Recommendations for useful serum testing with suspected multiple sclerosis

Abstract

Several practical questions useful for management of patients with multiple sclerosis remain unanswered in the current scientific literature. Decisions are often made individually, without the support of solid scientific evidence. In order to facilitate concurring practices, we present guidelines concerning useful serum exams for the diagnosis of multiple sclerosis. The methodology used was that of a formal expert consensus. A working group performed a systematic analysis of the literature, taking into account both previously existing recommendations and original articles, and then drafted guideline proposals. These proposals were subjected to the critical review of a rating group. Three written drafts, followed by rating of the guideline proposals culminated in a consensual document, which was submitted for review to a second independent reading group. The final resulting document provided the material for the present article, in which each recommendation is presented with its grade according to the level of proof or its degree of consensus in the absence of scientific proof.
