About CNSide™ Cerebrospinal Fluid Assay

The CNSide™ Cerebrospinal Fluid (CSF) assay is a groundbreaking diagnostic tool designed to assess tumor cells that have spread from a primary carcinoma or melanoma to the central nervous system. By analyzing CSF to detect / quantify tumor cells and identify cellular biomarkers using ICC (immunocytochemistry) and FISH (fluorescence in situ hybridization), CNSide™ provides critical information that aids in the effective management of patients with Leptomeningeal Metastases (LM). Our goal is to enhance patient outcomes through precise and actionable insights. *

Step-by-Step Process

The CNSide™ CSF assay employs a meticulous methodology to ensure accurate and reliable results.

1. Sample Collection: CSF is collected via Standard of Care methods (lumbar puncture or Ommaya reservoir) from the patient.
2. Cell Isolation: Tumor cells are isolated and enriched from the CSF.
3. Molecular Analysis: Advanced techniques are used to analyze the molecular characteristics of the tumor cells and circulating tumor DNA. *
4. Data Interpretation: Detailed results are generated and sent to the ordering physician.
