Product Information

Accurate Testing for Alcohol Misuse Detection


Overview of the Test

The Carbohydrate-Deficient Transferrin (CDT) Test is a reliable blood test used to detect chronic and excessive alcohol consumption.  Because it checks alcohol use over the previous 2-3 weeks, it is more useful than blood or urine alcohol tests that only check for alcohol use over the previous 1-2 days. The CDT test measures the level of the CDT protein that rises with prolonged alcohol misuse. It is ideal for people about to have a DVLA medical so that they can go into it with confidence knowing their result. It is also used for personal, legal, or workplace purposes. Results are available within 5 working days*, ensuring prompt and confidential reporting.


Why It Would Be Used

The CDT Test is designed for individuals and organisations requiring alcohol misuse detection:

  • DVLA: Used in DVLA medicals to decide on reinstating a person's driving license
  • Legal Purposes: Provides admissible evidence for court cases or legal compliance.
  • Workplace Testing: Ensures adherence to occupational health and safety standards.
  • Personal Health Monitoring: Tracks alcohol consumption to support recovery or medical evaluations.

With a focus on accuracy and discretion, this test ensures reliable insights into long-term alcohol use.


How It Works

The CDT Test detects excessive alcohol consumption typically over the past 2–3 weeks. Elevated CDT levels indicate chronic heavy drinking, providing a clear indicator of misuse. Please note that the CDT protein is normally found in the body so its value can never be zero. It's level rises in response to increased alcohol consumption.

Proof of ID Requirement

To ensure compliance and traceability, you must provide valid photo ID (e.g., passport or driving licence) during your appointment. This ensures results meet legal and professional standards.

Please note that copies of IDs or those shown on mobile phones are not accepted.


Results

Results are processed within 5 working days* and securely delivered via Email. In our experience, it's important to have your CDT test well before your DVLA medical to avoid undue anxiety. All results are supervised by a doctor before being issued.

Please note that results cannot be given over the phone as the identity of the caller cannot be verified.

*Note: Turnaround time may vary slightly depending on sample collection time.
