PGT-A

Pre implantation genetic testing for aneuploidy refers to  a process in which a few cells from the tropho ectoderm of the blastocyst are biopsied and  sent for genetic analysis 

This will identify if the embryo is genetically normal (euploid) or genetically abnormal(aneuploid)

The embryo is formed by the process of IVF or ICSI as usual and allowed to grow till day 5

Then a few cells (about 5-10)are removed by use of laser and sent for genetic analysis

It is the condition where more than one type of cells are present in the same embryo-that is both euploid and aneuploid cells 

Hence there maybe the chance for false positive or false negative results depending on which cells were taken in the biopsy 

It is advised for mainly 

• Older age couples
• Recurrent implantation failures
• Recurrent pregnancy loss
• Testing for specific gene disorders which run in the family-this is called as PGT-M
