Breathalyzer tests for measuring alcohol in breath are a recommendable method oftesting blood or breath alcohol levels.  Disposable alcohol test kits and electronic alcohol breathalysers are usefulfor use in businesses, by healthcare professionals or for home use.  Most people use them to test against the drink drive limit. In the UK this is 80mg/dl or 0.08% BAC (blood alcohol concentration).

Electronic Breath Alcohol Testing Units

Electronic breathalysers are more cost effective if you are screening for alcohol on a regular basis. Breathalyzers use disposable mouthpieces for accurate testing.

Breathalyzer Tests - A very simple commercial version of the “blow in the bag” Breathalyser used by the British Police.
     
The Home Office Approved personal Breathalyzer testing units are a portable modification of the basic roadside breath alcohol test used by the British Police Forces for a long time. It uses yellow crystals which turn green in the presence of any alcohol in breath in order to test patients to a pre-determined level.

This is the disposable product repeatedly used when carrying out pre-employment, random or accident based workplace employee drug and alcohol screening. 

The most accurate time to use these tests is in the morning to see if you are under the limit enough to drive, this is because if you use them while you are still consuming alcohol the test won’t be accurate because alcohol will be in your stomach but not yet in your blood stream or breath, so you could be under the limit when you test yourself but 10 minutes later, you could be over the limit.
