On Cancer Heterogeneity


QCDx is a medical company dedicated to providing solutions for detecting and profiling rare cells in the blood circulation

Our mission is to reveal circulating cancer cell heterogeneity both In early stage and advanced disease to deliver precision cancer diagnosis  that will enable the oncologist to optimize treatment, monitor therapy, characterize metastasis and assess treatment toxicity

Ultimately, to improve patient outcomes and their quality of life


Treatment Optimization



The RareScope™ system addresses the unmet need for enrichment-free profiling and isolation of rare Circulating Tumor Cells (CTCs) by 3-D optical tomography of all nucleated cells from a blood sample

When a biopsy is not an option, CTC can offer real-time cancer intelligence with a frequent, minimally invasive blood test

The novel MultiFluor™ multiplex immunofluorescent probes will enable rapid CTC profiling with 12+ biomarkers in intact & live cells at the time of detection. Different fluorescent antibody probe combinations can be utilized for personalized and real-time intelligence on treatment-specific markers also in all cytology and cytopathology applications

Our combined RareScope™ & MultiFluor™ platform has multiple applications In cancer diagnostics, cancer research and the pharmaceutical industry in all stages of drug discovery and clinical trials 

RareScope™ for Rare Cell Profiling

The RareScope analyzes cells from the patient’s blood, without the need of a microscopy slide.

Cells are visualized morphologically intact after immuno-fluorescent of Fluorescence In Situ Hybridization (FISH) staining by utilizing 3-D tomographic microscopy. Several million cells can be visualized also live, immobilized in life-sustaining hydrogel

ENRICHMENT-FREE rare cell detection and deep characterization

INTACT CELL visualization in a life-sustaining 3-D suspension

LIVE CELL visualization over long periods of time

SINGLE CELL isolation - intact and live 

3D-CULTURE of cells under continual visualization
