WebPorphyrin tests measure the level of porphyrins in your blood, urine (pee), or stool (poop). Your body uses porphyrins to make heme. Heme is part of hemoglobin , which is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. It's normal to have a small amount of porphyrins in your blood and other body ... WebUrine porphyrins are commonly measured for screening for PCT and other porphyrias. But it must be remembered that increases in urinary porphyrins can occur in medical conditions other than Porphyria, especially in conditions that affect the liver and bone marrow. WebWhat does it mean if your Heptacarboxyporphyrin result is too high?
