What is the Genesis Serenity prenatal test?

This test looks at the chromosomes present in a mother and fetus during pregnancy, to determine the likelihood of conditions such as Down Syndrome, Edward’s Syndrome and Patau Syndrome.

How does it work?

The Genesis Serenity prenatal test uses verifi® test technology developed by Illumina, the world largest DNA sequencing company. The test measures genetic material (or DNA) from a pregnant woman’s blood to look for too few or too many copies of chromosomes in the mother and fetus. Missing or extra copies of chromosomes are referred to as “aneuploidies” and may be related to conditions in pregnancy where an extra chromosome is present such as trisomy 21 (Down syndrome), trisomy 18 (Edward’s syndrome), or trisomy 13 (Patau syndrome).

The test can also look for other conditions caused by missing and extra copies of other types of chromosomes, called sex chromosomes (X and Y). Sex chromosome aneuploidies are conditions in which there is a change from the usual 2 copies of sex chromosomes in males (XY) or females (XX). All of these conditions may cause mental or physical defects, with different levels of severity. This test is available for singleton and twin pregnancies.

How is the Genesis Serenity prenatal test performed?

A sample of your blood is drawn and the genetic material is tested. The Verifi test uses DNA sequencing to count the number of copies of all chromosomes, and then uses a calculation method to determine if there are too many or too few copies of chromosomes 13,18, 21, X, Y present in your fetus.
