To avoid referring immunocompromised pwMS to the laboratory, an experienced mobile phlebotomist was sent to obtain and bring back samples from the participants of the DMT-exposed cohort at their own houses. The phlebotomist was further instructed to follow strict preventive protocols and to obtain the samples as quickly as possible, to ensure the least direct contact with the immunocompromised pwMS. As mentioned, the participants of the UX cohort underwent phlebotomy at the laboratory before being included in the study. All samples included five milliliters of blood, which were used to prepare sera and stored at −20 °C until further analyses were run.
