Xylazine Test Strip

Questions?

• What is Xylazine Test Strip?

  Xylazine Test Strip is an immunoassay testing tool with antibodies sensitive enough to detect xylazine at concentrations over 10 ng/ml, sufficient to rule out dangerous amounts.

• What is included with Xylazine Test Strip?

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

• Are there any possible false positives?

  Yes, in two easy to avoid scenarios:

  1. It is required to dilute sample (100 mg / 200 ml) to avoid false positives with most stimulant drugs. Xylazine test strips are extremely sensitive, if you get a positive result repeat the test with 1/10th of the sample. If the result is then negative, it suggests a false positive could have occured before.
  2. Vitamine C can cause false positives – so we do not recommend testing cooker residue.

• How to use Xylazine Test Strip?

  

  METHOD 1   

  If testing a benzo/opioid 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.

  COMPARE RESULTS

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

• How to handle xylazine test strips?

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

• What types of tests are available?

  

• What is each reagent test for identification for?

  To compare reagents, check the table below. A ➕ sign indicates confirmation of the expected substance; at least two are recommended. A ➖ sign indicates exclusion of specific admixtures. A blank field indicates no use.

  

  • 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 cathinones, 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
    
    

  Reagents Mandelin and Scott have been discontinued and replaced by superior Morris reagent. 

  • Fentanyl Test Strip to detect fentanyl, even mixed in another substance.
  • Nitazene Test Strip to detect nitazenes, even mixed in another substance.
  • Xylazine Test Strip to detect xylazine, even mixed in another substance.
    
    

  Reagents for identification can indicate PRESENCE, but not QUANTITY. Mixtures can only be detected with reagents if the additive causes a darker color reaction than the expected substance. Test strips can detect PRESENCE in any sample. To detect all components and estimate their quantity, combine the test strips and identification reagents with a TLC purity test.
