|---|---|---|---|---|
| Primary | Serum/Plasma Presepsin Levels | Preoperatively, before appendectomy (single blood sampling). | Presepsin concentrations will be measured in preoperative peripheral venous blood samples using commercially available ELISA kits according to the manufacturer's instructions. Serum or plasma presepsin levels will be expressed in ng/mL (provisional unit, subject to confirmation based on the selected assay). The measurements will be used to evaluate systemic inflammatory responses and their association with the severity of acute appendicitis. | ClinicalTrials.gov |
| Primary | Appendix Tissue Presepsin Levels | During appendectomy (single tissue collection). | Presepsin levels will be measured in appendix tissue homogenates prepared from surgically removed appendectomy specimens using commercially available ELISA kits according to the manufacturer's instructions. Results will be normalized to total tissue protein content and expressed in ng/mg total protein (provisional unit, subject to confirmation based on the selected assay and normalization method). The measurements will be used to evaluate local inflammatory responses and their association with the severity of acute appendicitis. | ClinicalTrials.gov |
