Official Description

Flurazepam

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82742 refers to a laboratory test specifically designed to measure the concentration of Flurazepam in the bloodstream. Flurazepam is a medication classified as a benzodiazepine, which is commonly prescribed under the brand name Dalmane. This medication is primarily utilized for the treatment of insomnia, as it effectively lowers brain activity, facilitating the onset of sleep. In addition to its sedative properties, Flurazepam is also beneficial in managing anxiety, relaxing skeletal muscles, and reducing seizure activity. One notable characteristic of Flurazepam is its long half-life, which allows it to remain detectable in the bloodstream for up to four days following ingestion. This extended duration of action makes Flurazepam particularly useful when administered the night before a medical or dental procedure, as it not only promotes sleep but also helps to alleviate anxiety that may be experienced the following day. The testing process for Flurazepam involves obtaining a blood sample through a procedure known as venipuncture, which is reported separately. The analysis of the serum or plasma is conducted using a sophisticated technique called quantitative liquid chromatography-tandem mass spectrometry, ensuring accurate measurement of the drug's levels in the patient's system.

1. Indications

The laboratory test for Flurazepam is indicated for several specific conditions and circumstances, primarily related to its use as a medication. The following are the explicit indications for performing this test:

  • Insomnia The test is performed to monitor the levels of Flurazepam in patients who are prescribed this medication for the treatment of insomnia.
  • Anxiety Management It is indicated for patients using Flurazepam to help control anxiety symptoms, ensuring that the medication is within therapeutic levels.
  • Muscle Relaxation The test may be necessary for individuals who require muscle relaxation as part of their treatment plan, allowing for appropriate dosing of Flurazepam.
  • Seizure Activity Patients experiencing seizure activity may be tested to confirm that Flurazepam levels are adequate for therapeutic effect.
  • Pre-Procedure Anxiety The test is indicated for patients who have taken Flurazepam the night before a medical or dental procedure to assess its effectiveness in alleviating anxiety.

2. Procedure

The procedure for testing Flurazepam involves several key steps that ensure accurate measurement of the drug's concentration in the bloodstream. The following procedural steps are explicitly outlined:

  • Step 1: Patient Preparation Prior to the test, the patient may be instructed to refrain from certain medications or substances that could interfere with the results. It is essential to gather a complete medication history to ensure accurate interpretation of the test results.
  • Step 2: Venipuncture A blood sample is obtained through a process known as venipuncture. This involves the insertion of a needle into a vein, typically in the arm, to collect the necessary blood sample for analysis. This step is crucial as it provides the specimen needed for the subsequent testing.
  • Step 3: Sample Handling Once the blood sample is collected, it is processed to separate the serum or plasma from the cellular components. Proper handling and storage of the sample are vital to maintain its integrity for accurate testing.
  • Step 4: Laboratory Analysis The serum or plasma is then subjected to quantitative liquid chromatography-tandem mass spectrometry. This advanced analytical technique allows for precise measurement of Flurazepam levels, providing reliable results that can be used for clinical decision-making.
  • Step 5: Result Interpretation After the analysis is complete, the results are interpreted by qualified laboratory personnel or healthcare providers. The findings will indicate the concentration of Flurazepam in the patient's system, which can inform treatment adjustments or further clinical management.

3. Post-Procedure

After the procedure, there are several considerations for both the patient and healthcare providers. The patient may experience minor discomfort at the venipuncture site, which typically resolves quickly. It is important to monitor the patient for any adverse reactions, especially if they are on Flurazepam or other medications that may affect their response. The results of the Flurazepam test will be communicated to the prescribing physician, who will use this information to assess the effectiveness of the treatment plan. Depending on the results, the physician may decide to adjust the dosage of Flurazepam or explore alternative treatment options. Additionally, patients should be advised to follow up with their healthcare provider to discuss the results and any necessary changes to their medication regimen.
