Urine drug testing

Urine drug testing looks for short historic drug use as well as current drug use. Consequently a urine drug test does not screen for intoxication or prove that a drug is currently in the donors' blood at a level to cause a psychoactive effect.

A non-negative urine drug test result indicates drug use within the guide window for detection given for each drug group included in the drug testing kit that was used.

Are there any drawbacks to urine drug testing?

  • The main drawback to urine drug testing, is that it is harder to be sure that the urine sample has not been tampered with in any way or does, in fact, belong to the person that you are drug testing.
  • Urine specimens for both screening on-site drug tests and legally defensible back-to-lab drug testing need to be collected under circumstances which respect the dignity of the individual whilst ensuring that the urine specimen is freshly voided so you need to make sure that you provide this.

Three things that you can do to ensure that the urine sample that you are provided with for the drug test is genuine and has not been tampered with: 

  • Put a blue dye block into the toilet cistern, so that if water from the toilet bowl is added or substituted, it will be very obvious.
  • Use a drug test kit or cup with a temperature strip to check that the urine sample is body temperature & fresh. 
  • You can also use urine adulteration test strips to check that the sample has not been diluted and is in fact urine. Some drug test cups have these built in.

Which are the best urine drug test kits?

  • Most drug testing companies sell a confusing array of choices.
  • There is no official guidance in the UK on what to include in the drug tests you choose.
