Preimplantation Genetic Testing for Structural Rearrangements (PGT-SR)
PGT-SR is a genetic test for detecting inherited chromosomal structural rearrangements in embryos prior to their transfer and enhancing the chance of a successful pregnancy.
This testing is commonly considered after recurrent miscarriages or the birth of an offspring with chromosomal abnormalities, as affected couples are normally healthy and unaware of the chromosomal structural rearrangement that they carry. Their condition simply puts them at an increased risk of creating embryos with the incorrect chromosome number or structure.
