Nombres alternativos

Cultivo de un ganglio linfático

Definición:

Este es un examen de laboratorio realizado en un ganglio linfático para identificar microorganismos (bacterias, virus y hongos) que causan infección e inflamación de los ganglios linfáticos.

Forma en que se realiza el examen:

Se necesita una muestra de líquido del ganglio linfático. Esto se puede hacer usando una aguja para extraer el líquido (aspiración) o durante una biopsia de ganglios linfáticos.

La muestra se envía a un laboratorio donde se pone en un plato especial y se observa para ver si hay proliferación de bacterias, hongos o virus. Esto se denomina cultivo. Algunas veces, también se utilizan tintes especiales para identificar células o microorganismos específicos.

Si la aspiración con aguja no brinda una muestra lo suficientemente buena, se puede extraer todo el ganglio linfático y enviarse para realizar un cultivo y otras pruebas.

Preparación para el examen:

No se requiere ninguna preparación especial para el examen de laboratorio. Para obtener información sobre cómo prepararse para obtener la muestra del ganglio linfático, ver biopsia de ganglios linfáticos.
