Select medication: REMICADE® INFLECTRA® RENFLEXIS® (infliximab)(infliximab-dyyb) (infliximab-abda) PLEASE PROVIDE PRIMARY REASON FOR ORDER Our son's last Prometheus test showed a Serum Infliximab level Concentration of 32 and 0 antibodies. This test was preformed 4 weeks into a 8 week cycle. As a result of this high level, and confirmed remission, his doctor suggests extending cycle from 8 weeks to 10 weeks.

Results: At the end of the follow-up period, 52 patients had SCR. Serum infliximab and ATI were measured using a commercially available homogenous mobility shift assay (Prometheus Laboratories Inc., San Diego, CA, USA).
