74116-5
LaboratoryAdalimumab Ab [Mass/volume] in Serum or Plasma
Definition
This assay measures the amount of adalimumab antibodies. In the absence of anti-adalimumab antibodies, the adalimumab drug level typically reflects the total adalimumab concentration in serum. In the presence if anti-adalimumab antibodies, the adalimumab level typically reflects the antibody-unbound fraction of adalimumab concentration in serum. At drug levels of 2 ug/mL or higher, anti-adalimumab antibody quantification may be affected. However, even at adalimumab drug levels of 100 ug/mL, positive anti-adalimumab levels remain detectable.
