PGT-SR- Preimplantation Genetic Testing for Chromosomal Structural Rearrangement

Prevent the transfer of embryos with abnormal chromosome structure.

You are indicated for PGT-SR if you or your partner is a carrier of

  • Reciprocal Translocation
  • Robertsonian Translocation
  • Inversion
  • Insertion

We introduced third-generation long-read sequencing in distinguishing normal from balanced carrier embryos in 2018, allowing the couple to selective transfer of euploid non-carrier embryo [1]. This helps to prevent the vertical transmission of chromosomal structural rearrangement to next generation.

UniPGT-plus also identifies euploid non-carrier embryo when reference is available.
