Alcohol tests detection periods

Testing for alcohol onsite has until recently been limited to measuring a real time alcohol level, either in saliva or breath. Options include single use breathalysers, digital breathalysers and saliva alcohol test strips. All work well at measuring the alcohol levels at the time of testing, but all are dependent on alcohol still being present in the system at the point of testing

Real time alcohol testing is appropriate for workplace and driving, but many healthcare tests need to detect alcohol use, not level. Looking back in time for alcohol exposure and heavy use, has until now been limited to laboratory test, either Liver function tests, measuring the elevated levels of enzymes associated with chronic alcohol use or hair strand analysis. Both take time and are expensive.

ETG alcohol test strips

Released in 2015 is the new ETG 80 hour urine alcohol screen. A simple dip test which will detect alcohol metabolite ETG for up to 72 hours after alcohol is last broken down, giving a possible window of detection of 80 hours.

ETG urine testing is ideal for healthcare compliance testing, insurance assessment testing and for workplace  environmental testing where zero alcohol policies exist (oil rig, gas rigs etc)

ETG is a specific breakdown product of ethanol, making it a specific test for ethanol (alcohol ) use.

Alcohol Testers

Breath Alcohol breathalyser 0.05%BAC

Breath alcohol testers

Screening for alcohol levels is now easier than ever. There are a complete range of single use testing kits which will allow instant screening to either a pre set cut off level or even give a semi quantitive indicator of the detected level.

The biotechnology in these tests is now well tested and most come with a full set of quality certification, ensuring a high level of accuracy if used to the manufacturers guidelines.

Most instant tests are actually set to Blood Alcohol Concentration (BAC) cut off levels. This can seem a little confusing when you are running a test on either saliva or breath, but with all the legislation referenced to BAC this actually makes sense. It also makes changing from saliva to breath screening a lot simpler, eliminating the need to cross reference different scales of measurement.

So what is available in todays market. Lets first look at the options for single use breath alcohol testers. All contain a chemical crystal, which on exposure to alcohol changes colour. By altering the chemical, this colour change can be made to occur only when a predetermined level of alcohol is reached. This makes it possible to set UK HSE breath alcohol testers to give positive results at alcohol levels of 0.02%BAC Scottish and French (EU) driving level cut of alcohol testers at alcohol levels of 0.05%BAC and UK England & Wales driving limit alcohol testers at alcohol levels of 0.08%BAC All three options are also available in triple test packs and double test packs with blow bags.

By altering the chemical slightly it is also possible to make it change colour to a greater degree at higher alcohol exposure levels. This makes it possible to turn the alcohol tester from a simple cut off positive or negative test, into a semi quantitive breath alcohol test. The darker the shade of colour change, the higher the alcohol level detected. By reading the colour change showing at a set time these alcohol testers give a guide to the actual blood alcohol level at the time of testing.

Breath testing is easy, cheap and reliable. All these alcohol testers are single use disposable test kits. Expiry dates are normally 24-36 months and storage is normally at room temperature with no special requirements. Two, ten second blows are needed to get an accurate reading. In donors with poor lung function, asthma, bronchitis etc this may render the test useless, so an option for these tests would be a saliva test strip alcohol tester.

Alcohol saliva testing is as simple and reliable as saliva drug testing, and indeed an ever increasing range of saliva drug tests do incorporate a saliva alcohol test strip with a 0.02%BAC sensitivity for workplace HSE screening.

The biotechnology is similar to the chemical breathalyser reaction with a colour change on a pad to which the saliva is added. The colour change is compared to a reference colour chart and the best match selected to give a semi quantitive alcohol level.

Both single use chemical breathalyser alcohol testers and saliva alcohol test strips are suitable for healthcare and workplace alcohol screening. Backed up with a digital breathalyser, these screens offer flexible, multi-location screening ability within a site or business. All test results are screening only, non evidential and all non negative results for alcohol should be confirmed using an accredited laboratory service offering evidential and chain of custody controlled certified results.

Saliva alcohol test kits are ideal for alcohol testing at work have introduced new lower pricing for saliva alcohol test kit products in 2011

The saliva alcohol test strip kit can also be used to detect alcohol in liquids and has widely been used by police and local authority alcohol street initiatives to combat under age drinking.

Currently priced at £22.99 per carton of 25 alcohol tests from Jan 2011 for a limited period only, the DAl-701 alcohol tests strips are available to buy online here with further bulk discounts available for 10 cartons and over. Purchase orders from Police authorities and councils can be e-mailed to

Alcohol test strip kit

DAL-701 is a professional standard alcohol test kit supplied in packs of 25 alcohol test strips or bulk 250 alcohol test packs.

The alcohol test is a professional In Vitro Medical Diagnostic test IVDD CE certified for professional alcohol detection in saliva. A simple saliva sample is taken and added to a reactive pad on the alcohol test strip. The colour change at 2 minutes indicates a semi quantative blood alcohol level at the time of sampling.

The alcohol test is also widely used to dip into other liquids as an instant test for alcohol. The result is not semi-quantative if the fluid tested is not saliva. Care must be taken to avoid liquids containing strong azo blue dyes, high caffeine levels and extreme pH products, but considering these limitations the test makes a very cost effective immediate point of test alcohol screen with the option of immediate saliva testing to evaluate blood alcohol levels if alcohol comsuption is suspected.

Alcohol test information

Government seek good practice approach to underage drinking

Every local authority is being sent a good practice guide to help them tackle underage drinking.

Policies involving police,trading standards, youth and childrens services have been developed.

Additional funding is also being targeted at youth crime action plan areas to fund police enforcement and detection, with many police forces and councils now being funded for the purchase of instant alcohol detection tests, simple dip tests which can be used to detect alcohol disguised in other liquids on the streets. Alcohol dip tests with IVDD saliva capability can also then test a saliva sample to indicate the actual blood alcohol concentration.

Alcohol Testing Strips-quick and easy way to check if under age drinkers are drinking alcohol

Alcohol testing strips are a quick and easy way to test if a fluid contains alcohol.

Designed originally to test saliva for the presence of alcohol, they can also be used to test any fluid for the presence of alcohol.

One particularly good use has been the testing of soft drinks for the presence of alcohol. Police forces across the country have been using alcohol test strips for this purpose now for several years, with excellent results. They can also be used at youth clubs, discos etc.

The alcohol test strips are individually foil wrapped and can easily be carried in a pocket. The strips are very simple & easy  to use . Simply dip the alcohol test strip into the liquid that is being tested and a pad on the strip changes colour if alcohol is present.
