General Questions
Which drug test is better, urine or saliva?
We recommend a urine drug test. Urine drug tests offer the widest combination of drug screens for the best value. They are also easier to perform correctly and provide a longer detection window after drug use.
I don't know what drugs I'm testing for?
If you are looking for a comprehensive drug screen, the Behemoth 17 Drug Urine Cup has been produced for this very purpose, to provide a comprehensive drug screen of the 17 most abused drugs.
Are the drug test results legally standing?
Our range of ALLTEST drug and alcohol screening tests need to be confirmed by a labratory urine or saliva drug test to be legally standing.
The lab drug test will be sent to a medical lab to confirm any non negative (positive) drug test results so that they can be used legally.
Is a drug test with 40ng or 500ng better?
Our inventory comprises a wide variety of drug tests, each designed to detect different substances at varying sensitivities.
Drug test sensitivity levels are typically expressed in nanograms, such as 20ng, signifying the test's ability to identify concentrations as low as 20ng/ml in urine or saliva samples.
As a general guideline, lower sensitivity values on a drug test indicate superior test performance, enabling the detection of even smaller concentrations of drugs or their metabolites, and extending the drug test detection window.
Additionally, products marked with the ⛛ symbol are part of our ultra-sensitive range of drug tests, representing our most advanced drug testing kits to date.
Urine Drug Test
Are all urine drug tests the same?
We offer three distinct types of urine drug tests, all operating on the same principle. The primary distinctions between these urine tests lies in the number of detectable drugs and user-friendliness.
Urine Drug Test Strip
The urine drug test strip represents the most economical option for screening for a single specific drug.
Urine Multi Drug Panel
When the need is to test for multiple drugs simultaneously, the urine multi-panel drug test emerges as a cost-effective and convenient drug testing solution by consolidating multiple test strips into a single drug test panel.
Urine Multi Drug Cup
The multi-drug test cup stands as our most high-end urine drug test, albeit pricier. This option presents the broadest range of drug combinations for detection and includes a user-friendly, sealable cup for sample collection. These attributes make it a top choice for workplace and home drug testing.
What can be detected in a urine test for drugs?
Nearly all drugs can be detected on an urine drug test, with the exception of anabolic steroids. If you require a drug test we don't have listed, you can try our wholesale website for a larger catalogue of drug testing kits and products https://www.ukdrugtesting.co.uk/
What are the detection windows for drugs in urine ?
As a general rule, most drugs are usually only detectable on a urine drug test, for up to 72 hours after last use, with the exception of Cannabis which can be detected for longer in some heavy users, even up to 30 days or longer in some cases.
More information on drug test detection times in urine can be found here.
What time of day I should carry out the urine drug test?
Morning would be the best time to perform a urine drug test. Drugs will generally be more concentrated in a first morning urine sample, than in a urine sample produced later in the day, after many drinks and beverages have been consumed.
Despite this a urine drug test can be performed accurately throughout the day.
What does a faint line on urine drug test result mean?
Negative Result: A faint line on most urine drug test kits, including the ALLTEST brand of drugs tests, indicates a negative result, meaning that the drug or its metabolites were not detected at or above the cutoff level of the drug test kit used. Even a faint line is a negative result on a drug test, as long as it is clearly visible, and it appeared with the specified time in the instructions.
Saliva Drug Test
Are all saliva drug tests the same?
There are two types of saliva drug test, direct and oral swab.
Oral drug tests include a separate saliva collector and oral swab or sponge. The swab or sponge must be wiped across the inside of the entire oral cavity to ensure enough saliva is collected and the drug test is valid.
Oral drug tests allow for larger drug panel combinations although can be harder to perform correctly.
We currently only sell oral drug tests. To see ouir full range of saliva drug testing kits visit UK Drug Testing.
What can be detected in a saliva test for drugs?
Nearly all drugs can be detected on a saliva drug test, however we have a smaller selection of drugs available for saliva detection, due to the tests being more complicated to perform.
If you require a drug test we don't have listed, visit our workplace drug testing kit website for a larger catalogue of drug testing products https://www.ukdrugtesting.co.uk/
What are the detection windows for drugs in saliva?
As a general rule, drugs are usually only detectable on a saliva drug test, for up to 48 hours after last use.
Cannabis and methadone have a very short detection period in the saliva of about 12-14 hours.
Detailed information on saliva drug test detection times and sensitivities
What time of day I should carry out the saliva drug test?
A saliva drug test can be performed at any time of day, but must be at least 20 minutes after the individual last ate, drank or smoked or put anything in their mouth.
What does a faint line on saliva drug test result mean?
Negative Result: A faint line on a saliva drug test indicates a negative result, meaning that the drug or its metabolites were not detected at or above the cutoff level of the saliva drug test kit used. Even a faint line can is a negative result as long as it is clearly visible, and it appeared with the specified time in the instructions.
An exception to this is the the Drugwipe drug test that is used by the UK police as their roadside drug test, where a faint line may mean a positive roadside drug test result.
