Test ID: GID2    
Autoimmune Gastrointestinal Dysmotility Evaluation, Serum

Useful For Suggests clinical disorders or settings where the test may be helpful

Investigating unexplained weight loss, early satiety, anorexia, nausea, vomiting, constipation or diarrhea in a patient with past or family history of cancer or autoimmunity

 

Directing a focused search for cancer

 

Investigating gastrointestinal symptoms that appear in the course or wake of cancer therapy, not explainable by recurrent cancer, metastasis or therapy; detection of autoantibodies on this profile helps differentiate autoimmune gastrointestinal dysmotility from the effects of chemotherapy

 

Detecting early evidence of cancer recurrence in previously seropositive patients who have a rising titer of 1 or more autoantibodies

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If immunofluorescence assay (IFA) patterns suggest collapsin response-mediator protein-5-IgG (CRMP-5-IgG), then CRMP-5-IgG Western blot is performed at an additional charge.

 

If IFA patterns suggest amphiphysin antibody, then amphiphysin titer and/or amphiphysin immunoblot is performed at an additional charge.

 

If IFA pattern suggests antineuronal nuclear antibody (ANNA)-1, then ANNA-1 immunoblot and ANNA-2 immunoblot is performed at an additional charge.

 

If IFA pattern suggests Purkinje cytoplasmic antibody (PCA)-1, then PCA-1 IFA and immunoblot is performed at an additional charge.

 

If IFA pattern suggests PCA-2 antibody, then PCA-2 IFA performed at an additional charge.

 

If IFA pattern suggests PCA-Tr antibody, then PCA-Tr IFA and immunoblot is performed at an additional charge.

 

If IFA pattern suggests N-methyl-D-aspartate (NMDA)-receptor, then NMDA- receptor cell-binding assay (CBA) and NMDA-R titer are performed at an additional charge.

 

If IFA pattern suggests alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)-receptor then AMPA-receptor CBA and AMPA-receptor titer are performed at an additional charge.

 

If IFA pattern suggests gamma-aminobutyric acid B (GABA-B)-receptor, then GABA-B-receptor CBA and GABA-B-receptor titer are performed at an additional charge.

 

If IFA pattern suggests dipeptidyl-peptidase-like protein-6 antibody (DPPX) antibody, then DPPX CBA and DPPX titer are performed at an additional charge.
