Treat with Sudan IV stain solubilized in organic solvents. Within the plaque, Sudan IV, a fat-soluble diazo dye having high affinity for triglycerides and cholesterol esters of lipoproteins, moves from the organic solvent phase and binds to the LDLs’ hydrophobic core of lipids, forming stable complexes. Wash away excess stain using ethanol.Sudan IV is a red dye. The Sudan indicator test begins by taking a sample of food and, if it is a solid, making it liquid by crushing it with a pestle and mortar and mixing it with water. The sample is then placed in a test tube, and a few drops of the indicator are added. The test tube is then gently swirled so that the dye and sample mix.sudan iv test forMicroscopic examination of stool using Sudan stain to detect fat is the best screening test for fat malabsorption.
