What does it mean?
Preimplantation genetic testing for aneuploidy screens chromosome number in a small sample of cells from an IVF embryo. The result can inform a conversation about embryo transfer.
PGT-A is an option to discuss, rather than a required step for everyone. Consider the possible benefit alongside uncertainty, cost and the number of available embryos.
See how it connects.
Genetic question
Start with the question the test is designed to address.
Test information
A result describes what was measured, within the limits of that test.
Clinical context
Counseling connects the result to your options and the uncertainty that remains.
Simplified educational illustration. Select each concept at your pace; not a clinical image, fixed timetable or prediction.
The sequence, at a glance.
Discuss suitability
Review the purpose, alternatives and consent.
Sample selected cells
A trained embryologist biopsies an eligible embryo.
Analyze & report
A genetics laboratory analyzes the sample.
Review the result
Discuss findings and individualized transfer planning.

Counseling and test planning. - After embryo development
Biopsy and freezing may be coordinated. - After the report
Interpretation and transfer planning; timing varies.
Your question checklist
Checks are temporary. No information is saved or submitted.
Know the limits.
Routine PGT-A for all IVF patients has not been shown to improve overall outcomes. Biopsy samples only some cells, and results may be mosaic, uncertain or unavailable. PGT-A cannot guarantee an ongoing pregnancy or a healthy child; prenatal screening or diagnosis may still be discussed.
How can I prepare for a consultation?
Write down the questions that matter to you. Ask the team how to share prior records securely and whether counseling or financial follow-up would help.

From clinical question,
to careful decision.
Information matters most when it becomes a clear conversation.
Your history, test results and laboratory findings help guide an individualized plan. Your care team can explain what is known, what remains uncertain and what comes next.
- Start with your question
Your goals and concerns shape the discussion. - Gather relevant information
Ask which assessments may help and why. - Connect the findings
Review the picture together, not a number alone. - Decide and reassess
Revisit the plan as new information emerges.
The science is connected.
