WebTechniques such as FISH, CGH, and PCR have high rates of sensitivity and specificity. These procedures provide results more quickly than traditional karyotyping because no cell culture is required. FISH can detect genetic deletions involving one to five genes. It is also useful in detecting moderate-sized deletions, such as those causing Prader-Willi … WebFor a positive control, use test DNA (Cat.
