Genetic Testing – PGD & PGS

Some of the important diseases are caused by chromosomal abrnomalities, for example down’s syndrome. These are called as genetic diseases. Also, some of the causes of infertility (recurrent abortion etc) could be due to genetic abnormalities.

Therefore, testing the embryo for genetic abnormalities is a very important step for successful outcome of the treatment. Also, this is very important to have a healthy baby. Some couples would like to opt for gender selection which can be done through these tests.

There are 2 types of genetic tests which can be performed:-
1) Pre-implantation genetic diagnosis (PGD):- This is a diagnosis test where tests are performed for known genetic conditions. The wife or husband or both may have any of such genetic conditions or have a family history or their previous child would be having such conditions.
2) Pre-implantation genetic screening (PGS):- This is a broad screening test to identify various common types of genetic abnormalities.

How it is performed?

In both PGS and PGD, one or more cells from the embryo are taken out by a biopsy procedure on the 3rd or 5th day and send to a advanced genetic laboratory.
The laboratory would perform the respective genetic tests and give the report.
Doctors and the embryologist at the clinic would review the report, counsel the patient and take further decisions.
