Ordering Guidance
This test should only be ordered on patients for whom a primary diagnosis has already been established. If a patient does not have a primary diagnosis, order PATHC / Pathology Consultation or refer to the Pathology Consultation Ordering Algorithm.
If a pathology consultation is desired in addition to this test, order PATHC / Pathology Consultation alone and send the required paperwork with specimen. Indicate that amyloid protein identification is desired. If needed, this test will be added by the reviewing pathologist and will be reported with the consultation. For more information see PATHC / Pathology Consultation.
