PGT result timing: laboratory stages and transfer planning

How to use this guide

This page provides the explanation. For a separate practical record, use Waiting for PGT results: a laboratory status tracker. Record the responsible provider’s answers rather than treating a generic example as confirmation for your case.

Understanding PGT and Its Timeline

The PGT result timetable depends on the ordered test, sample receipt, laboratory workflow and clinical review. Request the laboratory’s current estimate and the event from which that estimate is measured.

Factors That Influence PGT Result Timing

Type of PGT Test

Different PGT tests require different processing times. PGT-A (aneuploidy screening) typically takes less time than PGT-M (monogenic disorders) or PGT-SR (structural rearrangements), which may involve more complex analysis. Confirm with your clinic which test you need and its estimated turnaround.

Lab Schedule and Workflow

Thai labs may have specific batch processing days. For example, biopsies may be collected on certain days of the week, and results may be released on fixed schedules. Ask your clinic about the lab’s weekly routine and how it aligns with your cycle.

Number of Embryos Tested

Testing multiple embryos can sometimes extend the timeline, though many labs process batches simultaneously. Your clinic can give you a more personalized estimate based on your expected number of embryos.

Shipping and Logistics (if applicable)

If your clinic sends biopsies to an external lab, additional shipping time may be needed. Confirm whether the lab is on-site or off-site, and factor in any courier delays.

Impact on Fresh vs. Frozen Transfer Decision

One of the most important planning decisions is whether to attempt a fresh embryo transfer or freeze all embryos for a later frozen embryo transfer (FET). PGT results directly influence this choice.

Fresh Transfer

Ask the treating team how sample collection, test completion and result interpretation affect the proposed transfer pathway. This page cannot confirm that results will be available for a particular transfer or that one pathway is mandatory.

Frozen Transfer (FET)

With a frozen transfer, embryos are biopsied and vitrified (frozen) while awaiting results. Once results are received, only euploid (normal) embryos are selected for transfer in a later cycle. This approach allows for PGT but requires additional time—typically one to two months between retrieval and transfer, depending on your clinic’s schedule and your personal timeline.

Planning Your Cycle Timeline as an International Patient

If you are traveling to Thailand for IVF with PGT, careful planning is essential. Here are key steps and questions to discuss with your clinic:

• Initial consultation: Discuss your medical history, PGT options, and estimated timelines.
• Cycle start: Plan your travel dates around your menstrual cycle and medication schedule.
• Egg retrieval and biopsy: Coordinate your stay to cover the retrieval and any required follow-up.
• Waiting period for results: You may return home while waiting for PGT results, but confirm how results will be communicated (email, portal, phone).
• Frozen transfer preparation: If FET is needed, plan a second trip or discuss remote monitoring options with your clinic.

Questions to Confirm with Your Clinic

Because timelines can vary, always verify the following directly with your treating clinic:

• What is the estimated turnaround time for my specific PGT test?
• Does the lab process biopsies daily or on specific days?
• What is the current expected report date, what could change it, and who will provide a status update?
• How will I receive the results, and who will explain them?
• What is the recommended interval between retrieval and FET?
• Are there any additional costs for expedited processing?

Summary

Use the laboratory’s case-specific estimate and separate report release from the date on which a clinician can review the result. Confirm storage, follow-up and travel dependencies in writing.
