Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
If IFA (ANN1S/83381, ANN2S/83382, ANN3S/83137, PCABP/83383, PCAB2/83138, PCATR/83076, AMPHS/83386, CRMS/83077, AGN1S/89080) 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 is suggestive of neuromyelitis optica (NMO), NMO-IgG 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 ACh receptor binding antibody is >0.02 or if striational antibodies are > or =1:60, 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.
