Overview:

Appropriate test to rule out acute intermittent porphyria (AIP) and other acute attack types of porphyrias associated with neurologic and/or psychiatric symptoms. Detect porphyrias and porphyrinurias. Acute intermittent porphyria is characterized by excretion of porphobilinogen and delta aminolevulinic acid in urine during acute attacks, but not during latency. Increased urine values are seen in the intoxication porphyrias (heavy metals, halogenated solvents, certain drugs).
