The types segment classifies GFAP kits according to assay format, encompassing ELISA kits, Luminex multiplex assays, and Western blot kits. ELISA kits dominate the landscape, offering high‑throughput, quantitative readouts suitable for both research and diagnostic laboratories; they represent the largest share due to established validation protocols and cost‑effectiveness. Luminex multiplex platforms, while constituting a smaller portion of the market, provide simultaneous detection of GFAP alongside complementary biomarkers, appealing to institutions seeking comprehensive neuro‑inflammatory panels. Western blot kits occupy a niche, primarily used for confirmatory protein expression analysis in mechanistic studies, and thus generate modest revenue relative to the other formats. This type‑based market taxonomy clarifies how assay selection influences procurement decisions, pricing elasticity, and overall market growth, as each format aligns with distinct workflow requirements and budget constraints across end‑users.
