Fentanyl Test Strip is an immunoassay testing tool with antibodies sensitive enough to detect fentanyl and many derrivatives at concentrations over 10 ng/ml, sufficient to rule out dangerous amounts. Pairing fent strips with reagent testing is required to detect adulterants and increase analysis precision.

A positive or negative fentanyl test strip result does not indicate if a substance is safe. 
A sample that tested negative might still contain a lethal dose of fentanyl or other synthetic opioids. 
No substance is 100% safe

  • 1. Mix 100 mg of sample in 200 ml of tap water

  • 2. Dip no higher than thick line until liquid comes up (15 sec)

  • 3. Lay the strip flat, wait 3-5 minutes

  • 4. One top line = FENTANYL, Two lines (even faint) = NO FENTANYL

F.A.Q.

HOW SENSITIVE ARE FENTANYL TEST STRIPS?

Fentanyl Test Strips that we offer have been independently verified to be the best in detecting trace amounts of fentanyl:

  • 10 ng/ml – Fentanyl
  • 100 ng/ml – 3-Fluorofentanyl, 4-Fluorofentanyl, 4-Fluorobutyrfentanyl, 4-Fluorocyclopropylbenzylfentanyl, 4-Fluoroisobutyrfentanyl, Acetylfentanyl, Acrylfentanyl, Butyrfentanyl, Crotonylfentanyl, Cyclopropylfentanyl, Furanylbenzylfentanyl, Furanylfentanyl, Methoxyacetylfentanyl, Tetrahydrofuranylfentanyl
  • 250 ng/ml – Carfentanil (verified by Energy Control)
  • 1000 ng/ml – 3-Methylcrotonylfentanyl, 4-Chloroisobutyrfentanyl, cis-3-Methylfentanyl
  • Not measured – Benzoylfentanyl, Thiophenefentanyl (verified by PRO Test)

ARE THERE ANY POSSIBLE FALSE POSITIVES?

Yes, in two cases:

  1. You need to follow recommended sample dilution (100 mg / 200 ml) to avoid false positives with most stimulant drugs. Fentanyl test strips are extremely sensitive.
  2. Vitamin C causes false positives – so you can not test cooker residue. The tradeoff here is that PROTESTKIT fentanyl testers has been independently proven do detect the biggest number of fentanyl analogs.

HOW TO USE FENTANYL TEST STRIP?

METHOD 1   

If testing a pill, crush one in a plastic baggie and dump out the powder.  Then add 10 drops of water into the baggie and mix well. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.

METHOD 2

Mix 100 mg of sample in 200 ml of water. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.

To test weed for fentanyl (or any other herbal sample) proceed the same.

COMPARE RESULTS

1 line = fentanyl, 2 lines = no fentanyl. Faint lines also count. Ignore fentanyl tester results after 5 minutes.

HOW TO INTERPRET RESULTS?

Expected fentanyl test strip results:

  • Fentanyl – 1 line
  • No fentanyl – 2 lines (faint also count)
