Reference Intervals
Chromatographic pattern to indicate type of porphyria.
For adequate screening tests for porphyria we require:
Blood: 2-5 ml heparinised blood (T34)
Urine: 10-15 ml fresh random specimen
Faeces: A stool minimum 10 g (walnut size)
Specimens should be wrapped in foil, placed in a paper bag and not exposed to direct sunlight.
