Breathalyzers are widely used by law enforcement, and in workplaces to detect alcohol levels in an individual’s breath. While they serve as an essential tool for initial screening, a key question remains—can breathalyzers be used for confirmatory testing?
The answer depends on the type of breathalyzer used and the purpose of the test.
Screening breathalyzers such as those from Andatech are effective for detecting the presence of alcohol and estimating BAC.
But confirmatory testing, especially for legal or disciplinary actions, typically requires more advanced testing methods, such as a blood analysis or through an evidential breath testing device.
Andatech breathalyzers provide highly accurate readings for initial screening but are not classified for evidential testing.
The difference between screening and confirmatory testing
To understand the role of breathalyzers in alcohol testing, it is essential to differentiate between screening and confirmatory tests:
-
Screening tests:
- Serve as a first-line detection tool to determine the presence of alcohol.
- Are quick, non-invasive, and widely used in workplaces, transportation sectors, and roadside law enforcement.
- May result in false positives or variability due to factors like residual mouth alcohol, poorly maintained devices, contaminated mouthpieces, and more.
-
Confirmatory tests:
- Provide definitive evidence of alcohol consumption.
- Are required for legal, disciplinary, or medical purposes.
- Typically involve blood or advanced evidential breath analysis.
While breathalyzers are highly effective for preliminary testing, legal and regulatory bodies usually require a secondary test for confirmation before any punitive action is taken.

How breathalyzers work
Breathalyzers estimate Blood Alcohol Concentration (BAC) by analyzing the alcohol content in a person’s breath. The device works using one of the following technologies:
-
Fuel Cell Technology:
- Provides high accuracy and reliability.
- Commonly used in workplace and law enforcement breathalyzers.
-
Semiconductor Sensors:
- More affordable but may be less accurate.
- Suitable for personal use or low-volume workplace testing.
-
Infrared Spectroscopy (Used in Evidential Breath Testing):
- Found in law enforcement-grade devices.
- Can be used for confirmatory testing in legal proceedings.
Since Andatech workplace breathalyzers are not classified for evidential testing, companies should use them for preliminary alcohol detection and follow up with confirmatory testing when necessary.

Best practices for workplace alcohol testing
To ensure effective alcohol testing in the workplace, employers should follow these best practices:
-
Use Breathalyzers for Initial Screening:
- Implement regular and random breath alcohol testing for employees in safety-sensitive roles.
- Ensure breathalyzers are properly calibrated for accurate readings.
-
Follow Up with Confirmatory Testing When Needed:
- If a breathalyzer result is positive, confirm results for legal or disciplinary action.
- Maintain clear workplace policies on alcohol testing procedures.
- Educate Employees on Workplace Alcohol Policies:
- Provide training on the risks of alcohol consumption in workplace settings.
- Encourage a zero-tolerance culture where safety is a top priority.
- Invest in Reliable Testing Equipment:
- Choose accurate, high-quality breathalyzers for workplace safety initiatives.
- Work with trusted providers to ensure compliance with testing best practices.
Ensuring Accurate Alcohol Testing in the Workplace
Breathalyzers play a vital role in workplace safety by detecting alcohol consumption quickly and efficiently. However, for confirmatory testing, employers must rely on secondary tests like blood or urine analysis to meet legal and regulatory standards.
