The HACA portion of the test detects human anti-chimeric antibodies (HACA / antibodies to infliximab). Patients that develop HACA may experience infusion reactions and/or a reduced duration of efficacy of infliximab. The PROMETHEUS Anser IFX test is a new generation and more sensitive quantitative infliximab monitoring assay that allows healthcare providers to measure and monitor serum IFX and ATI levels anytime during therapy. Incorporating drug Simultaneously measures inﬂiximab (IFX) and antibodies to inﬂiximab (ATI) levels in serum at any time during therapy.

This test is set to be discontinued in August 2012 and replaced with an HMSA called the Anser™IFX test. The Anser IFX test is not ELISA-based and can measure antibodies to infliximab in the presence of serum infliximab, improving upon a major limitation of the ELISA method.

The presence of infliximab drug, even at concentrations well above target treatment levels (>50 μg/mL), does not interfere with the anti-infliximab antibody detection. 2016-01-22 All serum samples were analyzed for CRP, albumin, TNF, IFN-γ, IL-6, IL-8, IL-10, infliximab trough concentrations (in-house-developed ELISA) and antibodies to infliximab (HMSA, Prometheus Laboratories Inc., San Diego, CA). Primary non-response was defined as the absence of clinical improvement at week 14. Prometheus® Laboratories Inc. offers nonradiolabeled, fluid-phase HMSA tests called Anser™IFX for infliximab and Anser™ADA for adalimumab.
