How long does a drug test stay positive ?

The length of time a drug test stays positive depends on:
• the drug that has been used
• the type of drug test kit being used ie whether it is a urine drug test, a saliva drug test or a hair drug test. As a general rule a urine test will stay positive longer than a saliva drug test.
• the sensitivity of the drug test being used
• the metabolism of the person being tested-some individuals clear drugs out of their system faster than others
• the frequency and strength of the drugs used

How long does Cannabis stay positive on a urine drug test ?

Why does Cannabis stay positive on a drug test for so long ?

Cannabis can stay in the body for longer than other drugs because it is stored in fat. If someone is a heavy frequent user then the THC ( Cannabis ) can be stored in their fat cells for up to 28-30 days in some cases. Therefore whether or not a Cannabis drug test stays positive, and for how long it stays positve varies from person to person, depending on the individuals body type & metabolism. In some cases it can be out of the system and clear on a urine drug test in about 4-5 days, and in others it may take up to a month to clear from the urine drug test.Cannabis THC drug testing kits
Is a faint test line on the drug testing kit still a negative ?

Is a faint test line on the drug testing kit still a negative ?

Two lines ( a control line and a test line ) 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 right shows a very clear negative result on a urine drug test 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. Drug Testing Kits

What do the codes on the drug tests mean ?

Below are the coding abbrevaitions as they appear on the packaging and on the drug testing kits, and a definition of what they actually test for:

How much urine do you need for a urine drug test ?

For a multi-panel urine drug test or an E-Z cup drug test you will need between 20-80ml of urine to perform the test. If you are using a simple urine dipstick drug test that tests for just one drug you will need about 20-30ml. You may be able to perform the test on a smaller sample, if you are just using a single strip test.

Is there a drug testing kit for MCAT mephedrone ?

There is now an onsite drug testing kit manufactured that detects MCAT specifically, also known as meow meow, bubble or mephedrone. These drug test kits are now available as a single urine drug testing kit only, but will soon be incorporated into the multi panel, and urine drug testing cup tests.

Because street drugs are often cut with other compounds such as amphetamine and methamphetamine, then an instant drug test for these may show positive in some cases although it is not actually the MCAT that is being detected. MCAT can aslo be detected by laboratory tests on urine, saliva & hair so if the sample is sent to a mephedrone may be detected.

Which drug test kits are the best ?

Another very common question, that we are asked frequently by businesses, who want to make sure they purchase the best drug testing kits. The answer depends on the context in which the test is being used. For most businesses a saliva drug testing kit is the best choice, as this allows them to be sure that the sample has come from the indivual being tested. The drug test is simple to administer and gives immediate results. The down side is that you do not have a urine sample for laboratory confirmation, so many employers will confirm a positve saliva test with a urine drug test.

If you need any advice on choosing which is the best drug test kit for your particular situation contact our experienced customer services team who will be happy to advise you.

Are drug testing kits available to buy on the high street in UK ?

Currently drug testing kits are not widely available on the UK high street, and most are sold online over the internet. They are available in a small number of limited independent pharmacies across the UK, mainly in large cities such as Liverpool, Glasgow and London.

It is likely that over the next few years we will see home drug test kits become more widely available, until they become available in high street pharmacies such as Boots and Lloyds, in a similar way that pregnancy tests are now widely available and in the longer run they are likely to be sold in supermarkets.

Which are the best drug testing kits for employee drug testing ?

Many employers find that saliva drug testing kits are more convenient for first line drug screening than urine, as there is no need for urine collection or handling, collection can be easily observed, and can be perfomed easily onsite anywhere, without the need for toilet facilities. The results are available immediately within about 5-10 minutes, and there are fewer chain of custody implications, as the sampling can be directly observed.

Another advantage to saliva drug testing for employers is that the window of detection for saliva is generally much shorter than with urine, and so a positive result suggests that an employee is under the influence of drugs, while at work. Posive results on onsite tests should be confirmed with a laboratory urine drug test.

If toilet facillities are available, then urine drug testing may be an option. The advantage of urine drug testing is that it is generally much cheaper then saliva testing, is very easy to perfom and in the case of the E-Z drug test kits with incorporated cup, the sample can easily be sent to a lab for confirmation if positive.

Ketamine is becomingly increasingly popular in the UK, and is now available as a screen on several multi panel urine drug testing kits, as well as available as a single urine drug test kit. We do not currently have an onsite rapid saliva drug testing kit for Ketamine but a laboratory test would be able to detect it.

Can you ask an employee to take a drug test ?

Because of the health & safety risks associated with the use of drugs in the workplace it is important to have a drug testing policy written in to your company contract, and also into your health and safety policy. This should be drawn up between employer and employees. In the policy you should assess any health risks associated with drug misuse within the workplace, any health and safety benefits that drug testing will give, how & when the testing will be done, and what disciplinary action will be taken. To drug test your employees you need their consent.

Where can you get a drug test done ?

Many companies now do their own onsite drug testing. To do this you can either have an allocated member of staff to do the testing, or you can use a drug testing company to come in and provide the service. We can supply you with drug testing kits to do the testing yourselves, or we can refer you on to companies that we work with, who will come in and do the testing for you.

Alternatively you may consider using an occupational healthcare provider. In this case the person being drug tested will usually go to the office of the provider, and the drug test will be performed there. Some GP surgeries will povide this service as part of an employment or pre-employment medical, although you may need to provide the drug testing kit.

If you are recruiting, many recruitment agencies provide drug testing as part of the pre-employment screening process.

Do the Opiate drug test membranes detect Fentanyl ?

Fentanyl is a seperate drug test membrane to Opiates and there is no cross reactivity. We do not currently have any Fentanyl membranes in our UK stock but if you require drug test kits with a Fentanyl membrane we can have them manufactured for you. Contact us for pricing.

Do you have a drug testing kit to detect U-47700 ?

U47700 is a synthetic drug with an opiod effect. It is said to have a much stronger effect than heroin and has been connected with a large number of deaths in the USA and some in Europe mainly thought to be due to respiratory depression. The drug which is a painkiller can be taken orally, injected or snorted. We do not currently have a drug testing kit to detect this drug.

What is APB and how do we screen for it?

As drug users realise that employers and the police roadside test are screening for Cannabis, new synthetic forms of Cannabis such as APB and K2, that are not detected on a standard THC test, are becoming more popular and widely abused.
Many of our newer workplace drug testing kirts now include a screen for K2.
