This package is an extended version of the “Envision” package but includes the DNA test for the DiGeorge syndrome as well. Like the “Envision” package, the “Envision Plus” package includes one ultrasound scan and blood sampling for the Harmony Non-invasive Prenatal DNA Test.
The ultrasound scan is a 10-15 minute 2D scan session and you will get a black and white photo. At this stage, we can confirm the presence of one or more embryos and gestational sacs and assess the gestational age. This can also be known as a “dating scan”. We can confirm the presence of a heartbeat and check the size of the embryo and ensure the baby is the right size for gestational age. We can also ensure the embryo has implanted within the uterus and there is not an ectopic pregnancy occurring.
The Harmony test, included in this package, is a non-invasive test that delivers straightforward answers on the risk of trisomy 21 (Down syndrome), 18 (Edwards syndrome), and 13 (Patau syndrome) as well as the microdeletion – the lack of a tiny part – of chromosome 22 (DiGeorge syndrome) using a single blood draw. In addition, you have the option to evaluate X and Y sex chromosomes. A maternal blood sample is taken and the fetal DNA content of the sample is analyzed by molecular biology techniques. Test results are reported back – usually – in 7 business days.
