Fluorescence in situ Hybridization (FISH)/Computer Assisted Analysis/Microscopy
Negative: No evidence of numeric chromosomal aberrations associated with pancreatobiliary carcinoma identified.
Positive: Numeric chromosomal aberrations associated with pancreatobiliary carcinoma identified.
Refer to Report.
Laboratory Developed Test (LDT)
Results of this test must be interpreted in conjunction with clinical evidence and other laboratory testing and should not be used alone, as a diagnosis of pancreatobiliary carcinoma.
A positive fluorescence in situ hybridization (FISH) result does not identify location or type of malignancy. FISH abnormalities may be associated with high-grade dysplasia or carcinoma in situ. Cytology and biopsy may help clarify such situations.
