Definitive identification of amyloid proteins
Test ID | Reporting Name | Available Separately | Always Performed |
---|---|---|---|
MLCPC | Microdissection, Laser Capture | No | No |
MSPTC | Mass Spectrometry | No | No |
In all cases with adequate tissue, an initial Congo red stain is performed before mass spectrometry testing to confirm positivity and pattern of amyloid deposition can be considered when interpreting mass spectrometry results.
In some instances, per pathologist discretion, a different initial Congo red stain may be performed using SS2PC / Special Stain, Group II, Other (Bill Only).
-If the stain is negative for amyloid, then this test will not be performed and only the SS2PC will be charged.
-If the stain is positive for amyloid, this test will be performed and the SS2PC billing charge will be credited.
A pathology consultation is typically not required. If the amyloid subtyping results do not fit the clinical findings, a PATHC / Pathology Consultation may be added if appropriate, upon client approval.
