High Performance 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
Bupropion and Metabolite, 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
Specimen Type: Serum
Specimen volume: 1 mL
Draw blood in a plain red-top tube(s), serum gel tube is not acceptable. Spin down and send 1 mL of serum frozen 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
Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis || Mild reject; Gross reject |
| Lipemia || Mild OK; Gross OK |
| Icterus || OK |
| Other || Polymer gel separation tube (SST or PST) |
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.
Reporting Limit determined each analysis.
Provides information to assist in interpretation of the test results
Maximum antidepressant response was observed at trough plasma concentrations of 50 – 100 ng/mL bupropion with virtually no response below 25 ng/mL.
Reported average bupropion peak plasma concentrations:
Adults: Single 100 mg IR – 120 +/- 10 ng/mL (Males):
150 +/- 10 ng/mL (Females)
Adults: Single 200 mg IR -220 +/- 20 ng/mL (Males):
270 +/- 20 ng/mL (Females)
Adults: Single 150 mg SR - 140 +/- 20 ng/mL
Juveniles: 100 mg/day SR for 2 weeks – 25 +/- 8 ng/mL
Juveniles: 200 mg/day SR for 2 weeks – 53 +/- 22 ng/mL
Specimens must be kept frozen. If specimens are not kept frozen, this may cause lower or negative values.
8 adults (Age 22 – 42) taking thrice daily 100 mg normal release bupropion for 2 weeks had an average peak plasma concentration of 1000 +/- 70 ng/mL hydroxybupropion.
Juvenile patients taking once daily, extended release bupropion for two weeks had the following peak plasma concentrations:
100 mg/day (n = 11), 450 +/- 210 ng/mL hydroxybupropion
200 mg/day (n = 8), 710 +/- 350 ng/mL hydroxybupropion

Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.
This test was developed and its performance characteristics determined by NMS Labs. It has not been cleared or approved by the U.S. Food and Drug Administration.
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 Clinic Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.
CPT codes are provided by the performing laboratory.
