Pre-implantation Genetic Diagnosis. A technique in which embryos are tested for specific genetic disorders before being replaced into the womb.

Pre- Genetic Implantation Diagnosis. The analysis of a cell, under laboratory conditions, from an embryo to check for genetic disease.

A technique for screening embryos prior to implantation for genetic abnormalities. Only embryos free of such abormalities are implanted.

Preimplantation Genetic Diagnosis. Genetic and chromosomal analysis of a cell taken from an embryo before transfer to the uterus.

Preimplantation Genetic Diagnosis. Technique used during In Vitro Fertilization procedures to evaluate the embryos for genetic or chromosomal abnormalities prior to their transfer into the uterus.

Preimplantation Genetic Diagnosis. PGD is a technique used during in-vitro fertilization (IVF) to test embryos for genetic disorders prior to their transfer to the uterus. PGD makes it possible for individuals with serious inherited disorders to decrease the risk of having a child who is affected by the disorder. more info

Preimplantation genetic diagnosis. A procedure performed in conjunction with IVF in which one or two cells are removed from an embryo prior to the initiation of pregnancy and screened for genetic abnormalities.

Preimplantation genetic diagnosis. A method using DNA analysis to determine genetic information on an embryo before replacement.

Preimplantation genetic diagnosis. Method of testing an in vitro embryo for disease relevant genes before transferring it into the uterus: cells are taken from the embryo during the 4 - 8 cell stage, normally three days after insemination (blastomere biopsy). At this point, each single cell still has the capacity to develop into an individual embryo (totipotency). Therefore, cells can be removed without damaging the embryo.

Preimplantation Genetic Diagnosis. The genetic testing of an embryo prior to embryo transfer. One or two cells are removed from an embryo after 3 days of culture in a procedure called embryo biopsy and tested either for a specific genetic disorder (e.g., cystic fibrosis) or for an abnormal number of chromosomes (e.g., trisomy 21 - Down's syndrome). PGD is also performed for gender selection. (details)

preimplantation genetic diagnosis. A process where one cell is biopsied from the embryo for genetic studies before the embryo is replaced.

Pre-Implantation Genetic Diagnosis. Also known as embryo screening, PGD is an advanced procedure used in conjunction with in-vitro fertilization (IVF). The technique helps to prevent an adverse outcome by identifying abnormal embryos while they are developing in our laboratory but before they are transferred to the uterus.

Preimplantation Genetic Diagnosis. A technique that involves examination of the chromosomes contained in the polar body, taken from an egg, or a blastomere from a developing embryo. Using a special technique, scientists and geneticists look for genetic abnormalities that can affect embryo implantation, contribute to miscarriage or cause genetic disease in offspring.

Preimplantation genetic diagnosis. A method of testing IVF embryos for chromosomal or genetic disorders before they are transferred to the uterus; typically one or two blastomeres are removed for genetic testing at about the 8-cell stage of embryonic development.

Pre-implantation genetic diagnosis. an embryo screening technique used to identify embryos with some chromosome abnormalities, such as cystic fibrosis, muscular dystrophy and Huntington's disease. Only the healthy embryos are transferred to the woman's body.

Preimplantation Genetic Diagnosis. Techniques by which embryos fertilised in vitro are tested for specific genetic disorders (e.g. cystic fibrosis) or other characteristics such as sex before transfer to the uterus.

Preimplantation genetic diagnosis (PGD) is a genetic test carried out on embryos created using in vitro fertilisation (IVF), to ensure that only embryos unaffected by a particular genetic condition are returned to the woman's womb.

Preimplantation Genetic Diagnosis. Examination of embryonic cells prior to implantation to determine whether the embryo will be genetically normal.

PREIMPLANTATION GENETIC DIAGNOSIS. Combines  two technically advanced procedures: in vitro fertilization or IVF and genetic analysis of single human embryo cells to identify the genetic disorders which occur naturally in embryos.  PGD is of benefit to couples known to be at risk of passing an inherited disorder to their children and possibly in improving the likelihood of a successful pregnancy and birth following IVF.

Preimplantation genetic diagnosis. A procedure done in conjunction with IVF that allows the selection and transfer of unaffected embryos and avoids the need for terminating an affected pregnancy after diagnosis at later stages of gestation. To analyze for the presence of a genetic defect, it is necessary to remove the first polar body of an unfertilized egg and/or a cell or cells from each embryo. This is called an egg or embryo biopsy and is usually done before insemination occurs, or 3 days after fertilization. Biopsy of one or two cells at the 8-cell stage does not adversely affect preimplantation development.
