Buy SELFCheck Multi Drug Test Online

SELFCheck's easy to use Multi Drug Test is a simple to use urine test which can produce visual results within 5 minutes.

The SELFCheck Multi Drug tests can detect 6 commonly abused drugs including:

  • Amphetamine
  • Benzodiazepines
  • Cannabis
  • Cocaine
  • Methamphetamine (including Ecstasy)
  • Opiates (including heroin)

When a person takes a drug in any form, the active substance is passed on to the bloodstream. Inhaled drugs enter the bloodstream via the lungs and ingested drugs (tablets, pills, syrups) enter the bloodstream during digestion. Injected drugs are injected directly into the bloodstream.

The bloodstream transports the drug to the parts of the body which utilise it. For instance, a drug might bind to receptors or cross the blood-brain barrier to act upon them. Once the drug has been used, the active substance and its metabolites are pushed back into the blood for expulsion.

The kidneys filter the blood and detoxify the body. They filter the blood, taking salts such as sodium and potassium and putting them back into the blood, and removing waste products used by your body, including drugs.

The SELFCheck Multi Drug test is sensitive to products in the urine which might indicate drug use.

Important: The SELFCheck drug test only provides a preliminary analytical result. It cannot determine the level of intoxication, how the drug was administered or how much of the drug is present.

Please read the accompanying leaflet before taking the test. Conducting the test wrong or contaminating the testing apparatus may result in a false result.

How SELFCheck Multi Drug Test works?

SELFCheck's Multi Drug test detects waste products in the urine which would indicate the use of drugs.

If a drug is present in the urine, a single line will show on the area marked "C". A negative result is marked by two lines.

Each result window represents a different drug.

Note: The test does not distinguish between abused drugs and certain medications. This means a positive result may occur in someone who is taking certain medications.

How do I use the test?

Before you begin the test, it's important to read the information in the provided leaflet.

Do not remove the cassette from the foil packaging until you are ready to take the test.

1.) Collect an adequate sample of urine to perform the test. About 2cm of urine is sufficient. Wait for the urine and foil pouch to reach room temperature before beginning the test.

2.) Carefully remove the test panel from the foil pouch and remove the protective cap from the bottom half of the device.

3.) With the protruding test strips pointing down, immerse the test panel into the urine up until, but not past, the black line. Keep the test panel submerged for 10 seconds.

4.) Lift the test panel from the urine sample carefully and place it on a flat, non-absorbent surface. You can use the packaging box or the foil pouch to rest the panel.

5.) Start counting up to 5 minutes. Your results will be visible at 5 minutes. Do not interpret results after 5 minutes. Results read after 5 minutes may not be accurate and may result in a false reading.

6.) Evaluate the results. A positive result will show only one line where it is marked "C". Two lines means the test result is negative. If one line appears for "T", the test is invalid and the result is inconclusive.

Note: If a feint line appears for "T", there is not a high enough concentration of that drug present in the urine to confirm a positive result. Therefore, a feint "T" line is still present.

Analysing the results

Important: You must interpret your test results at 5 minutes after removing the test strip from the sample. Interpreting your results before or after the 5-minute mark may result in incorrect readings.

For each drug the test detects, the result window can show a total of two lines - one marked with "C" for control line and one marked with "T" for Test line.

Regardless of whether the test is positive or negative, a control line should appear. If no control line appears, the test is invalid, regardless of whether there is a test line.

Positive result
A positive result means that the drug is present in the urine. This is shown as a single control line (marked with a "C") but no test line (marked with a "T").
Negative result
A negative result means the drug is not present in the urine. This is shown as two lines - one control line (marked with a "C") and one test line (marked with a "T").

SELFCheck Multi Drug Test technical information

The SELFCheck Multi Drug Test kit looks for specific classes of commonly abused drugs. Results of the test will depend on the concentration of the particular drug present in the urine. On top of the cut-off range of the test (which is the level of concentration of the drug needed to confirm whether a drug is present or not), there are other factors which may affect the test such as how long it takes for the drug to pass through the body.

Below is a table which details the drugs the test detects, the cut-off level and the detection times for each drug.

Drug (Identifier) Cut-off levels Minimum detection time Maximum detection time
Amphetamine (AMP) 1000ng/mL 2 to 7 hours 1 to 2 days
Benzodiazepines (BZO) 300ng/mL 2 to 7 hours 1 to 2 days
Cannabis (THC) 50ng/mL 2 hours Up to 5 days
Cocaine (COC) 300ng/mL 1 to 4 hours 2 to 4 days
Methamphetamine, inc Ecstasy (MET/mAMP) 1000ng/mL 2 to 7 hours 2 to 4 days
Opiates, inc Horoin (OPI) 2000ng/mL 2 hours 2 to 3 days


Note: The minimum and maximum detection time is a guideline and may be affected by an individuals' metabolism, excretion rates and general health.


Some medicines may interfere with the drug test and result in a false result, including:

  • Antibiotics
  • Antidepressants
  • Antihistamines (for allergies)
  • Antipsychotics
  • Efavirenz (for HIV)

If you are taking any of these, inform the person who is testing you.

If you are unsure whether any medication you are taking may interfere with a drug test, speak to your doctor.

The SELFCheck Multi Drug Test does not replace a drug test taken as part of the national drug screening programme.

Frequently asked questions

Why is it important to test for commonly abused drugs?

Abusing drugs can seriously impact an individuals' health and well-being. Some drugs can also affect people's alertness, which can put them in danger when driving or operating machinery. Identifying the use of drugs has a number of different benefits, including evaluating the safety or capacity of someone in the workplace, identifying whether someone may have or be at risk of developing a problem with addictive substances. Parents may wish you test their children for drug use during teenage years in order to get them the help they need and prevent them from becoming addicted to illicit substances.

How do these compare to lab based tests?

The SELFCheck Multi Drug Test is much faster and more convenient than traditional lab testing, while also providing accurate results. Unlike lab tests, which require a sample to be sent off to a laboratory, delaying the time you receive your results, the SELFCheck Multi Drug Test can give you results in just a few minutes.

Can I test multiple people?

No - the SELFCheck Multi Drug Test is a single use drug test which should only be used on one person.

For every person you need to test, a new test kit will need to be used.

Are the tests affected by alcohol or other medicines?

Alcohol and certain medicines may interfere with the test and cause incorrect results.

You may need to speak to the testee (the person who was tested) about the result. A second, more specialised drug test may be required to differentiate between a medicine and an abused drug.

Where can I buy a drug test?

You can buy a drug test online from Prescription Doctor today. The SELFCheck Multi Drug Test lets you check for the presence of commonly abused drugs in someone's blood stream at home.

How do I dispose of the used test?

Once the test has been used, you can discard of it in general household waste.

Be sure to wash your hands after disposing the used test.

Will pregnancy affect the result of the test?

The results of women who are pregnant or have recently given birth may cause false results.
