Fluorescence in situ hybridization (FISH) in prenatal diagnosis

Extract
Currently, the gold standard for prenatal detection of chromosomal abnormalities relies on traditional cytogenetic analysis of banded meta-phase chromosome spreads of cultured cells obtained by amniocentesis, chorionic villous sampling, or fetal blood sampling. Using this technique, a wide range of chromosomal aneu-ploidies and structural aberrations such as translocations, inversions and deletions may be diagnosed with a high degree of accuracy. Unfortunately, this technique has several disadvantages: it is labour intensive, requiring highly trained analysts, and most importantly, it can only be applied to cells undergoing mitosis. Hence the.need for cell culture which may require several days, such that the complete analysis is usually obtained after 7 to 14 days. Thus, there is a need to develop faster methods for prenatal chromosomal analysis.
