Tinción acidorresistente - Overview

Definición:

Es un examen de laboratorio que determina si una muestra de tejido, sangre u otra sustancia corporal está infectada con la bacteria que causa la tuberculosis y otras enfermedades.

Forma en que se realiza el examen:

El médico tomará una muestra de sangre, orina, materia fecal, esputo, médula ósea o tejido, dependiendo de la ubicación de la infección sospechosa.

La muestra se envía luego a un laboratorio, donde se coloca una pequeña porción sobre un portaobjetos de vidrio, se tiñe y se calienta. Las células en la muestra retienen el tinte. Luego, el miembro del equipo del laboratorio lava el portaobjetos con una solución ácida y aplica un colorante diferente.

Las bacterias que retienen el primer tinte se consideran "acidorresistentes" porque resisten el lavado ácido. Este tipo de bacterias está asociado con tuberculosis y otras infecciones.

Preparación para el examen:

La preparación depende de la forma como se recoja la muestra. El médico le explicará a la persona cómo debe prepararse.

Lo que se siente durante el examen:

El grado de molestia depende de la forma como se recoja la muestra.

Razones por las que se realiza el examen:

El examen puede establecer si la persona está infectada con micobacterias, el microorganismo que causa la tuberculosis e infecciones conexas.
