How long do PGT-A results take?

Generally one to two weeks from biopsy, though this varies by clinic and by whether testing is done in-house or sent to an external laboratory. Ask your clinic for their expected turnaround. Your embryos are frozen during this time, so there is no pressure on the embryos themselves — the wait does not affect them. What to establish in advance: Who will contact you, and how. Whether you will be told results for all embryos at once. What the report will actually say — how many embryos, and how each is classified. Whether mosaic results are reported at your clinic, and if so what the policy is on transferring them. ESHRE states each centre decides whether to report mosaicism and that its policy should be documented and shared with you during counselling. What happens if no embryo passes testing, including cost implications. That last question is worth asking before you start rather than after. Couples are often unprepared for a result of no transferable embryos, and finding out what that means practically — for cost, for next steps, for whether another cycle is realistic — is easier before it happens than in the moment. If testing is sent externally, ask about transport and whether that adds time. Results should be discussed with you before transfer, and ESHRE specifies they should be provided in writing rather than communicated only by phone.
