Your journey to parenthood starts here
Preimplantation Genetic Testing (PGT) is a laboratory technique used during IVF to screen embryos for genetic or chromosomal conditions before transfer. A small sample is taken from the embryo and tested, helping in the selection of embryos for implantation.
PGT helps identify embryos with normal chromosomal patterns and detect specific genetic concerns. It is used in selected cases based on medical history and treatment planning.
Provides specialized genetic testing methods to screen embryos for chromosomal abnormalities and specific inherited disorders before transfer.
PGT-A - Screening for chromosomal number changes
PGT-M - Testing for specific genetic disorders
PGT-SR - Testing for structural chromosomal rearrangements
PGT may be considered in specific situations.
PGT helps in better understanding embryo health before transfer.
Helps identify embryos for transfer based on testing.
Screens for certain genetic or chromosomal conditions.
Provides information for decision-making during IVF.
A stepwise process involving embryo creation, biopsy sampling, genetic analysis, and selection for transfer based on test results.
