What condition is diagnosed using Sudan stain?

The condition diagnosed using Sudan stain is steatorrhea, which refers to the presence of excess fat in the feces. Sudan stain is a laboratory technique specifically designed to identify lipids and fats in biological samples.

When a sample of stool is treated with Sudan stain, any fats present will absorb the dye, allowing them to be visualized under a microscope. On the other hand, the other choices, while relevant to health and medical lab testing, are not diagnosed using this specific staining technique. Diabetes is generally diagnosed through glucose tests, hemolysis involves examining blood samples for the breakdown of red blood cells, and anemia typically requires complete blood counts and iron studies rather than a fat stain. Therefore, steatorrhea is accurately diagnosed with Sudan stain due to its unique chemical properties that highlight fat content.
