The method for laboratory diagnosis of multiple sclerosis (MS)--the loading serotonin test in vitro based on a specific type of interaction between MS patient's blood lymphocytes and serotonin--is suggested.

An examination of 56 MS patients, 12 patients with vertebrale nervous system pathology, 33 patients with MS phenocopies and 19 healthy subjects revealed an initial low serotonin rosette-forming cell (RFC) content in MS patients, comparing to all the subjects studied.

In contrast to healthy subjects and patients with other neurological disorders, serotonin receptor lymphocyte expression in MS patients does not change during serotonin stimulation in vitro and serotonin RFC number does not increase.

The type of interaction is specific and selective, being confirmed in reaction of rosette-formation by serotonin excess and by the results of rosette-formation reaction with other biologically active components (histamine, nor adrenaline).

A serotonin reception inhibition, specific for MS, can be determined already in the disease debut, regardless of patient's gender and age, clinical type, disease stage and duration, which proves to be of most importance.

The loading serotonin test indexes are significant for differential diagnosis.

The method patented in 1999 is realized in vitro, excludes a double blood collection that reduces allergy and infection danger for patients is easy to make and cost-effective.
