10-Panel Drug Test (Urine Screen)

On TestWell the 10-panel urine drug screen is $149.99 (plus a $6 lab processing fee), collected at a Labcorp patient service center, and the price includes mass-spectrometry confirmation of any positive — the step that turns a screen into a defensible result. Quest Health lists a comparable confirmed panel at about $249. Screen-only 10-panels without confirmation are cheaper (commonly $50–$100 at urgent-care and testing centers), but a positive then costs $50–$150 per drug class to confirm; instant cup tests bought at pharmacies are $20–$40 and are not confirmed at all.

THC (marijuana), cocaine, opiates (morphine, codeine, heroin metabolite), amphetamines (including methamphetamine), PCP, barbiturates, benzodiazepines, methadone, oxycodone and propoxyphene. Alcohol, fentanyl, tramadol and synthetic cannabinoids are not on a standard 10-panel; they need separate tests.

Approximate windows for a standard cutoff: cocaine 2–4 days; opiates and oxycodone 2–4 days; amphetamines 2–4 days; PCP 7–14 days; methadone 3–7 days; benzodiazepines 3–7 days (weeks for long-acting ones taken regularly); barbiturates 2–7 days (short-acting) to several weeks (phenobarbital); THC 3 days after a single use, 1–2 weeks with regular use, and 30 days or more with daily heavy use. Hydration, body fat and metabolism shift these ranges.

Usually not directly. Employment and legal drug tests generally require chain-of-custody collection — observed or documented specimen handling at a site the employer or court designates — and DOT tests follow their own federal panel. TestWell's test is a clinical screen ordered by a physician with results delivered to you, which is what you want for personal verification or medical monitoring. If you need a chain-of-custody result, ask the requesting party where to be collected.

Negative screens are usually reported in 1–2 business days. A presumptive positive is automatically sent for LC-MS/MS or GC-MS confirmation, which adds 1–3 business days, so a confirmed result typically posts within 3–5 days. Only confirmed positives are reported as positive.

Usually, yes. Most pre-employment and workplace programs order a 5-, 10- or 12-panel urine screen, and the 10-panel is the common standard. Check the employer's or court's paperwork for two things before you order: whether they require a chain-of-custody collection (an observed, sealed specimen with documentation) and whether they name a specific panel. This test is a standard lab collection at a Labcorp patient service center with laboratory confirmation of any presumptive positive; it is not a DOT-regulated collection.

At any Labcorp patient service center — order online, a licensed physician authorizes the requisition, and you walk in for the urine collection; the ZIP finder on this page shows the nearest locations and hours. Results post to your portal in 1–3 business days (longer if a presumptive positive goes to confirmation).

No fasting. Don't over-hydrate before the collection — a very dilute sample (low creatinine and specific gravity) is flagged and may need to be repeated. Bring a list of prescription and over-the-counter medications; the confirming physician uses it to interpret expected positives such as a prescribed benzodiazepine or oxycodone.

No, fasting is not required for a 10-Panel Drug Screen (Urine) — you can eat normally and book any time of day. Avoid excessive fluid intake before collection, as overly dilute samples may require a retest.

The 10-Panel Drug Screen (Urine) is Labcorp test number 912081 ("Drug Screen 17 w/Conf, UR"). TestWell orders it under that code for $149.99 at Labcorp — no doctor's visit or insurance required, results in 1–3 business days. Codes verified against the labs' catalogs in 2026.
