Detection timeframes vary for different drug tests and the kind of drug used. It is a very common question that is frequently requested by individuals, companies and other organization to understand detection timeframes for different tests. Some tests can go back as far as 90 days and even several months depending on the test selected.

Drug detection timeframes of detection

Depending on the type of test the detection of the drug in our system will vary. The following is a breakdown of drug detection timeframes for different ways a test is done, and the nature of the drug being tested.

Some additional factors that will influence the outcome of the drug test are:

  • The frequency of use of the drug
  • Type of Drug used
  • Body Mass
  • Quantity and strength of the drug used
  • Amount of hydration of the individual
  • Amount of exercise in the individual’s routine
  • The frequency of drug used
  • Gender of the person
  • The level of drug tolerance
  • Genetic makeup of the individual.

As you can see each person’s ability to assimilate and retain, a drug varies. Only a valid test will show the evidence on the drug’s presence in a person’s system. Trying to guess and using different methods to eliminate drugs from a person’s system, does not work efficiently. Traces of the drug remain in a person’s system. It also depends on timeframes of use and the kind of test conducted on the person.

Urine drug testing is one of the most common drug testing methods as it is quick, accurate and affordable. The other tests used as saliva, hair and blood. Different tests are used depending on the reason of the test. Testing can range from organization conducting mandated requirements, court orders, personal reason, child custody, probations and other requirements.

Hair drug test is used when there is a need to go beyond timeframes that Urine and saliva cannot provide. The retention period of drugs in hair is about 90 days for most drugs. It is accurate, there is very little room for error. The only drawback is the test is more expensive and has a longer turnaround time for results.

Drug Retention Period for different testing approaches:
