How Long Does PGT Testing Take?

IVF genetic testing of embryos has been advocated for use in conjunction with In Vitro Fertilization in efforts to identify and transfer only genetically normal embryos and thereby possibly improve the likelihood of a successful pregnancy.

How long does PGT testing take? Even though Preimplantation Genetic Testing is a complex procedure, it can be completed within a short period of time. It usually takes one to two weeks for the result to become available.

The PGT procedure consists of the following steps:

  1. In Vitro Fertilization to create embryos
  2. Extended embryo culture to blastocyst
  3. Blastocyst trophectoderm (embryonic tissue) biopsy

    An embryo biopsy is performed by creating an opening in the eggshell around the embryo. It is possible to safely remove six to eight cells through this opening using a special microscope with micromanipulators. The cells are taken from the trophectoderm only (future placenta cells, genetically identical to embryonic cells). The “inner mass” cells (embryonic cells) are not removed.


    Blastocyst PGT


    Since it takes one to two weeks to carry out the embryo genetic analysis, the blastocysts are cryopreserved immediately after their biopsy and stored in liquid nitrogen in our IVF laboratory.

  4. Genetic analysis of the embryonic tissue
  5. Liquid nitrogen storage of the cryopreserved embryos
  6. Subsequent Frozen Embryo Transfer
