Abstract：
:Leukotrienes constitute a class of potent biological mediators of inflammation and anaphylaxis. However, their routine assay in various biological fluids is restricted by the complexity of the methodology. Previously this could only be performed by research laboratories with high pressure liquid chromatography and radioimmunological capabilities. The recent availability of kits for immunoenzymatic assay of leukotrienes offers a new tool for clinical laboratories provided the limitations of the method are understood. We suggest a simplified methodology for direct urinary LTE4 detection and outline a number of areas of concern encountered with this method.
