EPs are recordings of the nervous system’s electrical response to the stimulation of specific sensory pathways (., visual, auditory, general sensory). In tests of evoked potentials, a person’s recorded responses are displayed on an oscilloscope and analyzed on a computer that allows comparison with normal response times. Demyelination results in a slowing of response time. EPs can demonstrate lesions along specific nerve pathways whether or not the lesions are producing symptoms, thus making this test useful in confirming the diagnosis of MS. Visual evoked potentials are considered the most useful in MS.
Estas pruebas se realizan en el consultorio de un alergólogo (especialista en alergias).
Prueba de pinchazo o raspado y prueba intradérmica
Durante estas pruebas, cuya aplicación demora de 5 a 10 minutos, se introducen de 10 a 50 alérgenos. En adultos, generalmente se aplican en el antebrazo. En niños se aplican en la espalda. Después se espera unos 15 minutos para ver si aparece una pequeña protuberancia roja donde se aplicaron los alérgenos.
La prueba del pinchazo o raspado y la prueba intradérmica pueden doler un poco. Si es sensible a alguno de los alérgenos, podría tener picazón donde se le aplicó.
