Reference Values
Golimumab:
Quantitation Limit: <0.5 ug/mL
Results of 0.5 ug/mL or higher indicate 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:
Quantitation Limit: <20 ng/mL
Results of 20 or higher indicate detection of anti-Golimumab antibodies.
Cautions
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.
