Porphobiligen (PBG) - Urine

0 OFF

Porphobilinogen (PBG) is one of several types of porphyrins found in your body. Porphyrins help form many important substances in the body. One of these is hemoglobin, the protein in red blood cells that carries oxygen in the blood. Porphyrins usually leave your body through urine or stools. If this process does not occur, porphyrins such as PBG can build up in your body. Raised levels of porphobilinogen in urine is characteristic of an attack of acute porphyria

What is this test

Haemoglobin protein in red blood cells responsible for carrying oxygen in blood is a type of porphyrin which is formed from the intermediate Porphobilinogen (PBG). Porphyrins do not accumulate in the body and get excreted via urine or stool. In case they are not released from the body, there is a signal where they are getting accumulated. Hence, the PBG qualitative test diagnoses porphyria in the urine.
