PEREZ ELIAS, Yendrys; OBREGON FUENTES, Ana Margarita; RODRIGUEZ REYES, Isabel del Carmen  e  ALFONSO GONZALEZ, Martha Julia. Updating on the diagnosis of human leptospirosis. Rev Cub Med Mil [online]. 2015, vol.44, n.4, pp. 0-0. ISSN 1561-3046.

The human leptospirosis is zoonotic disease with worldwide distribution, frequently present a difficult diagnosis because have a wide spectrum of clinical manifestations. The objective of this work is to present an upgrade on the diagnosis of the human leptospirosis; for it was consulted it the available bibliography on the topic in the databases of Scielo, HINARI, Pubmed-Medline and different texts and articles of the last five years to deepen in the diagnosis. The microbiologic diagnostic is the base of the confirmation of the illness; it depends on the taking of sample in the appropriate moment and the correct indication of the complementary one according to the clinical phase. The observation for microscopy of dark field is not very sensitive since the leptospiras can made a mistake with poetics filaments or other devices. The etiologic agent's isolation constitutes the gold standard test; although offers a retrospective result. The polymerase chain reaction is a method used for the quick diagnosis of the infection, the quantitative variant in real time shows substantial advantages, because it allows the immediate reading and avoids the electrophoresis step, these techniques are not available for its high cost. The serologic diagnostic charges vital importance in this entity, it overcomes in speed, simplicity and low cost to the cultivation; the microagglutinación with a live antigen is considered the reference technique. The detection of IgM for enzyme linked immunobsorbent assay has been broadly used. The rapid tests based on the lateral flow immunochromatography, are a very useful variant, since they offer the result between 5 and 30 minutes.
