Test ID: FALAU
Aminolevulinic Acid (ALA), Urine

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Yes

Method Name A short description of the method used to perform the test

Quantitative Ion Exchange Chromatography/Spectrophotometry

Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name

Aminolevulinic Acid (ALA), Urine

Aliases Lists additional common names for a test, as an aid in searching

ALA U FORWARD

Specimen Type Describes the specimen type needed for testing

Urine

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.

Collect 24 hour urine. Urine is to be protected from light and maintained refrigerate during collection.

Submit 4 mL aliquot from urine, frozen in an amber vial (MML Supply T192), protected from light.

 

Note:

  1. Required: Total volume and duration.
  2. Required: Protect from light.
  3. 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.  Massive elevation of ALA occurs in the acute porphyrias and hereditary tyrosinemia.
  4. 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.

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

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected

Hemolysis:

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

                               Salt Lake City, UT  84108

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday, Wednesday, Thursday, Saturday

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

1 - 4 days

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

3 - 11 days

Performing Laboratory Location The location of the laboratory that performs the test
