Comparative Genomic Hybridization (CGH)
CGH is a diagnostic test for melanoma, using DNA copy number changes. CGH has the potential to reveal whether a melanocytic lesion removed from a patient was benign or malignant.
Fluorescent In Situ Hybridization (FISH)
FISH is a diagnostic test that detects the differences in chromosomal alterations between melanoma and nevi. FISH may provide useful diagnostic information in cases that cannot be classified reliably by current methods.
