When patients present with neurologic symptoms suggestive of leptomeningeal disease (LMD), timely and accurate molecular insight can be critical. Traditional diagnostics—CSF cytology, imaging, and plasma-based testing—often lack sensitivity in this setting.
Liquid Trace® on CSF is designed to address these gaps:
· Higher tumor signal than plasma for CNS-confined disease due to the blood–brain barrier
· Improved detection when cytology is negative or equivocal
· Comprehensive genomic profiling from limited CSF input, supporting therapy selection
· Actionable insights for metastatic and primary CNS malignancies using a single assay
· Clinically practical when tissue is unavailable or unsafe to obtain
