چکیده
The porphyrias are uncommon disorders of haem biosynthesis and their eVective management requires prompt and accurate diagnosis. This article describes methods for the determination of urinary porphobilinogen, urinary and faecal total porphyrins, and total porphyrins in erythrocytes and plasma that are suitable for use in non-specialist laboratories. The selection and interpretation of these methods, and the indications for further, more specialised, investigation are discussed. (J Clin Pathol 2001;54:500–507)

Case Report The first step in the investigation of suspected acute porphyria is measurement of urinary s-aminolaevulic acid (ALA) and porphobilinogen (PBG). When raised, acute porphyria is suggested. These tests do not discriminate between the various types of porphyria, and they return to normal limits within 7-10 days of onset of symptoms. Genetic analysis subsequently confirmed a previously ...
