Types of Drive-through COVID-19 Testing are classified by the biological target and analytical platform, each influencing cost structure and throughput. The dominant Molecular (RT‑PCR) tests, performed on nasopharyngeal swabs, deliver the highest sensitivity and command the largest revenue share, roughly 55 % of the market, due to laboratory processing requirements. Antigen tests, also nasopharyngeal but delivering results within 15 minutes, occupy about 30 % as they enable rapid turnover despite lower sensitivity. Saliva‑based molecular assays, a growing sub‑type, represent 8 % by offering non‑invasive collection while maintaining PCR‑level accuracy. Antibody serology tests, used primarily for post‑infection surveillance, contribute around 5 % because they are not diagnostic for active infection. A niche point‑of‑care cartridge platform, integrating microfluidics for on‑site amplification, accounts for the remaining 2 %. Understanding these test‑type distributions clarifies the market taxonomy and guides investment in equipment, staffing, and supply‑chain logistics.
