Nombres alternativos

Examen iontoforético del sudor; Cloruro en el sudor; Prueba del sudor

Valores normales:

El resultado de una prueba de cloruro en sudor menor o igual a 39 mEq/L en un bebé de más de 6 meses probablemente signifique que no hay presencia de fibrosis quística.
Un resultado entre 40-59 mEq/L no brinda un diagnóstico claro y se necesitan exámenes adicionales.
Si el resultado es de 60 mEq/L o mayor, la fibrosis quística está presente.

Nota: mEq/L = miliequivalentes por litro.

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.

Algunas afecciones, como deshidratación o hinchazón (edema), pueden afectar los resultados del examen.

Significado de los resultados anormales:

Un examen anormal puede significar que el niño tiene fibrosis quística.
