Examen de la hormona estimulante de la tiroides (TSH) - Results

Nombres alternativos

Hormona estimulante de la tiroides; Tirotropina

Valores normales:

Los valores normales son de 0.4 a 4.0 ml U/L (miliunidades internacionales por litro).

Sin embargo, aquellas personas sin signos ni síntomas de una actividad tiroidea baja que tengan un valor para hormona estimulante de la tiroides por encima de 2.0 m lU/L, pero niveles normales de T4, pueden desarrollar hipotiroidismo en algún momento en el futuro. Esto se denomina hipotiroidismo subclínico (tiroides levemente hipoactiva) o hipotiroidismo en etapa temprana. Cualquier persona con un valor para hormona estimulante de la tiroides por encima de este nivel debe estar bajo estricta observación médica.

Si usted está bajo tratamiento para un trastorno tiroideo, el nivel de la hormona estimulante de la tiroides debe estar entre 0.5 y 3.0 ml U/L.

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 niveles por encima de lo normal pueden indicar:

  • Hipotiroidismo congénito (cretinismo)
  • Exposición a ratones (trabajadores de laboratorios o veterinarios)
  • Hipotiroidismo primario
  • Resistencia a la hormona tiroidea
  • Hipotiroidismo dependiente de la hormona estimulante de la tiroides

Los niveles por debajo de lo normal pueden deberse a:

  • Hipertiroidismo
  • Deficiencia de hormona estimulante de la tiroides
  • Uso de algunos medicamentos, incluyendo agonistas de la dopamina, glucocorticoides, análogos de somatostatina y bexaroteno
