What Is a 8-Panel Drug Test? Drugs Detected, Cost & Accuracy?
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026
Quick answer: A 8-panel drug test screens for the following drug classes — see the full list below with cutoffs.
Complete drug list
Standard configuration with typical urine immunoassay cutoffs:
| Drug class | Typical urine cutoff |
|---|---|
| 7-panel drugs | see above |
| Methadone or MDMA (config-dependent) | 300 ng/mL / 500 ng/mL |
Who uses this panel
Less common mid-size configuration; check which eighth drug your program orders.
What it does NOT catch
Blind spots: Varies with the eighth slot chosen. Absence from the strip means no testing occurs — specialty panels extend coverage when programs need it.
Cost & logistics
Cash-pay pricing for a 8-panel typically runs $30–$100 depending on lab network and turnaround. Results release in 1–2 business days for negatives; positives add confirmation and MRO review time. Home versions of most cup sizes sell for $15–$45 at pharmacies.

How accurate are drug tests?
Lab-based immunoassay screens agree with confirmation testing ~97% of the time; confirmed GC–MS results are considered definitive. Home kits trade legal defensibility for convenience.
Do prescriptions count against me?
No — verified prescriptions report as negative through the Medical Review Officer. Declare medications at collection and answer the follow-up call.
