## Questions & Answers

**Q: What is extraction liquid and why can’t I just use regular bottled water to dissolve the powder I’m testing?**
A: Hi there, here is what is in the buffer solution:

Phosphate buffered saline
Tween 20
Sodium azide
The buffer solution is critical to the accuracy of the test as water has containment’s which may alter the accuracy and read of the test.

**Q: Can you test for fentanyl in marijuana with it?**
A: Our kits are mainly used for testing powder substances for fentanyl as it is mostly mixed there, but yes, you will be able to detect fentanyl in marijuana as well. Please, just follow carefully the instructions and feel free to do the test.

**Q: Can I crush a OxyContin pill into powder and test it with this test?**
A: Yes, you can test any powder and substance with this test kit

**Q: is this a urine test?**
A: No, this test is not for testing urine. This test is used for testing liquid and powder substances for Fentanyl and many other Fentanyl analogues.
