CyPath® Lung in Practice: From Uncertainty to Clarity and Confidence

American Cancer Society National Lung Cancer Roundtable, December 7, 2025 Author: Gordon Downie, MD, PhD, bioAffinity Technologies Chief Medical Officer.   Three patient case studies in which CyPath® Lung, a noninvasive sputum-based flow cytometry test, successfully identified Stage 1A lung cancer in patients with atypical and diagnostically challenging presentations.   Background: The clinical burden of competent pulmonary nodule identification and definitive diagnosis is increasingly common. This is especially true in complex cases with conflicting results from diagnostic tests and procedures. Clinicians are tasked with in-depth difficult discussions with their patients when risk calculators, imaging, genetic and other adjuvant testing information points definitively either at benign or malignant process. Clinical presentations with unusual risk, imaging, age, functionality or newer adjuvant...

Economic Evaluation of a Novel Lung Cancer Diagnostic in a Population of Patients with a Positive Low-Dose Computed Tomography Result

Journal of Health Economics and Outcomes Research, September 17, 2024 Authors: Morris M.J., Habib S.A., Do Valle M.L., Schneider J.E. Abstract Background: Early detection of lung cancer is crucial for improving patient outcomes. Although advances in diagnostic technologies have significantly enhanced the ability to identify lung cancer in earlier stages,...

Porphyrin-Modified Beads for Use as Compensation Controls in Flow Cytometry

JoVE Journal, March 24, 2023 Authors William Bauta, Marcia Grayson, Rossella Titone, Jennifer Rebeles, Vivienne I. Rebel Abstract Flow cytometry can rapidly characterize and quantify diverse cell populations based on fluorescence measurements. The cells are first stained with one or more fluorescent reagents, each functionalized with a different fluorescent...

The CyPath® Lung Flow Cytometry Test is sold by Precision Pathology Laboratory Services, a bioAffinity Technologies company,  as a Laboratory Developed Test (LDT).

CyPath® Lung is a non-invasive test that assists clinical decision-making in lung cancer patients whose low-dose computed tomography (LDCT) has demonstrated a suspicious finding.

The test reveals the lung micro-environment by automated analysis of sputum using flow cytometry to characterize cell populations indicative of cancer in the lung.
