PGD Technology
PGD Technology identifies genetic abnormalities in embryos. Chromosomal abnormalities and single gene defects in early embryonic cells are analyzed using sophisticated techniques. These include fluorescence in situ hybridization (FISH) to determine proper structure for all chromosomes and the appropriate number for chromosomes 13, 14, 15, 16, 17, 18, 21, 22, X, Y and DNA analysis to identify single gene defects. Due to the complex technology and expertise involved, there are relatively few PGD Programs in the United States. Fortunately, PGD is an option for anyone in need (if IVF is available) regardless of where you live.
