SAN JOSÉ, California, 15 de septiembre de 2014 /PRNewswire/ -- Ariosa Diagnostics, Inc. anunció hoy que sus científicos han probado con éxito e implementado un método de cuantificación ADN micromatriz para el Harmony™ Non-Invasive Prenatal Test (NIPT) de Ariosa, que ofrece ventajas destacadas, incluyendo un tiempo de entrega más corto, frente a la anterior aproximación de secuenciación. Los resultados se publicaron de forma online en Fetal Diagnosis and Therapy.

Hasta ahora, todos los NIPTs del mercado que utilizaban cfDNA se habían basado en la secuenciación de ADN, que podría ser un proceso largo y complejo. "Se trata de la primera aplicación de tecnología de micromatriz para un test prenatal no invasivo con ADN sin célula", afirmó Ken Song, consejero delegado de Ariosa. "Las imágenes de micromatriz son una tecnología demostrada y robusta que se ha utilizado en muchas aplicaciones clínicas. La implementación de Ariosa del método micromatriz NIPT demuestra resultados prometedores para mejorar el rendimiento y para desplegar resultados más rápidos en comparación con la secuenciación de ADN".  

Este avance tecnológico en NIPT se debe a la innovación de los científicos de Ariosa como parte de una visión a largo plazo para mejorar el rendimiento y reducir el tiempo de entrega para los pacientes de cara a la recepción de los resultados de este tipo de test. "La aproximación dirigida del test Harmony con la integración de micromatriz ha permitido una mejora superior de calidad con un proceso bastante más corto", comentó Arnold Oliphant, responsable científico de Ariosa. 

El test Harmony es el único capaz de mejorar este método gracias a su objetivo centrado en los cromosomas de interés con el ensayo DANSR™. Cuando se integra con el algoritmo propio FORTE™ de Ariosa, las nuevas micromatrices personalizadas mejoran la cuantificación de la fracción del feto y reducen de forma importante la variedad de la concentración de cromosoma, cuando se le compara con la secuenciación de ADN. Los resultados completos de las pruebas concordantes se consiguieron con una reducción destacada en el tiempo de entrega. Las micromatrices se diseñaron por medio de Ariosa y fueron usados a través de Affymetrix, Inc.

Acerca del test Harmony

El test prenatal Harmony es un test de sangre no invasivo para mujeres embarazadas que se puede usar a las 10 semanas del embarazo. Al evaluar el ADN sin células que hay en la sangre materna, el test puede evaluar el riesgo de trisomía 21 (síndrome de Down) en el feto. Se ha validado con los datos clínicos más grandes establecidos en el espacio prenatal de ADN sin células, haciendo que sea el test de ADN sin células estudiado de forma más amplia. Está disponible en más de 90 países y se ha utilizado para guiar los tratamientos clínicos en más de 300.000 embarazos en todo el mundo.

Acerca de Ariosa Diagnostics

Ariosa Diagnostics, Inc. es una compañía de diagnosis molecular comprometida con la innovación para mejorar el tratamiento a los pacientes por medio del desarrollo y despliegue de pruebas accesibles, de coste contenido e innovadoras. Los test se validan por completo por medio de metodologías rigurosas y completas a fin de asegurar a los practicantes de salud y pacientes que pueden confiar en el rendimiento del test. Ariosa ha desarrollado tecnologías destacadas para realizar un análisis directo del ADN sin células en la sangre. La sede central de la compañía está en San José, California.
