Official Description

Glutethimide

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82980 refers to a laboratory test specifically designed to measure the level of glutethimide in biological samples such as urine and serum. Glutethimide is a potent hypnotic sedative that is commercially available under the brand name Doriden. Although it has sedative properties, glutethimide is rarely prescribed for legitimate medical purposes. Instead, it is more commonly associated with recreational use, where individuals may take it to enhance the effects of other medications, particularly narcotic analgesics like codeine. The testing for glutethimide is often part of panel tests that utilize advanced techniques such as gas chromatography-mass spectrometry (GC-MS) for qualitative drug screening. In cases where glutethimide is detected during these screenings, a quantitative analysis may be conducted to determine the specific concentration of the substance in the sample. This testing is crucial for monitoring potential misuse and ensuring patient safety in clinical settings.

1. Indications

The laboratory test for glutethimide is indicated in specific scenarios where monitoring of this substance is necessary. The following conditions warrant the performance of this test:

  • Drug Screening The test is utilized in qualitative drug screening panels to detect the presence of glutethimide in urine and serum samples.
  • Substance Abuse Evaluation It is indicated for evaluating potential substance abuse, particularly in individuals suspected of using glutethimide recreationally or in conjunction with other narcotics.
  • Monitoring Therapeutic Levels Although rarely prescribed, if glutethimide is used therapeutically, monitoring its levels may be necessary to ensure patient safety and efficacy of treatment.

2. Procedure

The procedure for testing glutethimide involves several key steps to ensure accurate measurement and analysis. The following outlines the procedural steps:

  • Sample Collection A biological sample, typically urine or serum, is collected from the patient. Proper collection techniques must be followed to avoid contamination and ensure the integrity of the sample.
  • Sample Preparation The collected sample undergoes preparation, which may include centrifugation or other methods to isolate the components necessary for testing. This step is crucial for accurate analysis.
  • Gas Chromatography-Mass Spectrometry (GC-MS) The prepared sample is subjected to gas chromatography-mass spectrometry, a highly sensitive and specific analytical method. This technique separates the components of the sample and identifies glutethimide based on its mass-to-charge ratio.
  • Quantitative Analysis If glutethimide is detected during the qualitative screening, a quantitative analysis may be performed to determine the exact concentration of the substance in the sample. This step provides critical information regarding the level of glutethimide present.
  • Result Interpretation The results of the test are interpreted by qualified laboratory personnel, who will provide a report detailing the presence and concentration of glutethimide, if applicable.

3. Post-Procedure

After the glutethimide testing procedure, the following post-procedure considerations should be noted. Patients may not require any specific post-procedure care, as the test is non-invasive and does not involve any significant risks. However, it is essential to communicate the results to the patient and any relevant healthcare providers. If glutethimide is detected, further evaluation may be necessary to assess potential substance abuse or to adjust any therapeutic regimens if applicable. Continuous monitoring may be recommended for individuals with a history of substance use to ensure safety and compliance with treatment protocols.
