Result Interpretation

See Report

   In the absence of anti-vedolizumab antibodies, the vedolizumab drug level reflects the total vedolizumab concentration. In the presence of anti-vedolizumab antibodies, the vedolizumab concentration reflects the antibody-unbound fraction of vedolizumab.
The presence of vedolizumab drug, even at concentrations well above target treatment levels , does not interfere with anti-vedolizumab antibody measurement. All positive anti-vedolizumab antibody results are verified by a confirmatory test.
Limitations
Drug half-life should be taken into consideration when interpreting concentrations measured in non-trough collections.
