From the Research
The time frame to get embryo testing results back typically ranges from 7 to 14 days after the embryo biopsy is performed. This testing, known as Preimplantation Genetic Testing (PGT), analyzes embryos for chromosomal abnormalities or specific genetic conditions before implantation during IVF, as discussed in 1. The exact turnaround time depends on several factors including the specific laboratory performing the analysis, the type of testing being conducted (PGT-A for aneuploidy screening, PGT-M for monogenic disorders, or PGT-SR for structural rearrangements), and the complexity of the genetic analysis required.
Key Factors Influencing Turnaround Time
- The specific laboratory performing the analysis
- The type of testing being conducted
- The complexity of the genetic analysis required During this waiting period, the tested embryos remain cryopreserved (frozen) to maintain their viability until the results are available and a transfer can be scheduled. The testing process involves complex genetic analysis techniques such as next-generation sequencing or PCR, which require meticulous laboratory work to ensure accurate results, explaining why the process takes several days to complete, as noted in 2 and 3.
Recent Studies and Their Findings
- A 2025 study published in Fertility and Sterility 1 found that PGT-A is associated with a shorter time to pregnancy resulting in a live birth for patients who are at least 38 years old.
- Another study from 2024 in Reproductive Sciences 3 discussed the evolution of PGT-A and its current applications and limitations.
- A review in Archives of Gynecology and Obstetrics from 2024 2 summarized the development and applications of PGT, including its pros and cons. Given the most recent and highest quality evidence from 1, the recommended time frame for embryo testing results is between 7 to 14 days, prioritizing the reduction of morbidity, mortality, and improvement of quality of life for patients undergoing IVF.
