MARTELL, Magalys. Diagnóstico serológico de la leptospirosis humana mediante 3 variantes de la técnica de hemaglutinación pasiva. Rev Cubana Med Trop [online]. 1999, vol.51, n.1, pp.60-62. ISSN 0375-0760.

A serological study was conducted to evaluate 3 variants of the possive hemagglutination technique (HA) with the use of formalized erythrocytes of fresh lamb (HC) and of formalized Type O, Rh-negative human red blood cells (HH). No significant statistical difference were found between the results of HA and HC and between HC and HH. Unspecific reaction was only observed in 2 of the 200 sera studied by HH and HC. Heterophil antibodies were just observed in 2.5 % of the sera studied by HH, and in 100 % of the sera studied by HC. The qualitative parameters were determined for the variants used, and this way the repetition and reproducibility of the most useful variant was evaluated.
