What is Spectrum®?
Spectrum preimplantation genetic screening (PGS) evaluates embryos for extra or missing chromosomes. PGS is an option for any in vitro fertilization (IVF) patient. Spectrum preimplantation genetic diagnosis (PGD) tests embryos for specific inherited genetic disorders.
Spectrum PGS what does it screen for article
Testing for many possibilities
24-chromosome preimplantation genetic screening (PGS) evaluates the number of chromosomes in embryos created using IVF. Embryos with the normal number of chromosomes have a better chance of implanting and developing into a healthy pregnancy.
Single-gene preimplantation genetic diagnosis (PGD) testing can be performed as part of an IVF cycle. Available for couples identified as at-risk of having a child with a specific genetic disorder, PGD predicts which embryos are affected or unaffected with specific genetic disorders. Couples can then use this information to select which embryos are transferred. Spectrum's single-gene PGD testing is performed concurrently with 24-chromosome PGS on a single embryo sample.
Translocation and Inversion testing
Translocation and inversion PGD testing can be performed as part of an IVF cycle. A person who carries a balanced chromosomal rearrangement may have an increased risk of passing on too little or too much genetic information to the embryo, possibly causing miscarriage, birth defects, or learning disabilities. Embryos can be tested for extra or missing chromosome pieces. Embryos with normal or balanced chromosome results are selected for transfer to the mother’s uterus.
