Amphetamines Analysis, Serum
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
|Test ID||Reporting Name||Available Separately||Always Performed|
|FSAC||Amphetamines, GC/MS Confirm||No||No|
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
If the Serum Amphetamine Analysis is positive, then the Amphetamines, GC/MS Confirm (FSAC) will be performed at no additional charge.
Immunoassay (IA) – Screen
Gas Chromatography/Mass Spectrometry (GC/MS) – Confirmation; if applicable
Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name

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.
Submit only 1 of the following specimens:
Draw blood in a green-top (sodium heparin) tube(s), plasma gel tube is not acceptable. Spin down and send 7 mL sodium heparin plasma refrigerated in a plastic vial.
Draw blood in a plain red-top tube(s), serum gel tube is not acceptable. Spin down and send 7 mL of serum refrigerated in a plastic vial.
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.
Warm OK; Cold OK
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
|Varies||Refrigerated (preferred)||14 days|
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.
This specimen was screened by Immunoassay. Any positive result is confirmed by Gas Chromatography with Mass Spectrometry (GC/MS).
The following threshold concentrations are used for this analysis:
Drug Screening Confirmation
Amphetamines 50 ng/mL
Amphetamine 10 ng/mL
Methamphetamine 10 ng/mL

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 through Sunday
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.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
7 - 9 days
Performing Laboratory Location The location of the laboratory that performs the test
Medtox Laboratories, Inc.
CPT Code Information Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Medical Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.
82145-Quantitation (if appropriate)
LOINC® Code Information Provides guidance in determining the Logical Observation Identifiers Names and Codes (LOINC) values for the result codes returned for this test or profile.
