Ambient, refrigerated or frozen to lab.

Remarks

Effective 8/1/13, the method used for amino acid screening now separates amino acids by high performance liquid chromatography instead of paper chromatography. Because of this, a separate "cystine screen" is no longer needed to rule out cystinuria or homocystinuria.

AMINOLEVULINIC ACID URINE

LAB356

Collect

24 hour or random urine. Refrigerate 24-hour specimens during collection.

Patient Preparation

Refrain from alcohol consumption 24 hours prior to collection.

Specimen Preparation

Transfer a 4 mL aliquot from a well-mixed 24 hour or random collection to an ARUP Standard Transport Tube. (Min: 1.2 mL)

Unacceptable Conditions

Body fluids other than urine.

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

Ambient: Unacceptable; Refrigerated: 4 days; Frozen: 1 month

Remarks

Record total volume and collection time interval on transport tube and test request form.

Notes

Increased ALA concentration is associated with exposure to alcohol, lead, and a variety of other agents.  Massive elevation of ALA occurs in the acute porphyrias and hereditary tyrosinemia.

Specimen preservation with acid or base is discouraged and may cause assay interference.  When collecting urine for additional tests that require acid or base preservation, the ALA aliquot should be removed prior to the addition of the acid or base.
