It is a laboratory test in which a labeled complementary DNA or RNA strand made in laboratory is used to localize a specific DNA or RNA sequence in a tissue specimen. DNA and RNA are cellular constituents involved in protein formation and genetic information transmission.
This method is used to identify the characteristics and abnormalities in the DNA that forms part of the chromosomes, even the number of chromosomes. CISH is an alternative to another test called fluorescent in situ hybridization (FISH).
