Reference Values
Adalimumab Drug Level
-Quantitation Limit: <0.6 ug/mL
Results of 0.6 or higher indicates detection of adalimumab
In the presence of anti-adalimumab antibodies, they adalimumab drug level reflects the antibody-unbound fraction of adalimumab concentration in serum.
Anti-Adalimumab Antibody
-Quantitation Limit: <25 ng/mL
Results of 25 or higher indicates detection of anti-adalimumab antibodies.
All positive antibody results are verified by confirmatory test.
<100 ng/mL Low antibody titer, no significant impact on free drug level
101 – 300 ng/mL Intermediate antibody titer, variable impact on free drug level
>301 ng/mL Hig antibody titer, significant impact on free drug level
