Urine drug testing explained
- 1 When a person consumes drugs, they are broken down by the liver, and a proportion of the drug and its metabolites are released into the bloodstream, while some of the drug is excreted from the body in a variety of ways, including in urine.
- 2 The test works by analysing a urine sample for the presence of drugs and their metabolites.
- 3 Urine drug testing provides what is known as a ‘narrow-window’ detection period of up to 4 days after drugs were consumed.
- 4 Urine drug testing can be used effectively to complement hair or nail drug testing (both of which provide an insight into historic drug use) to give a much more detailed, accurate picture of an individual’s long-term and short-term drug use.
- Urine drug testing is ideal for regular use during childcare pre-proceedings. For example, where a parent has sole custody of the child(ren) over a weekend or after planned child visitation.
- It is also useful for Family Drug and Alcohol Courts (FDACs), where regular, repeat drug testing is required.

Sample collection
- Urine samples for legally-instructed drug tests can only be collected at our walk-in centres across the UK and Ireland. Sample collection is FREE at our walk-in centres for all legally-instructed tests.
- The sample donor will be asked to provide a urine sample using a fully self-contained urine screening kit that detects the presence of certain drugs in a donor’s urine sample.
- Prior to sample collection, our trained sample collectors prepare a suitable toilet and washing facilities for the donor to use when collecting their sample. This preparation includes a number of careful measures to reduce the possibility of sample tampering.
- The donor will then collect their urine sample in private.
- The sample collector will look at the test strips on the side of the pot. For a negative result, coloured lines will appear on the test strips indicating that none of the substances were detected.
- For a non-negative result, no coloured lines will appear on the test strips for the corresponding drug. This indicates that the substance has been detected.
- For non-negative samples, the sample collector will transfer the urine sample in equal quantities into two separate containers, representing an A and a B sample. These samples are then safely transported back to our toxicology laboratory for in-depth analysis, and confirmation of the results.
-
We also offer back-to-lab urine drug testing. For this test, there is no instant screening. Instead, our sample collector will collect a urine sample from the donor at one of our walk-in centres. The sample is then returned to our laboratory for testing.
