TDMonitor Infliximab (IFX)

TDMonitor Infliximab (IFX)

Test Code 9008922
Test Name TDMonitor Infliximab (IFX)
Test Method Enzyme-linked immunosorbent assay (EIA)
Brief Description Immunoassay for the quantitative detection of infliximab and free (unbound) anti-infliximab antibodies in human serum.
Detailed Description The infliximab concentration is determined on a solid-phase capture EIA that makes use of TNFα and an infliximab-specific human monoclonal antibody.
The concentration of anti-infliximab antibodies is determined on a solid-phase bridging EIA.
Clinical Information Trough levels of infliximab and the concentration of anti-infliximab antibodies, together with clinical parameters such as disease activity, can be valuable information for patient management. The therapeutic range of infliximab has been reported at 3-7 μg/mL in inflammatory bowel disease. This range has been associated with fewer flares during the course of the treatment.

Sample Collection
Specimen Volume/Amount Container
Serum 2 mL Serum Separator Tube (SST)
Determination of infliximab trough levels is important when interpreting the concentration of anti-infliximab antibodies, i.e. when evaluating interference of the drug with the antibody test.
It is recommended to collect samples immediately before infliximab treatment, when the drug is at trough levels.
If the patient is continuously treated with courses of infliximab, it is also recommended that the sampling sequence be maintained in order to enable appropriate comparison of results.
Sample Storage

TDMonitor Adalimumab (ADL)

TDMonitor Adalimumab (ADL)

Test Code 9008923
Test Name TDMonitor Adalimumab (ADL)
Test Method Enzyme-linked immunosorbent assay (EIA)
Brief Description Immunoassay for the quantitative detection of adalimumab and free (unbound) anti-adalimumab antibodies in human serum.
Detailed Description The adalimumab concentration is determined on a solid-phase capture EIA that makes use of an adalimumab-specific human monoclonal antibody.
The concentration of anti-adalimumab antibodies is determined on a solid-phase bridging EIA.
Clinical Information Trough levels of adalimumab and the concentration of anti-adalimumab antibodies, together with clinical parameters such as disease activity, can be valuable information for patient management. Trough levels of adalimumab are higher in inflammatory bowel disease patients in clinical remission. Detection of antibodies to adalimumab predicts a lack of mucosal healing. The therapeutic range of adalimumab has been reported at 5-8 μg/mL in inflammatory bowel disease and rheumatoid arthritis.
