WebMethods and devices for reducing interference from leukocytes in an analyte immunoassay are provided. In one embodiment, a method is provided comprising the steps of amending a biological sample such as a whole blood sample with one or more leukocidal reagents that reduce or eliminate the metabolic activity of leukocytes, and performing an immunoassay … WebFeb 17, 2024 · There are three main approaches to reduce the interference. The simplest means is to add a blocking agent that will bind to the heterophile antibody such as an antispecies antibody or an excess of nonspecific mouse monoclonal to compete out the HAMA or use preimmune sera.
WebResponse Feedback: In sandwich immunoassays, one particular problem is interference from circulating heterophilic human antibodies specific for animal immunoglobulins used as reagents. Heterophilic antibodies can cause false-positive results by cross-linking antibodies in a similar manner to the analyte of interest. WebHAMA, along with matrix eects needs to be addressed. A new fully synthetic sample diluent developed by Surmodics IVD allows the dramatic reduction of false positives in both in …
WebIn contrast to conventional HAMA blockers, Assay Defender® enables effective elimination of all kinds of interference and helps to prevent false positive or false negative results. Normal sandwich assay with no interference → correct result. An interfering antibody forms a bridge between capture and detection antibody → false positive result.
