Sequencing A key breakthrough in modern laboratory medicine, preimplantation genetic diagnosis PGD detects genetic abnormalities that cause birth defects or fatal illnesses, allowing embryos to be chosen before being implanted into a uterus, thereby avoiding selective pregnancy terminations. While this technology provides a lot of answers, its increasing sophistication is raising new questions about how to resolve the ethical controversies it creates. A special January issue of Clinical Chemistry focusing on women's health explores some of these ethical issues, highlighting how the rapid pace of scientific discovery can sometimes outpace society's old categories for ethics in healthcare Clin Chem ; doi: Next generation sequencing and other advancements are enabling labs to use PGD in new ways beyond the scope of simply improving chances for a successful pregnancy and avoiding disease.
Over the next three to five days, the embryos will divide into multiple cells. After this cell collection, the embryos are safely frozen. This process takes at least one full week.
Any additional embryos that are free of genetic problems are kept frozen for possible later use while embryos with the problematic gene s are destroyed. This testing process may take weeks.
Getting from the egg retrieval process to the final results of PGD can take several weeks. If you think about it, this process includes collection, fertilization, days of development, weeks of testing, and scheduling an appointment to discuss results with your doctor.
Who can benefit from PGD? What are the benefits of PGD? The following are considered benefits of PGD: PGD can test for more than different genetic conditions. What are the concerns of PGD? Keep in mind that preimplantation genetic diagnosis does not replace the recommendation for prenatal testing.
If you are interested in PGD, talk with your doctor, genetic counseloror a fertility specialist to discuss your options.

Amniocentesis is usually done when a woman is between 14 and 16 weeks initiativeblog.comlantation genetic diagnosis: done in conjunction with IVF.
In vitro fertilization mature eggs are collected from the ovaries and fertilized by sperm in a lab. Preimplantation genetic diagnosis (PGD) involves testing for specific genetic conditions prior to the implantation of an embryo in the uterine wall. This form of genetic screening has been made possible by the growth of in-vitro fertilization (IVF) technology, which allows for the early stages of development to occur in a laboratory dish rather than in .
Nov 24, · Preimplantation genetic diagnosis (PGD) involves genetic analysis of artificially fertilised embryos to select an embryo with a desired genotype before it is implanted. 1,2 Since the s, over cycles of PGD have been performed worldwide.
3 The technique has been used to test for disorders caused by a single gene (cystic fibrosis. The Controversy of Preimplantation Genetic Diagnosis and Its Effect on Social Morality.

The future growth of preimplantation genetic diagnosis (PGD) will depend on refinements in genetic knowledge and genetic analysis of blastomeres.
Equally important, however, is an acceptance of the ethical legitimacy of parents using technologies to select genetic traits of offspring.
