Special instructions

Wrap all samples in foil to protect from light. Clinical details required: was the patient symptomatic of Porphyria when sample taken and nature of symptoms. Please ensure that all samples are posted together to the lab.

Porphyria is an inherited disorder in which the body produces too much of the chemical porphyrin. Porphyrin is essential to make the part of blood that carries oxygen (heme). Any circulating porphyrin the body doesn't use is excreted in urine and stool.

When the body produces and excretes too much porphyrin, as happens with porphyria, not enough heme remains to keep a person healthy. Porphyria affects either the nervous system or the skin.

Attacks can be triggered by drugs (barbiturates, tranquillisers, contraceptive pills, sedatives) as well as chemicals, certain foods and exposure to the sun.
