Anavar (oxandrolone) is an anabolic steroid that can cause a positive result on a drug test, depending on the type of screening used. Today, standard 5-panel and 10-panel urine tests do not typically include anabolic steroids, but specialized sports doping tests—such as those conducted by the World Anti-Doping Agency (WADA) or USADA—specifically target oxandrolone and its metabolites. If you are subject to athletic or employment screening that includes a steroid panel, Anavar can pop and remain detectable for weeks. This guide explains exactly what triggers a positive, how long Anavar stays in your system, and how drugpanels.com helps you verify your results with lab-grade accuracy.
How Anavar Is Detected in Drug Tests
Standard vs. Expanded Panels
Most workplace drug tests in the United States use a 5-panel or 10-panel urine screen that checks for marijuana, cocaine, opiates, amphetamines, and PCP. These panels do not test for anabolic steroids like Anavar. However, if an employer or sports organization orders a steroid panel (often part of a 12-panel or 14-panel test), oxandrolone will be detected via gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS).
Detection Windows for Anavar
The detection time for Anavar depends on dosage, frequency of use, metabolism, and hydration. Based on pharmacokinetic data:
- Urine test: 2–4 weeks after last dose (for chronic use)
- Blood test: 8–12 hours for parent drug; metabolites up to 3 days
- Hair test: Up to 90 days (rarely used for Anavar)
Because Anavar is an oral anabolic steroid with a half-life of about 9–10 hours, metabolites can linger in fatty tissues and be excreted slowly.
What Affects a Positive Result?
Test Sensitivity and Cutoff Levels
WADA-accredited labs use a cutoff of 5–10 ng/mL for oxandrolone. Even low doses (e.g., 10 mg/day) can exceed this threshold for weeks. The table below summarizes typical detection times by dosage:
| Daily Dose (mg) | Duration of Use | Urine Detection Window |
|---|---|---|
| 10–20 | 4 weeks | 10–14 days |
| 20–40 | 8 weeks | 14–21 days |
| 40–80 | 12 weeks | 21–28 days |
Note: Individual metabolism, liver function, and hydration can shift these windows by several days.
False Positives and Cross-Reactivity
Anavar does not cross-react with immunoassays for other steroids like testosterone or nandrolone. However, oxandrolone metabolites can trigger a positive on a GC-MS test if the lab uses a broad-spectrum screening. Some over-the-counter supplements contaminated with prohormones have caused false positives—always verify with a confirmatory test.
How to Test for Anavar at Home
At-Home Steroid Test Kits
Drugpanels.com offers urine-based dip cards and cassette tests that detect oxandrolone at a cutoff of 10 ng/mL. These are CLIA-waived and provide results in 5 minutes. For complete certainty, use a lab-based urine or hair test sent to a SAMHSA-certified facility.
Best Practices for Accurate Results
- Collect a first-morning urine sample for highest metabolite concentration.
- Avoid excessive water intake before testing (dilution can mask results).
- Store the test at room temperature (59–86°F).
- Read results within the manufacturer’s window (usually 5–10 minutes).

Frequently asked questions
Will Anavar show up on a standard 5-panel drug test?
No. Standard 5-panel tests do not screen for anabolic steroids like Anavar. You need a specialized steroid panel to detect oxandrolone.
How long does Anavar stay in your urine?
For chronic users, Anavar metabolites can be detected in urine for 2 to 4 weeks after the last dose, depending on dosage and metabolism.
Can Anavar cause a false positive for testosterone?
No. Anavar is a synthetic steroid (oxandrolone) and does not cross-react with testosterone immunoassays. False positives are rare but can occur from contaminated supplements.
What is the cutoff level for Anavar in a drug test?
WADA labs use a cutoff of 5–10 ng/mL for oxandrolone. Drugpanels.com home tests detect at 10 ng/mL.
