Preimplantation Genetic Testing for Multiple Genetic Conditions (PGT-A or Multigene Analysis)

Published: August 9, 2026Updated: August 16, 2026

This test analyzes genetic material from embryos created through in vitro fertilization (IVF) to identify or exclude certain inherited conditions before transferring them to your uterus.

What This Test Measures

This test evaluates embryos for a broad range of genetic variations that could cause inherited disorders, such as chromosomal abnormalities (e.g., Down syndrome) or specific single-gene conditions (e.g., cystic fibrosis, sickle cell disease). It typically includes testing for common conditions but may also assess carrier status for other inherited traits.

How the Test Works

During IVF, embryos are created in a lab and then biopsied (a small sample of cells is taken) before being tested. Genetic material from these cells is analyzed to identify any genetic abnormalities or risks. Results are used to select the healthiest embryos for transfer to your uterus.

Preparation and Process

No special preparation is needed before embryo testing. The process begins during the IVF cycle, where embryos are grown in the lab and tested for genetic compatibility. Results are usually available within a few weeks, allowing you to choose the best embryo(s) for transfer.

When This Test Is Recommended

This test is often recommended for individuals or couples who have a history of genetic disorders, infertility issues, advanced maternal age, or those who wish to avoid passing on certain inherited conditions to their children.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Will this test affect my IVF success rate?
Yes, PGT can improve IVF outcomes by selecting embryos that are more likely to thrive, potentially increasing the chance of a successful pregnancy and live birth.
How long does it take to get results?
Results typically take about 1–2 weeks after the genetic testing is completed, depending on the laboratory’s processing time.
Can I choose which embryo(s) to transfer based on these results?
Yes, genetic testing allows you to select the healthiest embryos for transfer, helping to optimize your chances of a successful pregnancy.
