DESCRIPTION
The most sensitive, cost-effective, and accessible method for checking if your drugs contain fentanyl is by using Fentanyl Test Strips.
These strips were originally developed to test for fentanyl in urine, and have been found to work equally well for detecting fentanyl in any sample. The test strips that we sell here at DoseTest are the most reliable on the market.
The Fentanyl Test Strips are manufactured by BTNX, catalog number FYL-1S48-100.
WHY TEST
Whatever your choice of drug is, Fentanyl is more and more frequently popping up in samples such as Cocaine and Amphetamine, using these low-cost testing strips is the easiest way to ascertain whether or not your sample contains Fentanyl.
HOW TO USE
Solid samples
-
1: Mix your sample well. If you are testing a pressed tablet or pill, using a clean knife, break off a small part and crush it into a powder. If your substance is already in the form of a powder, mix it as thoroughly as possible.
2: Due to the sensitivity of fentanyl test strips, only a very small quantity (as much as a few grains of salt, ~5 mg) is needed. Place this amount into a cup, and add 5 mL (or 1 teaspoon) of tap water. As fentanyl is readily soluble in water, rigorous mixing is not needed.
3: Open the test strip package, and dip the test strip into the cup for 15 seconds, with the side that has the wavy lines pointing down. Do not submerge the strips over the wavy lines!
4: Remove the strip from the sample and set it horizontally on a clean surface. Wait 1-3 minutes before interpreting the result.
We recommend performing the test multiple times each time using a different part from your drug, to ensure there’s not a specific “hot-spot” with Fentanyl in.
Liquid samples
1: If preparing a shot for injection, first prepare the shot and fill your syringe. Then, with only the residue left over (1 drop or less), pour 5 mL (1 teaspoon) of tap water into the cup.
2: If your sample is in a bottle or vial, gently shake the container, and dispense one drop into a cup. Then add 5 mL (1 teaspoon) of tap water into the cup.
3: Open the test strip package, and dip the test strip into the cup for 15 seconds, with the side that has the wavy lines pointing down. Do not submerge the strips over the wavy lines!
4: Remove the strip from the sample and set it horizontally on a clean surface. Wait 1-3 minutes before interpreting the result.
Testing Scenarios
Methamphetamine and MDMA are two drugs that can cause false positives with fentanyl test strips. When testing these substances it is important to make sure your dilution is about 1 mg/mL. Using the above protocols, false positives should be minimized, however if you are testing one of these substances and obtain a positive result, it is recommended to increase your dilution and test again with a new test strip. If the second test is also positive for fentanyl, it should be assumed that fentanyl is present in your sample.
Other substances that may cause false positives:
Isopropylphenidate or IPPH
Diphenhydramine
Different results for the same sample
If two different results are read for the same sample, repeat the test again. As such a small amount of the sample is tested, and as solid samples such as pressed pills or powders might not be homogenous, it is possible that fentanyl may be present in your sample only in one area of the pill or baggie. This is why it is best to test more than one area of a pill or of a powder and to mix your sample as much as possible before testing! It may be wise to test a larger quantity of your substance, which will allow for a more accurate representation of your sample. To do this you would dissolve 15 mg of your sample (0.015 g) in 15 mL (1 tablespoon) of tap water. Keep a ratio of 1 mg sample to 1 mL water to reach the optimal zone well above the detection limit of the strips and below the area where other compounds in the sample could produce a false result.
Faint second line
Sometimes after dipping the strip in the test solution a faint second line appears, leading to confusion when interpreting the result. Most harm reduction organizations assert that any second line, no matter how faint, should be interpreted as negative (3). For the minimization of risk, we recommend re-testing your sample with a new test strip if you are unsure of how to interpret the result.
Control line does not show up
If the control line, which is the top line when the strip is held with the wavy side at the bottom, does not appear, it means the fentanyl test strip is defective and should be discarded. Test again using a new strip.
