Compliance Category

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.
