Fentanyl Antibody Test Strip

• Fentanyl test strips are a harm reduction tool designed to provide important information about the possible presence of fentanyl in a sample. However, testing a sample with our products should not be considered a guarantee of safety. The consumption of any unregulated substance carries inherent risks.
• As with any rapid test method, these strips have technical and analytical limitations. No fentanyl test strip on the market can detect every fentanyl analog. Additionally, these strips cannot determine the presence of non-fentanyl synthetic opioids such as nitazenes or other emerging compounds. A negative result therefore does not guarantee that a sample is free from all synthetic opioids.
• False positives and false negatives are also possible. Variations in manufacturing batches, cross-reactivity with structurally similar compounds, improper dilution, or uneven distribution of fentanyl within a sample may influence results.
• Various external factors can also affect test performance and interpretation, including lighting conditions, sample preparation, and the presence of complex substance mixtures.
• Miraculix does not assume responsibility for the interpretation or use of test results. The use or misuse of this information and our products remains the responsibility of the end user.
• For increased safety, results should be interpreted within a broader harm reduction framework and, whenever possible, confirmed using advanced laboratory drug checking methods.

Is shipping discreet?

Yes. Your order is shipped in neutral, unbranded packaging with no indication of the contents. This ensures full privacy.  For more information, please see our shipping details.

How long does shipping take?

Shipping within the USA and Canada usually takes 1–4 business days. Orders are shipped Monday to Friday from our US distribution center. Delivery times for other countries may vary due to customs procedures.

What sample types can be tested?

This test can be used with powders, crystals, crushed pills/tablets, liquids, LSD blotters, and even residue (e.g. from bags or injection equipment). For solid samples like pills or crystals, always crush and mix thoroughly before testing. This helps ensure the sample is evenly distributed, as fentanyl may not be spread uniformly.

What drugs does it detect?

This test is designed specifically to detect fentanyl and many of its analogues.

What’s included in the test kit:

• Individually packaged fentanyl test strip
• 10 mg micro scoop
• QR code with full instructions

How long do results take?

Results are typically ready in about 3 minutes after dipping the strip.

How do I read the results?

• One line = positive (fentanyl detected)
• Two lines = negative (no fentanyl detected)
• No lines or invalid pattern = test is invalid and should be repeated

Always follow the full instructions, as incorrect dilution or timing can affect results. 

Can I reuse the test?

No. Each kit is single-use only.

Where can I learn more about substances and safe use?
