Our results indicate that the complexed-to-total PSA ratio performed better for classifying disease status than the free-to-total PSA ratio in the whole patient population and in the diagnostic gray zone of 2 to 10 ng./ml. In addition, plasma samples should be used to calculate the complexed-to-total and free-to-total PSA ratio.
La enfermedad tromboembólica venosa (ETV) se asocia en ocasiones con un proceso neoplásico, que puede ser clínicamente evidente cuando se diagnostica la trombosis o bien puede detectarse posteriormente. Esta asociación suele observarse sobre todo, en los pacientes con ETV que no presentan factores de riesgo conocidos para la trombosis en el momento de su diagnóstico y que integran el subgrupo de la ETV idiopática (ETVI) (1-12).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
