Preimplantation Genetic Testing (PGT) has become a powerful tool in modern IVF treatments in the U.S., helping to improve success rates and reduce miscarriage risks. However, there are important facts every patient should understand before opting for PGT. Here are five key truths about PGT screening you need to know.
1. PGT Helps Identify Chromosomal Abnormalities Early
PGT allows clinics to screen embryos for chromosomal abnormalities (PGT-A) or specific genetic diseases (PGT-M) before implantation. This reduces the chance of implanting embryos with genetic defects, improving pregnancy outcomes.
2. PGT Is Not a Guarantee of Pregnancy
While PGT improves the likelihood of a successful pregnancy by selecting genetically healthy embryos, it does not guarantee implantation or live birth. Other factors like uterine health and embryo quality also play crucial roles.
3. PGT Is Especially Recommended for Certain Groups
PGT is highly advised for:
- Women of advanced maternal age (35+)
- Couples with recurrent miscarriage history
- Carriers of genetic disorders
- Those with previous IVF failures
For these groups, PGT can significantly increase success chances and reduce emotional and financial burdens.
4. PGT Adds Additional Costs and Requires Expert Labs
PGT screening involves extra lab work and genetic analysis, increasing overall IVF costs by several thousand dollars. Only certified laboratories with advanced technology can perform accurate and reliable PGT, which is why choosing a reputable fertility center is essential.
5. PGT Does Not Screen for All Genetic Issues
PGT focuses on specific chromosomal abnormalities or known inherited genetic conditions. It does not detect all possible genetic or developmental issues, so genetic counseling and comprehensive testing remain important.
Conclusion
PGT screening is a valuable tool in U.S. IVF that can improve success rates and reduce miscarriage risks, especially for high-risk patients. However, it comes with added costs and is not a 100% guarantee. Understanding these five truths will help you make informed decisions about your IVF journey.
