Panels that include this biomarker

  • HER-2/ neu FISH, Gastric, Paraffin 483340

    2 analytes · Tumor (formalin-fixed · Fasting not stated · Turnaround 3 - 5 days

    Method and collection
    Method
    Fluorescence in situ hybridization (FISH)
    Collection
    FFPE tissue, preserved in 10% neutral buffered formalin, fixed for 18 to 24 hours. Extended fixation time might increase the incubation time required for pepsin digestion. ASCO/CAP 2013 guidelines recommend fixation time between 6 and 72 hours for breast tissue; however, special ASCO/CAP guidelines have not been established for gastric cancer samples.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
