Examen de ácido estomacal - Results

Nombres alternativos

Examen de secreción de ácido gástrico

Valores normales:

Normalmente, el volumen del líquido estomacal es de 20 a 100 mL y el pH es ácido (1.5 a 3.5). En algunas situaciones, estos números se convierten a producción ácida real en unidades de miliequivalentes por hora.

Nota: los rangos de los valores normales pueden variar ligeramente entre diferentes laboratorios. Hable con el médico acerca del significado de los resultados específicos de su examen.

Significado de los resultados anormales:

  • La disminución de los niveles del ácido estomacal o de la gastrina puede causar malabsorción.
  • El aumento en los niveles de gastrina puede causar un incremento en la secreción de ácido que puede conducir a la formación de úlceras (síndrome de Zollinger-Ellison).
  • La presencia de bilis en el estómago indica regurgitación del material desde el intestino delgado (duodeno), lo cual puede suceder después de un extirpación quirúrgica de parte del estómago.
