Information for Patients

Genesis Serenity is a highly accurate, non-invasive prenatal test (NIPT) that screens for the most common chromosomal abnormalities. It offers the reassurance of knowing in the early stages of pregnancy (as early as 10 weeks) if birth conditions such as Down syndrome, Edward’s syndrome and Patau syndrome are present.

Non-invasive prenatal tests (NIPT) are an advanced screening option which is safe and poses no risk to mother or baby. A healthcare professional will discuss the options with you to make an informed choice. Serenity NIPT involves a simple blood test from you, as the expectant mother. Also you will be required to have an ultrasound scan prior or usually at the same time as the blood test to date and check the viability of your pregnancy. Once you have seen your healthcare professional and had your scan, a single maternal blood sample is taken and sent to a Genesis Genetics lab for processing.

The technology advances are such that circulating cell free foetal DNA is able to be accurately analysed from the maternal blood. The test is so sensitive it can pick up readings of small DNA fragments that break away from the placenta and mix with the maternal blood. Amazingly these cells do not stay around in the maternal blood for longer than a few hours post birth.

Although any biologically related test is never 100%, the clinical evidence gathered over recent years firmly backs up the extremely high accuracy rates quoted in the test performance data sheets. After NIPT, the requirement for further testing (ie CVS or Amniocentesis) is dramatically reduced.
