OBJECTIVE: A novel oligoclonal band (OB) assay which consists of isoelectric focusing (IEF) and IgG immunodetection by alkaline phosphatase-labeled anti IgG antibody was reported to be very sensitive. It also accurately predicted conversion to MS in patients with CIS. The aim of our study was to compare sensitivity of a novel and the standard procedure with peroxidase immunodetection in a large number of CIS and MS patients. METHODS: OB were determined in serum and CSF samples in 161 patients (104 females), 47 with CIS and 114 with MS with median age 38 years (range 19-68) using both methods. RESULTS: Eighty-three percent of patients had CSF OB with the standard and 89% with the novel method. Median number of OB was 5 (range 0-17) with the peroxidase and 8 (range 0-18) with the alkaline phosphatase method; p=0.001. Twenty-one percent of patients had ≥10 OB with the standard and 37% with the novel method of the detection; p=0.021. Subjective impression of band clarity showed that 20% of patients had sharper and stronger bands when the peroxidase and 65% when the alkaline phosphatase method was used; p<0.0001. CONCLUSION: The alkaline phosphatase method is more sensitive than the peroxidase method and at the same time cheaper, easy to perform and less time consuming.
