RESUMO
In order to determine the impact of the application of the American Thyrold Associations (ATA) criteria for the diagnosis of hypothyroidism in pregnant women in the health district of Vigo, Spain, concentrations of serum thyrotropin (TSH), free thyroxine (T4L) and anti-thyroid antibodies were analyzed, comparing the frequency of pregnant women diagnosed with hypothyroidism and applying the criteria used in the hormone laboratory at Xeral Hospital and referential criteria established by ATA. The application of ATA referential criteria increased by 29.6% the number of female patients diagnosed with hypothyroidism. The application of ATA guidelines had an impact on the measurement of TSH concentrations in pregnant women, which calls for an evaluation of referential values of TSH based on the population and the local diagnostic methods.

Con el objetivo de determinar el impacto de la aplicación de los criterios de la Asociación Americana de Tiroides (ATA) en el diagnóstico de hipotiroidismo en gestantes del área sanitaria de Vigo en España, se analizó la concentración sérica de tirotropina (TSH), tiroxina libre (T4L) y anticuerpos antitiroideos, comparando la frecuencia de gestantes diagnosticadas de hipotiroidismo aplicando los criterios utilizados en el laboratorio de hormonas del Hospital Xeral y los criterios de referencia propuestos por la ATA. La asunción de dichos criterios implicaría un aumento de un 29,6% de pacientes diagnosticadas de hipotiroidismo. La aplicación de los criterios ATA tuvo una repercusión en la medición de la concentración de TSH en gestantes lo que sugiere una evaluación de los valores de referencia de TSH en función de la población y los métodos de diagnóstico locales.
