‹ Back to Hematology index

Secondary ID A test code used for billing and in test definitions created prior to November 2011


NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.


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

Serological evaluation of patients who present with a subacute neurological disorder of undetermined etiology, especially those with known risk factors for cancer


Directing a focused search for cancer


Investigating neurological symptoms that appear in the course of, or after, cancer therapy, and are not explainable by metastasis


Differentiating autoimmune neuropathies from neurotoxic effects of chemotherapy


Monitoring the immune response of seropositive patients in the course of cancer therapy


Detecting early evidence of cancer recurrence in previously seropositive patients

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 situation(s) when tests are added to the initial order. This includes reflex and additional tests.

If IFA (ANN1S, ANN2S, ANN3S, PCABP, PCAB2, PCATR, AMPHS, CRMS, AGN1S) patterns are indeterminate, paraneoplastic autoantibody Western blot is performed at an additional charge.

If client requests or if IFA patterns suggest CRMP-5-IgG, CRMP-5-IgG Western blot is performed at an additional charge.

If IFA pattern suggest NMO/AQP4-IgG, NMO/AQP4-IgG CBA is performed at an additional charge.

If IFA patterns suggest amphiphysin antibody, amphiphysin Western blot is performed at an additional charge.

If IFA patterns suggest GAD65 antibody, GAD65 antibody radioimmunoassay is performed at an additional charge.

If IFA pattern suggest NMDA-R, NMDA-R Ab CBA and/or NMDA-R Ab IF Titer Assay is performed at an additional charge.

If IFA pattern suggest AMPA-R, AMPA-R Ab CBA and/or AMPA-R Ab IF Titer Assay is performed at an additional charge.

If IFA pattern suggest GABA-B-R, GABA-B-R Ab CBA and/or GABA-B-R Ab IF Titer Assay is performed at an additional charge.

If ACh receptor binding antibody is >0.02, ACh receptor modulating antibodies and CRMP-5-IgG Western blot are performed at an additional charge.

CRMP-5-IgG Western blot is also performed by specific request for more sensitive detection of CRMP-5-IgG. Testing should be requested in cases of subacute basal ganglionic disorders (chorea, Parkinsonism), cranial neuropathies (especially loss of vision, taste, or smell) and myelopathies.
