Alcohol Diagnostic Tests

Alcohol diagnostic tests are simple tools designed to help you understand whether alcohol is present in your body. Whether you’re planning to drive, heading back to work, or just want peace of mind, these tests offer a quick and convenient way to check your alcohol levels.

What are alcohol diagnostic tests?

Alcohol diagnostic tests measure the presence of alcohol in your system, most commonly through your breath. When alcohol is consumed, it enters your bloodstream and is partially exhaled through your lungs.

How do they work?

Most home alcohol tests are breath tests. You simply blow into a device, and a chemical reaction occurs that indicates the level of alcohol present. The result is usually displayed through a colour change or indicator scale.

When should you use one?

Alcohol diagnostic tests can be helpful in a range of everyday situations:

  • before driving the morning after drinking

  • after social events or celebrations

  • in workplace or safety-sensitive environments

  • when monitoring personal alcohol consumption

How accurate are they?

Alcohol diagnostic tests are designed to give a reliable indication of the presence of alcohol, but they are not a substitute for legal or police administered testing. 

Results can be influenced by timing (such as testing too soon after drinking), smoking, or even lighting conditions when reading the result.

At home tests can offer reassurance and help you make responsible choices when it matters most. 

If you are ever in doubt - don’t drive.
