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.
