Prueba de tolerancia a la glucosa oral

Valores normales:

Los valores sanguíneos normales para una prueba de tolerancia a la glucosa oral con 75 gramos utilizada para detectar diabetes tipo 2 son:

  • Ayunas: 60 a 100 mg/dL
  • 1 hora: menos de 200 mg/dL
  • 2 horas: menos de 140 mg/dL. Entre 140 y 200 mg/dL se considera que existe deterioro en la tolerancia a la glucosa (algunas veces llamada "prediabetes"). Este grupo está en mayor riesgo de desarrollar diabetes. Un nivel por encima de 200 mg/dL es un signo de diabetes mellitus.

Los valores sanguíneos normales para una prueba de tolerancia a la glucosa oral con 50 gramos utilizada para detectar diabetes gestacional son:

  • 1 hora: igual a o menos de 140 mg/dL.

Los valores sanguíneos normales para una prueba de tolerancia a la glucosa oral con 100 gramos utilizada para detectar diabetes gestacional son:

  • Ayunas: menos de 95 mg/dL
  • 1 hora: menos de 180 mg/dL
  • 2 horas: menos de 155 mg/dL
  • 3 horas: menos de 140 mg/dL

Nota: mg/dL = miligramos por decilitro.

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.

Los ejemplos anteriores muestran las mediciones comunes para los resultados de estas pruebas. Algunos laboratorios usan diferentes medidas o podrían evaluar diferentes muestras.

Significado de los resultados anormales:

Los valores de glucosa superiores a los niveles normales pueden significar que usted tiene diabetes o diabetes gestacional.

Sin embargo, los niveles altos de glucosa pueden estar relacionados con otro problema clínico (por ejemplo, el síndrome de Cushing).
