• What is a Fentanyl Test Strip?

  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.

  Reagent tests and test strips can indicate PRESENCE, but not PURITY or QUANTITY. Mixtures can be detected with reagents only in case of fentanyl test strips or if adulterant causes a darker reagent test color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.

• 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 / 100 ml) to avoid false positives with most stimulant drugs. Fentanyl test strips are extremely sensitive, if you got a positive result repeat the test with 1/10th of used sample size. If result is negative that suggests a false positive occured.
  2. Vitamine C causes false positives – so you can not test cooker residue.
• What is included with Fentanyl Test Strip?

  The Fentanyl Test Strip comes in a hermetically sealed disposable pouch with silica gel packet inside.

• What is each kind of test for?

  To compare tests see the chart below. ➕➕ = positively indicates presence of expected substance. At least 2 are recommended to reduce the risk of inconclusive result. ➕ = positively indicates presence of some adulterants (see footnotes). ➖ = not applicable.

  • Cannabis (4-AP) – main test for THC / CBD, helps rule out synthetic cannabinoids
  • Ehrlich – main test for all indoles, e.g. lysergamides and tryptamines but also 5-HTP and more, secondary test for cocaine
  • Hofmann – main test for lysergamides and tryptamines, more precise but slower than Ehrlich
  • Froehde – main test for most powders, secondary test for ketamine and amphetamines, long shelf life
  • Liebermann – main test for most powders, secondary test for cocaine (detects levamisole)
  • Marquis – main test for most powders, secondary test for ketamine, mephedrone and psychedelics
  • Mecke – main test for most powders, secondary test for cocaine, ketamine and mephedrone
  • Morris – main test for cocaine and ketamine, can tell apart some novel dissociatives
  • Robadope – main test for primary amines, e.g. MDA, amphetamine or PMA
  • Simon – main test for secondary amines, e.g. MDMA, meth, mephedrone, methylone or PMMA
  • Zimmermann / Beam – main test for cathinones and benzodiazepines in geneal, detects also CBD

  Fentanyl Test Strip to detect fentanyl, even if it is mixed in another substance.

  Reagents can indicate PRESENCE, but not PURITY or QUANTITY. Adulterants can be detected with reagents only if they cause a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.

• How to use a 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

  Dissolve 100 mg of sample in 100 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. 

  COMPARE RESULTS

  1 line = fentanyl, 2 lines = no fentanyl. Faint lines also count. 

  To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.

• How to interpret results?

  Expected fentanyl test strip results:

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

• How to handle fentanyl test strips?

  Do not freeze test strips. Use before the date printed on the packaging.

• How to test purity, not just presence?

  Pair reagents with a TLC purity test kit. TLC allows you to discover full number of ingredients and estimate their amount, however still requires reagent tests to identify detected compounds.

  • To precisely test MDMA purity use TLC MDMA Purity Test Kit.
  • To precisely test cocaine purity use TLC Cocaine Purity Test Kit.
  • To precisely test cannabinoids use TLC Cannabinoid Test Kit.
  • To estimate purity of other compounds (full ingredients and their amounts) use the basic TLC Adulterants Test Kit.
  • To precisely test purity of as many compounds as possible consider the Full TLC Purity Test Kit.
