How long before the Pre-Employment Drug Testing Result will be Release?

Waiting for pre-employment drug testing results can be tiresome for employers and applicant alike especially if the company needs to hire the applicant immediately because of the higher demand for the position. Various factors identify how long an employer will have to wait for results, including what type of drugs are tested and whether the applicant is taking a prescribed medicine that might highly affect the outcome of the test. By knowing what to assume, you can better prepare for the result of a pre-employment drug testing.

Following a preliminary positive test, the lab will perform a second test to rule out a false positive. The second test is conducted using gas chromatography and mass spectrometry. These procedures will remove error and give the tester with details about the amount of a substance present in the specimen. It may take 4-5 days before results of a positive test are made available to the employer.The wait time for drug screen results depends on which drugs are tested. Commonly, employers follow the Substance Abuse and Mental Health Services Administration standardized regulations. Here are the types of pre-employment drug testing and the waiting time for the results:

  • timeUrine Testing – Urine is the most commonly specimen used for drug testing. For the reason that it provides the fastest turnaround time of all types of drug screens. Most medical laboratories can process a drug screen in one to two business days. On the other hand, if the specimens must be send to the testing facility from the lab, this may add more business day. For negative urine screens, results are normally available to the employer by the third business day. For positive test, the results are obtainable after four or five business days.
  •  Hair Testing – Hair testing can identify drug use up to 90 days prior the date of the test. The downside to hair testing is that results take more time than urine testing. Based on the diagnostics testing companies, results of hair drug screens typically take five to ten business days to deliver.
  • Blood Testing – Blood tests are the least practiced for pre-employment drug testing because drugs are non-visible in the blood stream after 48 hours. Results are available 24 hours after the specimen is screened, or 48 hours or more when the specimen must be send to a lab.
