Liquid biopsies are not as sensitive as IHC or FISH for testing NTRK gene fusions . If circulating DNA and RNA volume is low (e.g. when the tumour volume is low), a test failure or false negative may result. Finally, it is currently not available for routine clinical use as further development is required .
