Preimplantation genetic testing is a bipartite process that allows an embryologist to sift through embryos created via IVF, for genetic defects. The system offers two diverse, revolutionary methods for testing. The first, is preimplantation genetic screening (PGS), a technique that evaluates embryos of chromosomally normal genetic parents for structural or numerical chromosomal errors. The second method is preimplantation genetic diagnosis (PGD), a tool that highlights anomalies in embryos whose parents have a known history of genetic abnormalities. PGD can uncover sex-linked disorders, single gene defects and chromosomal disorders.
Preimplantation genetic testing tools present several advantages for hopeful parents, promoting only healthy embryos that are likely to succeed.
Genetic testing tools like preimplantation genetic screening (PGS) and preimplantation genetic diagnosis (PGD) can provide a keyhole into genetic diseases that may have been inherited by an embryo. This allows embryologists to handpick the best embryos with the lowest risk of acquiring a chromosomal abnormality. This twin-procedure can be a welcome proposition for couples who have a history of inherited conditions.
By selecting embryos that are most likely to thrive in a uterine environment, your embryologist can minimise the risk of a multiple birth. On Cloudnine, our safety norms are tethered to our philosophy of promoting happy, healthy pregnancies. Hence, we limit the number of embryos transferred to two, per in vitro fertilisation cycle.
Preimplantation genetic testing is suited for couples where one or both partners are carriers of sex-linked disorders or genetic or chromosomal abnormalities. The procedure is also effective for women who are over 35 years old, or those who have experienced failed fertility treatments or recurrent miscarriages.
Preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS) are parallel procedures that follow similar steps.
To begin with, a pair of cells is extracted from each multi-cell embryo.
Once several pairs of cells are gathered, each set is examined to gauge the potential presence of an abnormal gene in the corresponding embryo.
Following the selection of the best embryos from the cell evaluation routine, your embryologist will transfer up to two embryos to your uterus for implantation.
There are often embryos left over after embryos are transferred to the uterus. On Cloudnine, we offer advanced cryopreservation facilities that allow you to freeze your surplus embryos for use in future in vitro fertilisation cycles. Cryopreserved embryos can be used for up to ten years.
Genetic testing can prove to be inaccurate if inadequate attention to detail is given. The specialist team on Cloudnine aims to maximise the success rate of genetic screening and diagnosis by carefully engineering every step of the process.
During an in vitro fertilisation cycle, large amounts of ovulation inducing medication could trigger a condition called ovarian hyperstimulation syndrome. The condition can produce several symptoms such as severe abdominal pain, nausea, dark-tinted urine and breathlessness. On Cloudnine, our medication plans are measured and tailored to your needs. We believe in safety, first.
Several global examples of genetic testing have been spotlighted for having produced imprecise results. Smaller clinics that do not possess the expertise to carry out genetic testing run the risk of transferring abnormal embryos to the uterus, owing to false negative results. The Cloudnine gold-standard strives for continual accuracy, offering you the best outcome, always.
