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.
Quick Answer. The results from a urine test can take from a few days to a week for a positive screen, while negative results are usually found in a single day. Additionally, if a rapid test is requested, the results are received on the same day. Some drugs are detectable in urine from a couple days to three or four weeks with chronic use, such as marijuana. To reduce the chances of a false-positive, provide an up-to-date history of all prescription, over-the-counter and herbal drug use prior to taking the urine test. If a positive result is received, some labs have the option to pay for a retest of the original urine sample.
