Previda®
Preimplantation Genetic Testing
for Aneuploidies (PGT-A)
What is Previda®?
Previda® is a preimplantation genetic test for aneuploidies (PGT-A). Previously known as preimplantation genetic screening or PGS, PGT-A is a test for couples using in vitro fertilization (IVF). It is designed to evaluate the genetic health of the embryo prior to implantation. By checking for missing or extra chromosomes (aneuploidies), the test helps your IVF team select the best embryo for transfer and improves your chances of achieving a successful pregnancy.
Why Use Preimplantation Genetic Testing for Aneuploidies?
Screening for chromosomal abnormalities (aneuploidy) before implantation offers many benefits:
Increase chance of implantation
Decrease risk of miscarriage
Reduce time and costs of having a healthy baby by reducing number of IVF cycles needed
IVF can be a stressful and overwhelming process for many families. PGT-A with Previda® provides peace of mind. You can relax knowing that your doctors have information allowing them to confidently select chromosomally healthy embryos and improve your chances of achieving a successful pregnancy.
Next Generation Sequencing for Accurate, Reliable Results
With Previda®, embryos are screened for chromosome copy number using next generation sequencing (NGS). NGS provides higher accuracy and sensitivity compared to conventional methods such as microarray or fluorescent in situ hybridization (FISH). Our simplified workflow makes it easy to get tested as a part of your ongoing IVF process.
