Summary
This is a Proprietary Laboratory Analyses (PLA) code, meaning that the code applies to only one unique lab test made by a specific manufacturer or performed by a specific lab. Report 0640U only for CNSide CSF Tumor Cell Enumeration (TCE) from CNSide® Diagnostics LLC. This test analyzes cerebrospinal fluid to detect and count tumor cells in patients with suspected or known leptomeningeal metastases, which means cancer has spread to the membranes and fluid around the brain and spinal cord. The test uses antibody biomarkers to help identify tumor cells and reports whether tumor cells are detected and how many are present.
