ABSTRACT
Nowadays technics for Helicobacter pylori detection in stools like culture, and PCR, are expensive and difficult to perform. The aim of this study was to evaluate ELISA test efficacy for detection of H. Pylori antigens in stools comparing this results with standarized technics like histology (Giemsa), ureasa test and UBT C 14. 26 patients were evaluated in this study, ages between 15-75 with upper gastrointestinal symptoms; all of them required gastroduodenal endoscopy, status H. Pylori was determined with methods upon mentioned. 24 hours after endoscopy H. Pylori antigens in stools with the technique Premier Platinum Htsa, Elisa were determined. The detection of H. Pylori antigens in stools accurately identified active H. Pylori infection. The performance characteristics of this non-invasive method was similar in sensibility and specificity to conventional tests

Se realizo la determinacion de Lp-x por la -9, 1981 y cuantitativo fue efectuado en el suero de treinta y cinco pacientes colestaticos, comparado con un grupo testigo en los que no se detecto la presencia de esta lipoproteina.Los resultados de este estudio afirman, que el hallazgo de esta lipoproteina significa un marcado avance en el diagnostico de la colestasis. Remarcamos su importancia como un metodo diagnostico superior a las pruebas bioquimicas clasicas
