No Cultivation
One of the biggest advantages of FISH is that cells don't need to be cultivated to perform the analysis, unlike other types of testing that require cultivated cells. As a result, using FISH is a relatively efficient and hassle-free way to perform testing on chromosomes.
Fast Results
Another advantage is the relatively short amount of time it takes to obtain results. Since FISH doesn't require cells to be cultivated, the time it takes to analyze chromosomes is reduced substantially. This is superior to traditional karyotypes, as cell cultivation for karyotypes can take up to two weeks. FISH results can usually be obtained within three or four days of being sent to a laboratory. While this doesn't provide as much in-depth information about chromosomes as a karyotype, it still tells how many chromosomes are present.
Versatility
The process of fluorescent in situ hybridization is also beneficial because of the versatility that it offers. Studying chromosomes by other means usually requires the cells to be dividing, whereas FISH does not. In addition, FISH doesn't require cells to be alive, which most other methods require.
Highly Sensitive
The ability of fluorescent in situ hybridization to detect specific sequences of nucleic acid is also advantageous. In turn, this process is often preferred to older, more traditional methods that are less sensitive.
