Definición:

La biopsia de tejido gástrico es la extracción de tejido del estómago para su análisis. Un cultivo es un examen de laboratorio en el que se analiza la muestra de tejido en búsqueda de bacterias y otros microorganismos que puedan causar enfermedad.

La muestra para biopsia de tejido gástrico se extrae durante una endoscopia superior.
