  • easiness and non-invasiveness in the sample collection
  • it is not necessary to use special toilet facilities
  • the collection of the sample by personnel of the same sex of the patient is not necessary
  • it is difficult to adulterate the sample
  • the risk of infection for those who collect the sample is certainly lower than blood
  • the fluid better reflects the recent use of drugs
