IDKmonitor Adalimumab Drug Level ELISA 96 Wells


The IDKmonitor Adalimumab Drug Level ELISA kit is a microplate-based quantitative enzyme linked immunosorbent assay (ELISA) for the determination of free Adalimumab from plasma or serum samples.

The Adalimumab ELISA is based on a sandwich enzyme immunoassay technique with a Adalimumab specific capture antibody adsorbed on a microplate and a detection antibody labeled with horseradish peroxidase (HRP).

This test is intended to quantify the amount of free drug (Adalimumab) to evaluate the efficacy of drug and to investigate Primary non-response and loss of response.

Being able to stratify patients according to whether they are likely to benefit from their Adalimumab treatment has both clinical and economic advantages because not all patients respond equally to Adalimumab.

Some patients will respond well with fewer symptoms with a reduction in inflammatory biomarkers (e.g. faecal calprotectin) and endoscopic scores, while others will fail to respond during the induction phase of treatment, or lose response over time.

IDKmonitor® assays from BIOHIT HealthCare are highly specific for the target drug and are used widely for routine clinical and research applications. The IDKmonitor® Adalimumab Drug Level ELISA helps:

  • Assess risk of and manage primary non-response

  • Predict the long term outcome and identify loss of response

  • Predict response to anti-TNFα therapy withdrawal

  • Predict efficacy of re-initiating therapy after drug holiday

  • Direct the switching to Biosimilars or another class of drug

The IDKmonitor® Adalimumab Drug Level ELISA is for the quantitative determination of free therapeutic TNFα antibodies (Adalimumab (e.g. HUMIRA®)) in EDTA plasma and serum. The assay detects and quantifies free Adalimumab from a sample by capturing it using specific monoclonal anti-Adalimumab antibody that coats the plate.


The assay is well established throughout the UK and Ireland in both routine clinical laboratories as well as being used for research applications.
