Test Code ADALIMUNAB Adalimumab Concentration and Anti-Adalimumab Antibody

Performing Laboratory

LabCorp

Methodology

Electrochemiluminescence immunoassay (ECLIA)

Reference Values

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.
