Do you mean ketones? Ketones are a by-product of fat breakdown. When a person is not eating enough carbohydrates (bread, pasta, rice, potatos) for their energy needs the body starts using its fat stores for energy and ketones show in the urine. It may also be a sign of Diabetes. If I haven't answered the question you asked please ask as something different.
The test is positive only for ketones because it specifically reacts with ketone bodies present in the sample. This reaction produces a color change or another observable result that indicates the presence of ketones. Other substances in the sample do not interfere with this specific reaction, leading to a positive result only for ketones.
