What are the indications for performing a FISH? 

  1. Diagnosis of genetic disorders: FISH is used to detect the presence of chromosomal abnormalities, such as Down syndrome (trisomy 21), Turner syndrome (monosomia X), among others.
  2. Infertility studies: FISH is used to analyze the amount of chromosomes in sperm, which can help determine the causes of infertility.
  3. Tumor studies: FISH is used to detect the presence of certain oncogenes and tumor suppressors in tumor cells, which helps determine the tumor subtype and the best treatment strategy.

It is important to mention that these are just some of the common indications for FISH, and it is recommended that you consult a specialist to determine if this test is appropriate for your particular case.
