Anabolic steroids Drug Test Guide: Panels, Detection Windows & More
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026
Quick answer: Anabolic-androgenic steroid hormones — not included on the federal 5-panel. Urine detects it roughly injectable/oral esters range ~2 days to 4+ weeks by compound (Dianabol ~3 days; Deca up to 18+ months in extreme cases per WADA literature); hair archives ~90 days; saliva and blood track only recent use. Sports/forensic LC–MS panels (T/E ratio, epitestosterone, designer esters); employment panels exclude them.
Overview
This guide covers everything verifiable about how testing handles Anabolic steroids (also searched as: testosterone, TRT, anabolic, Winstrol, Dianabol, Deca): which panels include it, detection windows across specimens, cutoff levels, false-positive risks, and legitimate prescription handling.
Panel membership
| Panel | Steroids status |
|---|---|
| 5-Panel | ❌ Not included |
| 10-Panel | ❌ Not included |
| 12-Panel | ❌ Not included |
| DOT 5-panel (safety-sensitive) | ❌ Not included |
Detection windows
| Test type | Typical Steroids detection window |
|---|---|
| Urine | oral_short: injectable/oral esters range ~2 days to 4+ weeks by compound (Dianabol ~3 days; Deca up to 18+ months in extreme cases per WADA literature) |
| Saliva (Mouth Swab) | any: rarely tested |
| Hair Follicles | experimental |
| Blood | any: compound-dependent |
Cutoff levels
Sports/forensic LC–MS panels (T/E ratio, epitestosterone, designer esters); employment panels exclude them.
Cutoffs exist to separate real use from noise — dietary exposure, passive contact and legacy medications stay below them by design. Screen-above-cutoff results still require mass-spec confirmation before reporting.
Deep-dive facts
Workplace drug panels DO NOT test for anabolic steroids — they require specialized sports-medicine mass-spec panels measuring testosterone metabolite ratios.
Anti-doping (WADA/NCAA/pro sports) uses those specialized panels with T:E ratio screening; employment HR testing simply doesn't.
Testosterone replacement therapy is invisible to standard employment cups; declare it in athletic testing contexts via TUE.
False positives & cross-reactivity
- Epitestosterone manipulations and designer steroids evade ratio screens; GC–C-IRMS isotope testing adjudicates elite sport cases.
| Screen flagged | Documented cross-reactants (immunoassay tier only) |
|---|---|
| Amphetamines | Bupropion (bupropion), trazodone, phentermine, pseudoephedrine, labetalol, promethazine, methylphenidate |
| PCP | Dextromethorphan (dextromethorphan cough syrup), diphenhydramine (diphenhydramine), doxylamine (multi-symptom cold remedies), tramadol, venlafaxine (venlafaxine), ketamine |
| Opiates | Poppy seeds (true positive), quinine, dextromethorphan, ofloxacin/levofloxacin, rifampin |
| Benzodiazepines | Sertraline (sertraline), oxaprozin (case reports) |
| Methadone | Diphenhydramine, doxylamine, verapamil, quetiapine (quetiapine), clomipramine |
| Tricyclics (TCA) | Cyclobenzaprine (cyclobenzaprine), hydroxyzine, carbamazepine, diphenhydramine |
| Cannabinoids (THC) | Efavirenz, pantoprazole (isolated reports); dronabinol/dronabinol = true positive |
Legal status note
Schedule III.

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.
