FISH. Chromosome 3 and p16 (rhodamine), chromosome 7 and 17 (FITC). (A and B) Example of the same urine specimen cell, in which the percentage of FISH signals are greater than the cut-off value (CSP3, 23%; CSP7, 21%; GLPp16, 7%; CSP17, 9%). (C and D) Example of the same urine specimen cell, in which the percentage of FISH signals are lower than the cut-off value (CSP3, 3%; CSP7, 2%; GLPp16, 4%; CSP17, 2%).
Note: Magnification ×1000 (A–D).
Abbreviation: FISH, fluoresceuce in situ hybridization.
