We compared the Abbott Toxo immunoglobulin G (IgG) and IgM IMx assays with the Sabin-Feldman dye test and an IgM enzyme-linked immunosorbent assay (ELISA) in 398 serum samples previously tested in our laboratory (retrospective group) and 1,000 ...

We compared the Abbott Toxo immunoglobulin G (IgG) and IgM IMx assays with the Sabin-Feldman dye test and an IgM enzyme-linked immunosorbent assay (ELISA) in 398 serum samples previously tested in our laboratory (retrospective group) and 1,000 consecutive serum samples, tested as they were received …

Dec 6, 2020 · The IMx ELISA, which was regarded as the arbiter of true positivity, yielded a sensitivity and specificity of 99.9 percent and 100 percent respectively, for the Olympus PK™ CMV system. Forty percent of 1,807 random blood donors in this region had antibodies to CMV.

Background: Two novel enzyme linked immunosorbent assays (ELISA) (Abbott IMx CMV IgM 2.0, and Cobas Core CMV IgM EIA recomb, research version) which use recombinant antigens to detect cytomegalovirus (CMV)-specific IgM antibodies were evaluated.

For an evaluation of the Abbott Imx Toxo IgG second generation, antibodies to Toxoplasma gondii were detected by Abbott Imx Toxo IgG and IgM, Vidas Toxo IgG and Toxo IgM (bioMérieux, France) with immunofluorescence assay verified by the dye‐test for IgG, and immunosorbent agglutination assay (ISAGA) for IgM as references. The study included ...

Plasma FK506 concentrations are currently measured at the University of Pittsburgh Medical Center by an enzyme-linked immunosorbent assay (ELISA) method after a solid phase extraction (5, 6).

Nov 1, 1993 · This study validates the use of the automated IMX system and allows the comparison of IMX results with previous 'semi-quantitive' ELISA results when longitudinally assessing patients response to a recombinant hepatitis B vaccine.

The IMx ELISA, which was regarded as the arbiter of true positivity, yielded a sensitivity and specificity of 99.9 percent and 100 percent respectively, for the Olympus PK CMV system. Forty percent of 1,807 random blood donors in this region bad antibodies to CMV.

Oct 1, 1996 · We compared the Abbott Toxo immunoglobulin G (IgG) and IgM IMx assays with the Sabin-Feldman dye test and an IgM enzyme-linked immunosorbent assay (ELISA) in 398 serum samples previously tested in our laboratory (retrospective group) and 1,000 consecutive serum samples, tested as they were received in our laboratory in 1995 (prospective group).

An automated microparticle enzyme immunoassay (IMx Rubella IgG Antibody Assay; Abbott Laboratories, North Chicago, Ill.) was compared with a conventional enzyme-linked immunosorbent assay (ELISA) for detection of rubella-specific immunoglobulin G (IgG) in 400 consecutive antenatal patients.
