PrévueTM PGS (Preimplantation Genetic Screening) is the procedure of evaluating embryos for chromosomal aneuploidy, the presence of either addition or loss of chromosomes in embryos generated from chromosomally normal parents. In conjunction with in vitro fertilization (IVF) treatment, Prevue™ PGS helps to improve the likelihood of a successful pregnancy while reducing the chance of miscarriage or having a child with gross chromosomal disorders.

“Research has shown that transfer an embryo after PGS has higher rate of a successful pregnancy , from 22% to 41%.1

Who should consider PrévueTM PGS

“PGS test is highly beneficial to women above 37 years old. This test helps to improve pregnancy and live birth rate.2
Women of advanced maternal age
Women with recurrent pregnancy loss
Men with infertility issues
Women with repeated implantation failure
Carriers of chromosomal abnormalities
Mothers who had given birth to a child with chromosomal abnormalities

No test is perfect. A PGS test result is specific to the tested sample. The test result only provides supporting evidence for the healthcare provider, and does not draw final diagnostic conclusions. PGS test result is NOT a diagnostic test. If any chromosomal abnormality (aneuploidy/deletion/duplication) is found, the healthcare provider shall be responsible in providing guidance and recommendations based on the currently known abnormalities. While results of this testing is usually highly conclusive, not all chromosomal abnormalities can be detected depending on the chromosomal or embryonic status or other causes.
