Infliximab and Anti-Infliximab Antibody (Serial Monitor), DoseASSURE™ IFX

Anti-TNF-alpha Drug




Infliximab and Anti-Infliximab Antibody, DoseASSURE™ IFX

Clinical Use:

Provides infliximab drug concentration levels as well as levels of anti-infliximab antibodies.

Test Information:

In the absence of anti-infliximab antibodies, the infliximab drug level typically reflects the total infliximab concentration in serum. In the presence of anti-infliximab antibodies, the infliximab drug level typically reflects the antibody-unbound fraction of infliximab concentration in serum. The presence of infliximab drug, even at concentrations well above target treatment levels (>50 μg/mL), does not interfere with the anti-infliximab antibody detection. This assay may be helpful for any patients on infliximab therapy for diseases such as Crohn’s disease, inflammatory bowel disease, ulcerative colitis, rheumatoid arthritis, or other autoimmune conditions.
