The visit itself is quick — verify ID, complete chain-of-custody paperwork, provide the sample. Most candidates are in and out within 20 minutes. Negative results are usually reported to the employer within 1–2 business days. A non-negative screen goes to confirmatory GC-MS testing and Medical Review Officer evaluation (to account for legitimate prescriptions), which adds 2–4 days.
How long does a pre-employment drug test take?
Quick answer:
The collection takes 10–15 minutes. Negative results typically return within 24–48 hours; non-negative results take longer due to confirmation testing and MRO review.
