weeks.
