Segmentation by type classifies diagnostic solutions according to underlying detection technology, each with distinct cost and performance profiles. Molecular assays—including real‑time PCR, digital PCR, and isothermal amplification (e.g., LAMP)—dominate the high‑value tier, offering the greatest analytical sensitivity and specificity for clinical and research settings. Immunoassays, primarily ELISA platforms, provide moderate throughput with quantitative readouts, serving both clinical laboratories and food‑testing facilities where batch processing is advantageous. Rapid antigen tests, often formatted as lateral‑flow devices, prioritize speed and point‑of‑care deployment, meeting the needs of outbreak response in community and field environments despite lower sensitivity. Emerging biosensor technologies, such as electrochemical and optical sensors, occupy a niche segment focused on real‑time monitoring and integration with digital health ecosystems. The proportional revenue contribution of each type aligns with its adoption rate across the application spectrum, reinforcing the market’s technology‑driven diversification.
