What are FYL Test Strips and How to Use them safely
FYL test strips are one of the most accessible and effective tools in the fight against accidental opioid overdoses. Designed to detect the presence of fentanyl—a powerful synthetic opioid often found in street drugs—these strips offer a quick and affordable way to test substances before use.
In this guide, we’ll break down what FYL test strips are, how they work, when to use them, and how to read the results. We’ll also answer the most common questions from individuals and organizations looking to add this tool to their harm reduction strategies.
🧪 What Are FYL Test Strips?
FYL stands for Fentanyl, and these test strips are thin, portable strips similar in appearance to a pregnancy test. They are designed to detect even trace amounts of fentanyl in a liquid solution derived from dissolving a sample of a drug.
Whether you’re a public health worker, harm reduction advocate, or simply someone looking out for your community, FYL test strips are a practical layer of protection.
🔍 How Do FYL Test Strips Work?
Using capillary technology, FYL test strips identify fentanyl and many of its analogs by reacting with the molecules in the sample. A visible line or two lines on the strip will indicate whether fentanyl is present.
Steps:
-
Dissolve a small amount of the substance in water (typically 10 mL).
-
Dip the FYL test strip into the solution for 15 seconds.
-
Lay the strip on a flat surface and wait about 2–5 minutes.
-
Read the results:
-
1 line = positive (fentanyl detected)
-
2 lines = negative (no fentanyl detected)
-
✅ Tip: Always use clean water and containers to avoid cross-contamination.
