The Types segment classifies kits according to detection chemistry and format, with three dominant sub‑categories: immunochemical (FIT), guaiac‑based (gFOBT), and digital‑readout platforms. Immunochemical FIT kits dominate the market, contributing approximately 65 % of sales, because they target human hemoglobin, eliminate dietary interferences, and support quantitative results that align with clinical guidelines. Guaiac‑based kits, accounting for roughly 25 % of the market, remain in use in low‑resource settings due to lower unit costs, although they require dietary restrictions and exhibit lower specificity. Digital‑readout platforms, a newer niche representing about 10 % of revenue, integrate optical sensors and software algorithms to deliver automated interpretation, reducing operator error and enabling data integration with electronic health records. Each type influences overall market dynamics by affecting pricing structures, supply‑chain complexity, and adoption rates across the application categories described earlier. Precise knowledge of this market taxonomy supports strategic positioning and R&D investment decisions.
