Cytogenetic vs molecular testing

WebFISH is a molecular method that is a cytogenetic tool that is used to detect chromosomal abnormalities such as translocations, deletions, inversion, and duplications.3. The method involves using a fluorescently labelled DNA or RNA probe that is complementary to a specific target sequence. After denaturing double stranded DNA to single stranded ... WebPrenatal diagnosis of chromosomal abnormalities in fetuses, and investigation of genetic causes for pregnancy loss can be tested through a number of cytogenetic techniques. This includes conventional chromosome studies (karyotyping), chromosomal microarray (molecular karyotyping), and fluorescence in situ hybridisation.
