Percentage of total costs per category, assuming clinic load of 50 patients initiated per month.
Results: The largest portion of the cost comes from the Cartridge/Test Strip. This category represents 60% of the cost of POC CD4 count, 74% of the costs of POC HIV VL, and 92% of the cost of POC Creatinine.

Sensitivity analysis: Cost to clinic per ART patient initiated and monitored over 5 or 10 years with varying patient volumes (2017 US$).

Percent contribution of each cost category to total costs of monitoring over 5 years at various clinic sizes.
The largest portion of the total cost at all clinic patient loads is the Cartridge/Test Strip. As patient loads increase and Instrument/Supplies percentage per patient decreases, Cartridge/Test Strip cost becomes a higher percentage of the total cost.
