At Arlington House Medical Centre we are now offering a new DNA based blood test known as 'Harmony Prenatal Test'. It is a simple blood test that can check the risk to your pregnancy of having genetic conditions including Down's syndrome (trisomy 21), Trisomy 18 (Edward's syndrome) and Trisomy 13 (Patau syndrome). Harmony testing is more accurate than traditional tests and can be done as early as 10 weeks or later in pregnancy. Results are usually available within a week. Call us to schedule an appointment or discuss further.
