Used in research settings to detect and quantify levels of monoethylhexyl phthalate (MEHP), a primary metabolite of diethylhexyl phthalate (DEHP), in biological samples such as urine, serum, or plasma. The kit supports studies on human exposure to phthalates, commonly found in plastics, by measuring biomarkers of exposure. It is widely applied in environmental health and toxicology research to assess the potential endocrine-disrupting effects of phthalates, monitor population exposure levels, and investigate links to reproductive and developmental health issues. The ELISA format allows for high-throughput, sensitive, and specific detection without the need for complex instrumentation.
