Test Details
Limitations
Failure of golimumab therapy may not always be due to the presence of anti-golimumab antibodies. Conversely, the absence of anti-golimumab antibodies does not guarantee response to treatment.
Methodology
Electrochemiluminescence Immunoassay
Reference Interval
Golimumab drug level: <0.5 μg/mL
• Result ≥0.5 μg/mL indicates detection of golimumab
• In the presence of serum anti-golimumab antibodies, the golimumab drug level reflects the antibody-unbound (free) fraction of golimumab in serum.
Anti-golimumab antibody: <20 ng/mL
• Result ≥20ng/mL indicates detection of anti-golimumab antibodies.
