Para el diagnóstico de esta enfermedad, habitualmente se utilizan tests de inmunofluorescencia que detectan inmunoglobulina G; de rutina no se dispone tests de IF para detectar inmunoglobulina M y además se necesita cultivar Bartonella henselae en células Vero para la preparación del antígeno.
En este estudio se evaluaron 84 pacientes con enfermedad por arañazo de gato definida por: contacto con gato, adenitis regional y uno o más tests confirmatorios como: PCR, test cutáneo o cultivo de B. henselae.
Es el primer estudio que se realiza en una serie de pacientes (previamente se habían publicado su uso para el diagnóstico en cases reports).
Los resultados indican que el test de ELISA podría ser una alternativa en los estudios diagnósticos de esta enfermedad.
