Frequently Asked Questions

Everything you need to know about the FYL Test Strip Kit with Hardshell Carry Case.

What’s IncludedTestingSafetyShipping & Warranty

What comes in the kit?

A hard-shell carry case, five WiseBatch FYL test strips, a mixing container, a 10 mg scoop, and instructions.

Does it include naloxone?

No. Add naloxone nasal spray to complete a full overdose prevention kit. The case is sized to hold 1 to 2 doses, and customers confirm their Narcan fits.

How big is the case?

It measures 6" L x 3.5" W x 2" H and fits in a bag or pocket.

How do I carry it?

It includes an optional carabiner, and it’s labeled “Overdose Prevention Kit” for fast identification. Customers say the bright red color makes it easy to find.

How do I use the test strips?

Add the substance with the 10 mg spoon to the mixing container filled with water and stir. Dip the test strip below the MAX line for 15 seconds, then wait about 5 minutes for the result.

How do I read the result?

One line means positive (“1 is hot”). Two lines means negative (“2 is not”).

How sensitive are the strips?

They detect FYL and 20+ analogs at 200 ng/mL, with a 98–99% accuracy rating in reproducibility testing. Every batch is lab-verified.

What can I test?

The strips are designed for powders, pills, liquids, and residue samples.

Is there a video guide?

Yes. A QR code on each pouch links to a step-by-step video, and you can download the FYL Test Strips Instructions Guide near the top of this page.

What do the results mean, and what don’t they tell me?

A positive result shows FYL is present, not how much.
A negative result doesn’t rule out FYL; it may be present below the test’s detection level.
Neither result means a substance is safe to use. The test doesn’t determine purity or composition, or detect other substances.
Technical or procedural errors and other substances can interfere with results.

The test is intended for harm reduction purposes only.

Do the test strips expire?

Yes. We can’t verify a test’s accuracy after its expiration date, and storage and procedure instructions must be followed for the most accurate result.

What should I do if a substance may contain FYL?

Treat it with extreme caution. Exposure to a small amount can cause serious health complications, respiratory depression, or death. Keep naloxone on hand and call 911 in an emergency.

Do you offer bulk pricing?

Yes. It’s sold as a single, 10 units, or 100 units. Select your quantity under Size.

10 units or fewer: fulfilled by Amazon, ships within 48 hours and arrives in 3 to 5 business days.

Quality kit

Everything arrived neatly packaged and organized. This is a high quality kit. This was purchased strictly for emergency situations. There is room in the kit to add narcan as well.

A MUST HAVE

I think this Fentanyl Test Strip Opioid Overdose Prevention Kit is incredibly well-designed and easy to use. It's small, manageable, tough, and easy to transport. This kit is perfect for Narcan nasal spray (although it doesn't include it – you can buy it at your local pharmacy!) It does come with testing strips. The case is strong, protective, and keeps everything organized, as well as easily accessible - the bright red color on it is eye catching/stands out too. Overall, I think this kit is very well-made, is of high-quality, and is designed very well- worth the price. An excellent and very necessary addition to my first-aid equipment. I'd recommend it.

Essential First Aid Kit Addition

Fentanyl Test Strip Opioid Overdose Prevention Kit - Reviewed January 2026.

I purchased this kit for emergency situations, and I'm incredibly impressed by its thoughtful design. The kit comes with everything you need, including high-quality testing strips. I love how everything is neatly packed and that each piece has a clear purpose, making the process straightforward even for first-time users. The kit is compact and lightweight, which is perfect for keeping it handy wherever you go. I use the case to store my Narcan nasal spray along with the test strips. The strong, protective case is well-made and the bright red color makes it easy to find. An excellent addition to my first aid supplies, I feel more prepared for emergencies with this kit by my side.

Although I haven't tested the strips' accuracy yet, they seem easy to use, and I see no reason to doubt their effectiveness. It's always safer to have naloxone on hand, and it's crucial to remember that it's not a substitute for emergency services – it's what you do while awaiting medical help. Despite being advised against storing naloxone in a car due to heat exposure, having this kit with me at all times gives me peace of mind, knowing I can potentially save a life.

helps

This kit is put together really thoughtfully. Everything comes neatly packed, and each piece has a clear purpose, so you’re not left guessing what goes where. The instructions are straightforward and easy to follow, which makes the whole process simple even if you’ve never used a kit like this before.

Easy to use and carry

This kit is well designed and sturdy, I particularly like that the case has room to add Naloxone to it. As noted in the description, you have to acquire the Naloxone separately, but that isn't difficult.

Overall I think this is a good kit for average people to carry if they're concerned about testing any unknown substances they come into contact with.
