Result Turnaround Time
1 - 2 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
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.
Special Instructions
