These thresholds are provided as a guide and a complement to your clinical judgment to help inform patient management. If you have questions or would like assistance in interpreting a Vectra DA result, please contact Crescendo Bioscience at 1-877-RHEUMDX (1-877-743-8639) to request a consultation with a member of Crescendo’s Medical Affairs Team.
Note: We encourage practices to set -up a consultation after they have had experience with Vectra DA in 25+ RA patients and/or 6 months has passed since ordering the initial Vectra DA test.
