Embryos may be tested for chromosomal abnormalities using a specialized diagnostic approach called Preimplantation Genetic Testing for Aneuploidy (pgt-a testing), formerly known as PGS. Compared to other antenatal screening tests, this one may be administered as early as 11–14 weeks into the pregnancy.
The Preimplantation Genetic Test for the identification of Aneuploidy, or PGT-A, is a method that enables preimplantation genetic analysis of the embryo. It enables the detection of chromosomal abnormalities to prevent embryo transfers that will not result in a healthy baby.
An embryo biopsy, which involves removing a limited number of cells from an embryo, is performed during the fifth and sixth days of embryonic development. The embryo that was biopsied is vitrified the same day, right up until the results of the PGT-A test come in.
The laboratory needs around 10 days to get the findings, but the shorter the wait, the better the treatment’s chances of effectiveness.
Can PGT-A identify any diseases?
Diseases associated with abnormalities in the normal chromosomal number may be detected with PGT-A testing. This test may detect Down syndrome, Edwards syndrome, Patau syndrome, Klinefelter syndrome, Turner syndrome, and many more.
Is a PGT-A or similar genetic test necessary in some situations?
The patient must be having in vitro fertilisation therapy for this test to be performed.
A large proportion of patients over the age of 40 choose PGT-A for treatments using their eggs. The need for an A-PGT becomes clear when the proportion of aneuploidies grows exponentially with age.
Due to the potential for a gamete abnormality to create embryo difficulties, this method is also advised for situations where there have been repeated miscarriages or recurrent implantation failures following IVF.
In terms of genetic testing reliability, PGT-A is unrivalled. It is the optimal option to guarantee a healthy delivery devoid of hereditary disorders.

How many people passed the test:
According to recent reports from clinic-supplying labs, the clinical pregnancy rate with euploid embryo transfer may reach 65% each cycle.
The odds of success are the same across all age groups, in contrast to embryos that have not been identified. More trials are required to confirm that PGT-A is effective and may be used routinely.
However, recent research shows it can increase clinical pregnancy rates and reduce miscarriage rates.
