There was one additional patient with an indeterminate result around the ARUP NMDA CSF test. Two of the patients for the ARUP VGCC serum test experienced both indeterminate and positive results at numerous timepoints. There were 12 patients with indeterminate results for the Amsacrine hydrochloride ARUP VGKC test.

From your paraneoplastic serum panel from Mayo, autoantibodies to striational antibodies (38/483, 7.9%) and VGKC (20/483, 4.1%) were the most common detected. Fig.?1 summarizes a breakdown of screening for the Mayo serum paraneoplastic autoantibody panel, with results classified into four groups: (a) one or more positive results around the panel in a patient with known or later discovered malignancy, (b) negative results around the panel in a patient with known or later discovered malignancy, (c) a number of positive results in the -panel for an individual with out a known malignancy, and (d) bad results in the -panel for an individual with out a known malignancy.
