When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• Adalimumab Ab [Mass/volume] in Serum or Plasma
• Adalimumab Ab
• 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.
