Drug tests

Accurate testing to detect whether or not you have taken drugs.

Drug abuse is a pattern of using drugs that can cause serious problems at work, in your relationships, and general health. Drug use tests are often requested by physicians or drug abuse counsellors, in order to fully understand a patient’s symptoms, drug use, and medication history. 

A drugs of abuse screen is done using blood or urine samples, and will show the presence and quantity of specific drugs in the body. Some tests can also show if you are at low, moderate, or high risk for complications from drug abuse.

Drug abuse may also be called drug addiction or substance abuse. Substance abuse can also refer to the abuse of other substances including alcohol and inhalants. Inhalants are household products, such as paint thinner and certain types of glue, that contain substances that affect perception and mood when inhaled.

Which drugs are being tested for?

A drugs of abuse test detects the presence of various classes of abused drugs. The initial analysis is a screening test for broad groups of drugs (e.g. opiates – heroin, morphine, codeine etc) is detected; positive results are then followed up by a more specific test which identifies the individual drug taken (e.g. morphine).

A drugs of abuse ‘screen’ usually comprises the more commonly abused drug groups, which are the opiates, benzodiazepines, barbiturates, cannabinoids, amphetamines (including Ecstasy) and cocaine. Drugs used in the treatment of opiate addiction (methadone and buprenorphine) and ‘legal highs’ are also often detected.

Before the test

You will need to hold your urine for 2 hours before your appointment, in order to provide the best sample for testing.

During the test

A urine sample will be taken at the clinic. The doctor will explain to you what to do.
