Preimplantation Genetic Testing
Knowing even before you are pregnant
From comprehensive fertility-related diagnostics to advanced fertility services, we have the solutions for you no matter what your fertility goals are.
Types of PGT for your future baby
Looking into all 23 pairs of chromosomes of your embryos, PGT-A determines if there is any occurrence of abnormal chromosome numbers, meaning if there are any extra (trisomy, such as Down’s syndrome) or missing chromosomes (monosomy) within your embryos. An embryo that carries abnormal chromosome numbers is aneuploid, while ones with normal chromosome results are euploids.
The 23 pairs of chromosomes tested in PGT-A includes the chromosome pair X and Y because it also screens for sex-linked genetic disorders. Inadvertently, in the process, this test reveals the gender of each embryo with female embryos carrying two X chromosomes and male embryos one chromosome each of X and Y.
PGT-M is done for a large number of single gene disorders including Huntingtons' disease, Cystic fibrosis, Thalassaemia, Duchenne muscular dystrophy, Fragile-X and BRCA1/BRCA2 (hereditary breast/ovarian cancer). PGT-M involves testing embryos created through in-vitro fertilization (IVF) and then transferring unaffected embryos.
How PGT takes place within your IVF treatment
After the stimulation stage, eggs are collected from you or your egg donor.
When your embryos progress into blastocysts (5 or 6 days old), a tiny clump of cells are extracted from each embryo before the embryos are cryopreserved.
With your sperm or donor’s sperm, the eggs are fertilized in the embryology lab to form embryos.
The biopsied cells are sent for genetic testing that takes about 2 – 3 weeks for results to come back.
With the PGT results, only the embryos free of a known genetic disorder, or the healthy ones with the best chance of implantation based on chromosome numbers and structures will be considered for transfer into your womb or that of your chosen surrogate’s.
