HPLC: high-performance liquid chromatography; PADs/aPADs: paper analytic devices/antibiotic paper analytical devices; SF: substandard or falsified.
The table presents annual average costs over 3 year model runs. Across all scenarios, the numbers of overall treatments (SF treatments + legitimate treatments) are kept constant. The PADs/aPADs with HPLC scenario draws three different samples over 3 years, and is thus able to detect and remove more SF amoxicillin compared to other scenarios.
