Clinical and Interpretive info

  

Adalimumab drug level:

Quantitation limit: <0.6 μg/mL

Results ≥0.6 μg/mL indicate detection of adalimumab.

In the presence of antiadalimumab antibody, the adalimumab drug level reflects the antibody-unbound fraction of adalimumab concentration in serum.

Antiadalimumab antibody:

Quantitation limit: <25 ng/mL

Results ≥25 ng/mL indicate detection of adalimumab antibody
