As porphyrins are light sensitive, all specimens must be kept in the dark; usually this is done by wrapping the specimen in foil. Porphyrin profile (HPLC analysis) of urine or faecal porphyrins will be done automatically if the total porphyrins are increased.

WebNotes. The porphyrias are a group of rare inherited or acquired disorders in which a deficiency in one of the enzymes involved in porphyrin synthesis results in decreased formation of haem, and accumulation of excess porphyrins or their precursors. Weblaboratories, porphyrin screening tests were always based on the extraction of porphyrins into an organic solvent followed by visual inspection for red fluorescence under an ultra violet lamp. Screening for excess porphobili nogen (PBG) utilised some form of Ehrlich's reagent (4-dimethylaminobenzaldehyde in acid). Results were only included ...
WebDiagnostically significant changes in porphyrin concentration are unlikely to occur within 36 hours at room temperature if protected from light, allowing samples to be mailed to an expert laboratory. Samples are stable for many months at -20° C. For plasma porphyrin analysis, 5mL EDTA-anticoagulated blood, protected from light, is recommended.

AIP manifests itself by abdomen pain, neuropathies, and constipation, but, unlike most types of porphyria, patients with AIP do not have a rash.
WebPlasma porphyrins are more light sensitive and often less elevated than in other cutaneous porphyrias, especially with mild disease. Urinary porphyrins and porphyrin precursors are normal. Hepatic complications of EPP are heralded by abnormal liver tests and increasing levels of erythrocyte and plasma protoporphyrin.
