Aminolevulinic Acid (ALA), Urine

Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Required Information: Total volume and duration.

Patient Preparation: Refrain from alcohol consumption 24 hours prior to collection. Increased ALA concentration is associated with exposure to alcohol, lead, and a variety of other agents. 

Collection Container/Tube: 24 hour urine collection container

Submission Container/Tube: aliquot tube.

Specimen Volume: 4 mL

Collection Instructions: Collect 24 hour urine, and maintain refrigerate during collection, submit 4 mL aliquot from urine in aliquot tube.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

1.2 mL
