The PCT (Procalcitonin) assay kit is an *in vitro* diagnostic (IVD) reagent product designed for the quantitative detection of procalcitonin concentrations in human samples, such as serum and plasma. Procalcitonin is a precursor protein to calcitonin, produced by the C cells of the thyroid gland. While its concentration is extremely low (<0.05 ng/mL) in healthy individuals, it rises significantly during bacterial infections—particularly in cases of sepsis, pneumonia, and meningitis. Consequently, it serves as a critical biomarker for distinguishing between bacterial and viral infections, assessing the severity of sepsis, and guiding antibiotic therapy. PCT assay kits operate based on immunological principles, utilizing the specific binding reaction between antibodies and PCT antigens to achieve precise quantitative measurement of PCT concentrations within a sample.

The core raw materials for PCT assay kits include: anti-PCT monoclonal or polyclonal antibodies (the most critical biological component, determining the reagent's sensitivity and specificity); magnetic beads or microspheres (serving as solid-phase carriers in chemiluminescence and immunochromatography methods); enzyme labels (such as Horseradish Peroxidase [HRP] and Alkaline Phosphatase [AP]); calibrators and quality control materials (standard substances containing recombinant PCT protein); buffers and stabilizers (maintaining the pH and protein activity of the reaction system); and coated plates or test cards (solid-phase substrates made of materials such as PVC or nitrocellulose [NC] membranes). Among these components, the antibody raw material represents the core component with the highest cost share. The research, development, and production of high-quality monoclonal antibodies involve significant technological barriers; manufacturers often rely on either imports or independent development—factors that directly impact the assay kit's detection performance and batch-to-batch consistency. In terms of cost structure, biological raw materials (antibodies, antigens, and enzymes) typically account for 35–45% of total costs, making them the most cost-sensitive component. Solid-phase carriers—such as magnetic beads and microspheres (accounting for approximately 15–20%)—are particularly critical for chemiluminescence reagents. Calibrators and quality control materials (accounting for approximately 10–15%) require high-purity recombinant proteins. Packaging materials and injection-molded components account for approximately 8–12%, while production quality control and cold-chain storage/transportation account for about 10–15%; the latter incurs significant costs due to the temperature sensitivity of biological reagents. The remaining costs consist of R&D amortization, regulatory registration and certification, and brand premiums. Through independent antibody development and large-scale manufacturing, domestically produced reagent kits are gradually reducing their reliance on imported raw materials; however, in the high-end chemiluminescence sector, imported brands continue to maintain a dominant position, leveraging their advantages in antibody patents and instrument platforms.
