Porphyrins and Porphobilinegens

Alternate Names

  • Porphyrin Tests

Porphyrins and porphobilinogens are enzymes necessary for the normal formation of the heme part of red blood cells. Heme is the blood component that carries oxygen to all tissues of the body for normal function. There are inherited deficiencies of the enzymes needed for the normal formation of porphyrins. This deficiency leads to high blood levels of porphyrins and porphobilinogens that spills over into the urine and can be then be measured. High urine levels are seen in people with porphyria, pellagra, liver diseases, or lead poisoning.
