In a recent article, Bas and collaborators compared different serological methods to detect chlamydial antibodies in patients with Chlamydia trachomatis infections and healthy blood donors (1). Using the Labsystems enzyme immunoassay (EIA) for C. pneumoniae, no cross-reaction between C. trachomatis and C. pneumoniae was found. However, Gnarpe and collaborators recently showed cross-reactions be...
We report a prospective evaluation of a new dot blot enzyme immunoassay (EIA) method for the direct, rapid, qualitative, simultaneous, and differential detection of the influenza A (IA) and B (IB) virus antigen in different respiratory samples. The EIA method was compared with the shell vial culture system (MDCK cell line) used with the same samples. We studied 160 samples from 93 (58.1%) pedia...
An enzyme immunoassay (EIA) was developed for detecting antibody to herpes simplex virus, and the results were compared with those of complement fixation, indirect immunofluorescent-antibody, and plaque reduction neutralization tests. Test sera showed very little nonspecific reactivity even at a starting dilution as low as 1:10. EIA results showed excellent correlation with results obtained by ...
This article presents some of the innovative practitioner experiences with environmental impact assessment (EIA) follow-up discussed at a workshop during the recent IAIA’01 conference in Colombia. Key issues raised included how EIA follow-up is initiated and who is responsible. Examples driven by proponents, regulators and the community are presented. Key points are that a focus on environmenta...
Estrogen receptor determinations have been performed on 241 cytosols from 160 breast cancer tumors using both radioactive ligands ([3H])-estradiol, [3H]R2858) and monoclonal antibodies (Abbott ER-EIA Kit) in order to compare the two methods and to evaluate the clinical usefulness of the new immunological, simplified assay. Intra- and interassay reproducibility of the enzyme immunoassay (EIA) me...
Estrogen receptor determinations have been performed on 241 cytosols from 160 breast cancer rumors using both radioactive ligands (|'II|estradiol, |3H|R2858) and monoclonal antibodies (Abbott ER-EIA Kit) in order to compare the two methods and to evaluate the clinical useful ness of the new immunological, simplified assay. Intraand interassay reproducibility of the enzyme immunoassay (EIA) meth...
The aim of this study was to investigate the clinical relevance of thoracic high-resolution computed tomography (HRCT) in evaluating the severity and outcome of Pneumocystis jirovecii pneumonia (PJP) in non-AIDS immunocompromised patients.We measured mean lung attenuation (MLA) and extent of increased attenuation (EIA) of PJP lesions on thoracic HRCT in 40 non-AIDS immunocompromised patients wi...
Supplemental assays, such as recombinant immunoblot assays (RIBA), are used to confirm detection of antibodies to hepatitis C virus (HCV). However, due to their expense, they are not widely used in developing countries. The purpose of our study was to compare the results of second- and third-generation (G2 and G3, respectively) enzyme immunoassays (EIAs) and to resolve discordant results by usi...
First pass urine (FPU) samples were compared with urethral swab culture from 304 males attending a genitourinary medicine clinic using an enzyme inmuno assay (EIA). All of the EIA positive samples were retested by incorporating a novel blocking reagent into the EIA protocol; 101 were positive by culture of which 83 were also positive by FPU EIA, an additional four were detected in FPU only and ...
