Uroporphyrin is a type of porphyrin, a group of organic compounds essential for various biological functions. It is produced in the body during the breakdown of heme, a component of hemoglobin found in red blood cells. Uroporphyrin is primarily excreted in urine and can be measured to assess certain health conditions. Elevated levels of uroporphyrin in the urine may indicate disorders such as porphyria, a group of diseases that affect the production of heme. These conditions can lead to symptoms like abdominal pain, skin sensitivity, and neurological issues. Monitoring uroporphyrin levels can help in diagnosing and managing these disorders.
