Antigen rapid tests, nasopharyngeal PCR and saliva PCR to detect SARS-CoV-2: A prospective comparative clinical trial.

This study demonstrates that in resource-limited settings like Mozambique, Ag-RDTs are a highly cost-effective alternative to RT-PCR, costing approximately three times less per test ($11.60 vs. $39.20). Medical supplies emerged as the primary cost driver, accounting for over 50% of total expenses, while the impact of personnel and overhead costs remained secondary. The findings suggest that the most effective way for governments in LMICs to reduce testing expenditures is to focus on lowering the cost of medical supplies rather than shifting labor cadres. Ultimately, integrating affordable Ag-RDTs into national screening strategies provides a sustainable and efficient pathway for managing pandemic diagnostic needs in resource-scarce environments.
