Intended use

Infectious mononucleosis is a disease caused by Epstein-Barr virus, relatively frequent, usually harmless and often causing a high asthenia. From the earliest days of disease, heterophile antibodies of infectious mononucleosis are present in the serum in sufficient quantity to allow diagnosis. They disappear gradually but can persist up to 3 months.

These heterophile antibodies can agglutinate sheep, horse, beef and rabbit red blood cells.
ELITex Bicolor Mono is a rapid test for the detection of infectious mononucleosis heterophile antibodieswhich appear at the beginning of the disease.


ELITex Bicolor Mono is a direct agglutination slide test. The TEST LATEX consists of latex particles sensitized by erythrocytes stroma specially treated, making unnecessary the adsorption of other heterophile antibodies and ensuring the reaction specificity.

The presence of heterophile antibodies in sera is revealed by a red agglutination on a more or less intense blue background, visible to the naked eye. Otherwise, no agglutination is observed and the suspension remains homogeneous with a uniform purple color.

Handling is simple and fast. It is performed on pure serum and the results are obtained in 2 minutes.
