Extended Data Table 5.

Estimated cost of V. cholerae culture in US dollars (USD)

This table includes rounded, estimated costs of reagents and materials required to perform culture of V. cholerae from suspected case stool samples stored in agar stabs, as solicited by expert information. Our model assumption of $13 USD per sample falls within the range presented in the table. The costs listed in [B] are the estimated total costs for a box or bottle of reagent or material. The term ‘reagent unit’ [C-E] refers to the number of preparations that can be made from the amount of reagent or material listed in [A]. Cost per reagent unit [D] is calculated as the Reagent/ Material cost [B] divided by Reagent units available [C]. In some cases, multiple preparations may be required to test a single sample [E]. Lower and upper estimated costs per sample [F-G] are calculated as the product of Cost per reagent unit [C] and Reagent units used per sample [E]. These estimates do not take into account the costs of plastic consumables or running a laboratory.
