Statistical Information
- Nationwide serology testing for SARS‑CoV‑2 antibodies: CDC’s commercial lab seroprevalence survey tested hundreds of thousands of U.S. serum samples using SARS‑CoV‑2 immunoassays between 2020–2022. Infection‑induced seroprevalence rose from 8.0% in November 2020 to 58.2% by February 2022, reflecting large-scale use of laboratory antibody assays for surveillance rather than diagnosis, and demonstrating sustained demand for high‑throughput immunoassay platforms.
- Early U.S. city-level SARS‑CoV‑2 seroprevalence: A CDC study across 10 U.S. sites in early 2020 found seroprevalence of 1.0% in the San Francisco Bay Area, 1.0% in Washington State, and 6.9% in the New York City metro area, based on enzyme immunoassays of remnant clinical specimens. These low early values implied significant future upside for coronavirus immunoassay testing volumes as the pandemic expanded.
- Near-universal antibody positivity by late 2023: CDC serology surveillance shows that by late 2023, over 95% of U.S. adults and about 90% of children had detectable SARS‑CoV‑2 antibodies from infection, vaccination, or both. These figures come from repeated large-scale immunoassay testing, demonstrating extensive penetration of coronavirus antibody assays into clinical labs and blood collection centers over the 2020–2023 period.
- Infection-induced seroprevalence increase in adults: Using commercial laboratory immunoassays, CDC estimated infection‑induced seroprevalence among adults aged 18–49 years increased from 36.5% to 63.7% between September 2021 and February 2022. Among children 5–11 years, infection‑induced seroprevalence rose from 44.2% to 77.3% in the same period, highlighting rapidly rising exposure and heavy utilization of SARS‑CoV‑2 immunoassays for population-level surveillance.
- Blood donor cohort serology testing scale and results: CDC and partners established a cohort of 142,758 repeat blood donors in July 2021, periodically testing donations with SARS‑CoV‑2 immunoassays. By mid‑2022, 96.4% of persons aged ≥16 years in this cohort had detectable antibodies from prior infection or vaccination, illustrating both very high serologic immunity levels and continued large-scale use of immunoassays in blood services.
- FDA emergency authorizations for COVID diagnostics: A cross‑sectional analysis of U.S. FDA Emergency Use Authorizations found 393 COVID‑19–related products authorized, including 329 diagnostic tests (84%), 54 medical devices (14%), and 10 drugs or vaccines (3%). Many diagnostics were serology or antigen immunoassays, showing rapid expansion of the coronavirus immunoassay and broader diagnostic test portfolio under EUA during the pandemic.
- Global COVID-19 diagnostics revenue and trajectory: Company- and filing-based analysis shows global COVID‑19 diagnostics revenue of USD 33.0 billion in 2023, projected to fall to USD 6.25 billion by 2030, a CAGR of −21.2%. While PCR and rapid antigen segments decline fastest, coronavirus immunoassay applications for seroprevalence, vaccine response, and specialized clinical use remain as smaller but ongoing revenue contributors.
- Total specimens in national CDC serology program: CDC’s national commercial laboratory serosurveillance program analyzed 1,469,792 serum specimens from clinical laboratories across 51 U.S. jurisdictions between October 2020 and February 2022 using FDA‑authorized immunoassays. Infection‑induced seroprevalence increased from 8.0% to 58.2%, demonstrating very large testing volumes and broad utilization of coronavirus immunoassays for repeated cross‑sectional surveillance.
- FDA total authorized serology and immune response tests: The FDA lists 74 antibody and other adaptive immune response tests for SARS‑CoV‑2 authorized under EUA, alongside 25 8 molecular tests and 17 antigen tests. This mix shows that immunoassays represent a significant minority of total COVID‑19 diagnostic authorizations, but still dozens of distinct commercial products competing in the coronavirus serology segment.
