How do I interpret a result on a drug testing kit

NEGATIVE: A coloured line appears in the Control region (C) and coloured lines appear in the Test region (T). This negative result means that the concentrations in the urine sample are below the designated cut-off levels for a particular drug tested.
*NOTE: The shade of the colored lines(s) in the Test region (T) may vary. The result should be considered negative whenever there is even a faint line.
POSITIVE:A coloured line appears in the Control region (C) and NO line appears in the Test region (T). The positive result means that the drug concentration in the urine sample is greater than the designated cut-off for a specific drug.
INVALID: No line appears in the Control region (C). Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for Control line failure. Read the directions again and repeat the drug test with a new test kit. If the result is still invalid, contact your supplier.

What is the Control line C
A procedural control is included in the every near patient drug testing kit. A coloured line appearing in the control region (C) is considered an internal procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique.

How long do drugs stay positive on a drug test ?

The amount of time drugs stay in the body depends on many factors such as, the amount of the drug taken, its strength, purity, the body weight of the person being tested and rate of metabolism, and whether they are a casual user or a long term user.

Cut offs for onsite drug testing kits are brand specific and as a guide the window period for drug detection using saliva or oral fluid drug test are shorter than comparable urine drug test.

As a rough guideline most drugs (excluding cannabis will be detectable on a urine drug test for up to 3-4 days) and on a saliva drug test for up to a maximum of 72 hours (some saliva tests are only up to 24 hours)

Cannabis can be detected in some individuals on a urine drug test for up to 28-30 days (depends on individual useage and body fat composition as Cannabis metabolites stored in body fat)

Detection times in hair drug tests are longer

Why does cannabis stay in the body for longer?

Cannabis is fat soluble, so over sustained regular use it is deposited around the body and can take several weeks, to a month to be excreted in some individuals. In practice this only occurs in heavy regular consumers of cannabis, usually the concentrated forms such as skunk, and for most irreglular or occassioanl users THC will be excreted much more quickly

There is a faint line on the drug test-is this still a negative test ?

There is a faint line on the drug test-is this still a negative test ?

This is a common question and one that can cause a lot of worry & confusion. Two lines on a urine or saliva drug test kit that appear within the specified test time is a negative result. It does not matter if the test line is faint when compared to the control line.

The picture on the left shows a very clear negative result on a single urine drug test kit where both lines are of equal intensity. However sometimes the two lines may differ in intensity, and this is still a negative result. This is not of any significance and should be ignored. The test result is negative whether the line is faint or dark.

How accurate are the drug tests ?

The onsite urine and saliva drug testing kits that we supply are between 97-99% accurate if used according to the manufacturers instructions.

Can the drug testing kits be used in an industrial tribunal ?

The onsite drug testing kits that we supply are drug screening tests and are not suitable for use alone in an industrial tribunal. If a positive is detected on the onsite drug test then a urine sample should be sent to a laboratory for confirmation drug testing by GCMS.
Full chain of custody procedure must be followed if the result is to be used for an industrial tribunal.

Which breath alcohol detector should we choose to test a professional driver ?

'We want to test our fork lift drivers randomly for alcohol. We are looking at the disposable breath alcohol detectors. Can you please advise which sensitivity we should go for.'

Answer
Because a fork lift driver is a professional driver and is operating machinery in a workplace, then you need to go for the 0.02% or zero tolerance breath alcohol detectors.

I am doing workplace drug testing-what do I do if the instant test is positive ?

All positive onsite drug test results will need to be confirmed using an accredited laboratory procedure. Usually this is by GC/MS (gas chromatography, mass spectrometry) which determines the exact drug and amount in the sample. This should be completed before any employment consequence is applied but the employee may be removed from the workplace on full pay, pending the confirmation test result if the employer considers there may be a risk to them or other workers.

Can you buy home drug testing kits from a chemist ?

Currently in the UK there are a small number of chemists & pharmacies that do stock home drug testing kits. This number is likely to increase over the coming months and years. It is likely that they will be available initially in big cities such as London, Liverpool, & Glasgow and that the choice will be fairly limited as to which drugs you can test for. We may get to the situation a a few years where they are as widely available as other home test kits such as pregnancy tests.

Does a negative drug test mean that no drugs have been consumed ?

A negative result may not necessarily indicate a drug free specimen. Drugs may be present in the urine or saliva specimen below the cut off level of the drug testing kit that was used. If you are still suspicious that drugs have been consumed, despite a negative instant drug test result then a Laboratory GCMS drug test should be performed on the specimen

Does the drug testing kit indicate the quantity of drugs consumed ?

A positive result on a urine or saliva drug test kit does not indicate the concentration of drug in the specimen or the route of administration. To get the concentration of drugs in the sample a Lab GCMS drug test would need to be perfomed.

What does a faint line on a drug test mean ?

What does a faint line on a drug test mean ?

This is a common question. On this picture you can see two drug test results. Both drug tests were performed on the same sample of urine at the same time. The one on the left was done using a cassette drug test kit and the one on the right using a drug test strip. Both the test membranes are to the same sensitivity and cut off levels, and both of these results are negative ie no drug was detected. The T line on the test strip on the right of the photo is very faint in this case, but this is still a negative result. The faintness of the test line is of no significance and should not be interpreted in any other way than as a negative result.

Do you sell the drug testing kits that show what levels of drugs are still in a person's system?

The drug testing kits will not tell you the level of drugs detected by the test. They will just give you a positive ( drug detected above the cut off level of the test ) or a negative ( drug not detected above the cutoff level of the test) result. The detection levl of the test varies depending on which drug is being tested for. The levels are set above zero to avoid false positives caused by accidently coming into contact with a drug, through passive inhaltion or low level contamination.
A laboratory drug test will tell you the level of drugs detected.

Can you please let me know what the shelf life for the drug testing kit is ?

The shelf life is the date by which the test should be used. It is similar to the dates on food in the supermarket. Most drug test kits are manufactured with a 24 month shelf life. Uirne drug test kits tend to have a longer shelf life than saliva drug test kits at manufacture. Urine is usually 24 months and saliva 18 months from manufacture. By the time they reach us they usually have about 18-23 months expiry date on them. All the drug testing kits that we sell will have at least 12 months shelf life on them ( excludes special offers where drug tests may be reduced because of short shelf life ) The most popular ones, such as the workplace drug testing kits that sell very quickly, will usually have the longest shelf life.
If you would like to know the shelf life for a particular drug testing kit in stock then please contact us.

Can schools drug test their students in the UK?

The simple answer is yes. Currently most drug testing that is done in UK schools is following an incident where there is suspicion of drug use in a particular pupil or group of pupils. To perform the drug test the school will need to have both the pupils and the parents consent. Drug testing is currently more prevalent in private schools in the UK than in state schools.

If the pupil is going to be disciplined or possibly expelled based on the result of the drug test then full chain of custody with witness to the drug test should be adhered to , with a laboratory confirmation drug test to confirm any positive results. If the drug testing is being done with a view to helping the pupil, without disciplianary procedure, then a screening test is all that will be needed initially.
