TriNetra™-Glio can help individuals where a brain biopsy or surgical resection of the tumor is not possible due to the location of the tumor or other constraints. With proprietary CTC-enrichment and detection technology, a diagnosis of inaccessible tumors will become possible through a risk-free and patient-friendly blood test. The test has previously received CE certification and is already available to patients as 'Trublood™-CNS'.
