New Case Study: bioAffinity Technologies’ CyPath® Lung Provides Actionable Results and Helps Patient Avoid Costly, Invasive Procedures

Key Terms

pulmonary nodules medical

Pulmonary nodules are small, round or oval spots found in the lungs on X-rays or CT scans; they can be scar tissue, infections, or early tumors. For investors, these findings matter because they can trigger diagnostic follow-up, treatment decisions, drug or device demand, clinical trial activity, regulatory scrutiny, and potential changes in healthcare costs or company valuations—think of a nodule like a small warning light that may or may not signal a serious engine problem.

bronchoscopy medical

Bronchoscopy is a medical procedure that uses a thin, flexible tube with a light and camera to look inside the airways and lungs, and sometimes to take samples or remove small obstructions. For investors, bronchoscopy matters because demand for the procedure, the devices used, and related drugs or diagnostic tests can affect sales, clinical trial progress, reimbursement and regulatory decisions—think of it like using a camera to inspect and fix a building’s hidden plumbing, revealing problems and creating business opportunities.

biopsy medical

A biopsy is a medical procedure that removes a small piece of tissue or cells so a doctor can examine them under a microscope to see if disease, such as cancer or an infection, is present. For investors, biopsy results can change the outlook for drugs, diagnostics and medical devices—think of it like sampling a bite of food to decide whether the whole dish is safe; positive or negative findings can affect clinical trial success, approval chances, market demand and reimbursement decisions.

low dose CT medical

Low dose CT is a medical imaging scan that uses computed tomography technology with a reduced amount of X-ray radiation to produce detailed pictures of the body, often used for screening lungs and other organs. It matters to investors because lower-radiation scans can increase patient acceptance and screening volumes, influence demand for specialized scanners and software, and affect regulatory approvals and reimbursement—factors that shape healthcare providers’ purchasing and revenue trends.

specificity medical

Specificity measures how well a diagnostic test or screening correctly identifies people who do not have a condition — the percentage of healthy cases the test labels as negative. Think of it as a smoke alarm that stays quiet when there’s no fire; high specificity means fewer false alarms. For investors, specificity affects regulatory approval, clinical adoption, follow-up costs, and the perceived reliability and market potential of medical products.

accuracy technical

Accuracy is how close a reported number, measurement or statement is to the true value or reality; think of it like a ruler that gives the correct length or a GPS that points to the right address. Investors care because accurate data—financial figures, clinical results, regulatory information or performance metrics—lets them judge risk and make decisions with confidence; unreliable accuracy can lead to wrong valuations, unexpected losses or regulatory trouble.

CyPath® Lung improves diagnostic clarity in patients with multiple lung nodules

In this case study, CyPath® Lung “Unlikely Malignancy” result supported physician’s decision to wait before ordering an invasive lung biopsy

In a clinical study, noninvasive CyPath® Lung test demonstrated 92% sensitivity, 87% specificity and 88% accuracy for detecting lung cancer in small nodules less than 20 millimeters

SAN ANTONIO--(BUSINESS WIRE)-- bioAffinity Technologies, Inc. (Nasdaq: BIAF; BIAFW), a biotechnology company advancing noninvasive diagnostics for lung cancer and other lung diseases, today released a new clinical case study that highlights the benefit of adding CyPath® Lung, a noninvasive test for lung cancer, to the diagnostic pathway for a high-risk patient with multiple pulmonary nodules.

The patient is a 71-year-old former 20-pack-year smoker with a history of pneumonia in the right lower lobe. His current medical condition includes obesity and mild restrictive lung disease. Low dose CT scans revealed scattered pulmonary nodules, with one measuring 7 millimeters (mm), a size that has a greater potential for being cancerous and often leads to invasive bronchoscopy or biopsy.

“Multiple small nodules in a high-risk patient pose a diagnostic challenge, which can be exacerbated by the patient’s understandable anxiety about a potential cancer,” said Daya Nadarajah, MD, the patient’s pulmonologist. “In this case, the patient’s CyPath® Lung result was negative, indicating a low likelihood of malignancy, and together both the patient and I were comfortable in waiting for a follow-up CT scan in three months.”

The follow-up scan in October 2025 showed the suspicious nodules in the right upper lobe had resolved, indicating benign inflammation, and a small nodule located in the fissure between the upper and lower right lobes remained unchanged.

“This is another patient case study that illustrates how CyPath® Lung provides accurate results and greater confidence in pulmonary nodule management, supporting physician decision-making, reducing patient anxiety, and lowering healthcare costs by avoiding expensive, invasive and often risky procedures when they are not necessary,” said Gordon Downie, MD, PhD, Chief Medical Officer of bioAffinity Technologies.

About CyPath® Lung

CyPath® Lung by bioAffinity Technologies is a noninvasive test designed to aid in the early detection of lung cancer in patients at high risk for the disease. CyPath® Lung uses advanced flow cytometry and proprietary artificial intelligence (AI) to identify cell populations in patient sputum that may indicate malignancy. CyPath® Lung incorporates a fluorescent porphyrin that is preferentially taken up by cancer and cancer-related cells. In a clinical study, CyPath® Lung demonstrated 92% sensitivity, 87% specificity and 88% accuracy in detecting lung cancer in patients at high risk for the disease who had small indeterminate lung nodules less than 20 millimeters.

About bioAffinity Technologies, Inc.

bioAffinity Technologies, Inc. addresses the need for noninvasive diagnosis of early-stage cancer and other diseases of the lung and broad-spectrum cancer treatments. The Company’s first product, CyPath® Lung, is a noninvasive test that has shown high sensitivity, specificity and accuracy for the detection of early-stage lung cancer. CyPath® Lung is marketed as a Laboratory Developed Test (LDT) by Precision Pathology Laboratory Services, a subsidiary of bioAffinity Technologies. LDTs are overseen under the Clinical Laboratory Improvement Amendments (CLIA), administered by the Centers for Medicare & Medicaid Services. For more information, visit www.bioaffinitytech.com.
