Test Details
Use
The pan-TRK IHC assay may be used to identify C-terminal protein expression of TRK A, B and C proteins as a surrogate marker of NTRK fusions in solid tumors. Depending on the histologic findings, a positive pan-TRK IHC test may need to be confirmed with an alternative test for NTRK fusions.
