Used in research settings to measure cortisol levels in porcine (pig) biological samples such as serum, plasma, or saliva. This kit enables scientists to assess adrenal function and stress responses in pigs, which is valuable in veterinary research, animal welfare studies, and agricultural science. It supports investigations into the effects of environmental stressors, nutrition, disease, and management practices on pig health and productivity. The assay is not for diagnostic use but serves as a tool for quantitative analysis in experimental studies.
