Examen de parásitos y huevos en las heces

Definición:

Es un examen de laboratorio para determinar si una muestra de materia fecal contiene parásitos o huevos que estén asociados con infecciones intestinales.

Forma en que se realiza el examen:

Se necesita una muestra de materia fecal. Hay muchas maneras de recolectar la muestra. Usted puede recoger la materia fecal en un envoltorio plástico que se coloca suelto sobre la taza del inodoro y se sostiene en su lugar con el asiento. Luego, se coloca la muestra en un recipiente limpio.

Un equipo de recolección de la muestra para el examen viene con un papel higiénico especial que se emplea para recogerla. Luego, se coloca la muestra en un recipiente limpio.

Para recolectar la muestra de un niño en pañales, cubra el pañal con el envoltorio plástico. Si dicho envoltorio plástico se coloca en forma adecuada, se puede mantener la materia fecal separada de la orina del niño, garantizando así la obtención de una mejor muestra.

Devuelva la muestra al consultorio médico o al laboratorio de acuerdo con las instrucciones. En el laboratorio, se coloca un pequeño frotis de materia fecal en un portaobjetos de un microscopio y se examina.

Lo que se siente durante el examen:

El examen de laboratorio no involucra al paciente, por lo que no hay ninguna molestia.

Razones por las que se realiza el examen:

El médico puede solicitar este examen si usted tiene signos de una infestación parasitaria, diarrea prolongada de causa desconocida u otros síntomas intestinales.
