FAQ - PGT Testing

Preimplantation Genetic Testing (PGT) is an embryonic procedure done in unison with IVF where a tissue biopsy of a developing embryo is taken and tested for genetic (ab)normalities. The tissue biopsy takes place on blastocysts stage embryos. After which, the tissue is sent to a third-party genetics lab for analysis.

PGT is broken into 3 main testing categories: Preimplantation genetic testing for aneuploidies (PGT-A), monogenic/single gene defects (PGT-M), and chromosomal structural rearrangements (PGT-SR)

Formerly known as PGS (preimplantation genetic screening), PGT-A gives information about the number of chromosomes within IVF embryos. Those with normal results have higher odds of achieving a successful pregnancy. It is also often used to choose the sex of the anticipated child.

PGT-M is performed on blastocyst stage embryos to significantly reduce the risk of having a child with a specific genetic disease. Whether you have a genetic disorder or have learned of a risk status through screening, an affected family member, a pregnancy, or a child with a known single-gene disorder, PGTM may be the solution foryour family-building needs.

PGT-SR is for people who have a chromosome rearrangement and should thus be considered in conjunction with IVF if you had a child or pregnancy with a chromosome rearrangement or if you or your partner is a carrier of translocations.

Any PGT cycle eliminates the ability to do a fresh embryo transfer. For PGT-M and PGT-SR, we need approval from CooperGenomics, our testing company, prior to starting your IVF cycle. Results can take 2-4 weeks depending on the type of PGT you plan to do. Cost will also vary with CooperGenomics.

We cannot guarantee normal embryos or a specific gender.

Statistically, 50% of all fertilized embryos grow to the blastocyst phase, which is when your embryos would then be biopsied. Starting with 6 eggs may ultimately result in only 2 to 3 embryos to biopsy, so we suggest that you consider purchasing additional eggs to maximize your outcome.  

Additional eggs are $1,500/egg. Keep in mind that this test is not perfect, and there is a degree of error with those results.

Should you request this testing, you should expect a bill for an additional $2,000 to $3,000, depending on the number of embryos tested.

Yes. Results usually take between 10 to 14 days once Cooper Genomics receives the samples. You may not start medications for your transfer cycle until results are received.
