PGT-A: Questions About Embryo Testing and Its Limits
PGT-A tests sampled embryo cells for differences in chromosome number. It is a selection tool, and the decision to use it needs a discussion of benefits, limitations and the embryos available.

Ask which outcome may improve
A claim about miscarriage reduction is not the same as a claim about a higher overall chance of having a baby. HFEA cautions that PGT-A is not proven to improve live-birth prospects for most fertility patients and can reduce the number of embryos available for transfer.
Testing a sample also has interpretive limits. Results described as mosaic or inconclusive can create additional decisions rather than a simple yes-or-no answer.
Discuss the plan before the biopsy
Ask why testing is recommended for your situation, what the laboratory reports and how uncertain results are handled. Clarify whether genetic counselling is appropriate.
Find out what happens if there is only one embryo, no embryo is recommended for transfer or the result is inconclusive. These questions are easier to consider before treatment than after an unexpected report.
Keep the comparison complete
Request an explanation of biopsy, freezing, testing and transfer costs, including possible repeat testing. Ask whether the proposed benefit is based on evidence from people similar to you.
Do not treat “tested” as meaning free of every genetic or health condition. Ask what the test can and cannot detect and what pregnancy screening may still be advised. A decision should reflect your priorities and the current evidence, without presenting an optional test as a universal requirement.
