Aminolevulinic Acid (ALA), Random Urine
Also known as: U ALA RAND
Use
This test evaluates for suspected aminolevulinic acid dehydratase deficiency (ADP) porphyria or hereditary tyrosinemia. Increased ALA concentration can be associated with exposure to alcohol, lead, and various other agents. Massive elevation of ALA occurs in acute porphyrias and hereditary tyrosinemia.
Special Instructions
Refrain from alcohol consumption 24 hours prior to collection. Specimen preservation with acid or base may interfere with results. If collected urine will be used for additional testing, remove the ALA aliquot before adding any acid or base preservatives.
Limitations
The test may not provide accurate results if specimen preservation involves acid or base. Stability is limited at ambient conditions, and various factors such as alcohol or lead exposure can influence ALA concentration.
