Segmentation by type isolates three technological families that shape the competitive structure of the rapid testing market. Antigen‑based kits dominate with an estimated 55 % share, owing to their low production cost, rapid results (typically 15 minutes), and suitability for mass testing; however, sensitivity varies with viral load, influencing procurement strategies. Molecular rapid assays—principally RT‑LAMP and accelerated RT‑PCR formats—contribute about 30 % of revenue, offering higher analytical sensitivity and specificity while retaining a turnaround under one hour, which justifies a premium price point for clinical and high‑risk environments. Serology rapid tests, detecting IgM/IgG antibodies, hold the smallest slice at roughly 15 %, reflecting limited utility for acute infection diagnosis but valuable for epidemiological surveillance and post‑vaccination monitoring. Each type’s share reflects a trade‑off among cost, performance, and intended use, thereby informing manufacturers’ R&D allocation and investors’ portfolio decisions.
