Blood tests are the least used for pre-employment drug screens because drugs are non-detectable in the blood stream after 48 hours. Labs generally report blood test results as quickly as they report urine test results.For most labs, that means results are available 24 hours after the specimen is tested, or 48 hours or more when the specimen must be delivered to a lab.hen drug screens return a negative result, the applicant is not tested again. The results of a negative test are usually available to employers within three business days after testing is completed. A positive test generally requires additional testing, and will thus take more time.
27th Jan 2014. This depends on which drug you are talking about, how much has been taken, how often it has been taken and what method is being used to test for the drug. The list below shows the number of days a urine drug test will continue to show positive after you have taken a drug. These times can differ depending on what testing kit is used, so this list is only a very general guide. For example, most tests for ecstasy will normally report positive for at least one day after the ecstasy was taken, but some tests will also report positive for up to 4 days after use. Further laboratory testing may be needed to exactly identify which drug has been taken. For example, further testing may be needed to confirm whether a positive result for opiates was due to heroin use or an over-the-counter headache medicine. â¢ Amphetamine 1-5 days â¢ Cannabis 2-3 days for one-off use (up to 2 months for chronic users)
