Types segmentation classifies household kits by analytical technology, chiefly antigen rapid tests, PCR home kits, saliva‑based molecular assays, and antibody detection kits. Antigen rapid tests dominate with an estimated 55 % share, owing to their low cost, ease of use, and results within 15 minutes, which drives high unit sales across all application segments. PCR home kits, comprising about 30 % of the market, offer laboratory‑grade sensitivity and are preferred for travel clearance and confirmatory testing; their higher price and requirement for mail‑in processing limit penetration but generate higher average revenue per unit. Saliva‑based molecular assays, a newer entrant, hold roughly 10 % and appeal to families with children who cannot tolerate nasal swabs, supporting incremental growth in the asymptomatic screening niche. Antibody detection kits, occupying the remaining 5 %, serve post‑infection monitoring rather than acute diagnosis and therefore contribute marginally to total volume. The distribution of these test types underpins the overall Household COVID-19 Testing segmentation and informs supply‑chain allocation.
