A short description of the method used to perform the test
Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS)
NY State Available
Indicates the status of NY State approval and if the test is orderable for NY State clients.
Lists a shorter or abbreviated version of the Published Name for a test
Tiagabine (Gabitril), S
Lists additional common names for a test, as an aid in searching
Describes the specimen type validated for testing
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Draw blood in a plain red-top tube(s), serum gel tube is not acceptable. Spin down and send 3 mL of serum refrigerated in a plastic vial.
Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory

Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
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.
Report Limit: 5.0 ng/mL
Reference Range: <235.0 ng/mL
Therapeutic and toxic ranges have not been established.
Peak concentrations are expected at 45 minutes post dose; steady state is generally attained within 2 days.
Observed tiagabine concentrations in clinical trials (30 â€“ 56 mg/day): <1 â€“ 234 ng/mL.
Measured tiagabine concentrations, post marketing (95% confidence interval): 0 â€“ 440 ng/mL.
Note: The 95% confidence interval for tiagabine concentrations determined by MEDTOX Laboratories will be updated periodically as more information becomes available.
Indicates whether the report includes an additional document with charts, images or other enriched information
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
2 to 6 days
Performing Laboratory Location
Indicates the location of the laboratory that performs the test
Medtox Laboratories, Inc.
