What are Fentanyl Test Strips?

SafeCheck Fentanyl test strips are a form of drug testing technology which can detect the presence of fentanyl in drug samples prior to use. Fentanyl Test Strips are a reliable, common-sense means of providing people at risk of fentanyl exposure with more information that can decrease risk of overdose. These test strips use the same easy-to-use technology that is found in pregnancy tests and recently COVID-19 tests. Included with each box is Fentanyl Test Strips along with a 10mg micro scoop, which is used for measuring precise sample sizes for accurate results.

How much sample is required for a test?

SafeCheck Fentanyl test strips require only a small amount of a substance in order to test, however we recommend testing an entire batch for the most accurate results. The test requires a minimum of 10-50 mg of substance, depending on the type of substance you are testing. Testing  a substance does not destroy or ruin it. After you have completed testing your batch, simply boil off the water used to dilute it.

How to use a SafeCheck Fentanyl Test Strip

All SafeCheck test kits come with instructions in the box. In addition, we provide QR codes with instructions for the sample collection method. Testing a substance for the presence of fentanyl requires only a few steps:

1. Dilute substance with water.

2. Dip the test strip into the solution for 15 seconds.

3. Wait 2-5 minutes and read the results.
