    • A positive test result indicates the presence of FYL only, and does not indicate quantity.  
    • A negative test result does not indicate that no FYL exists in the substance being tested, but only that the presence may be below the test’s detection level.  
    • Overdose Kits LLC does not encourage the production, use, supply, or distribution of illegal drugs or controlled substances in any way. This test is intended for harm reduction purposes only.  
    • A positive or negative test does not indicate that the substance being tested is safe to use. This test is not intended to determine the purity or composition of the substance being tested, or the existence of any other substance. 
    • Overdose Kits LLC cannot verify the accuracy of this test after its expiration date. Storage and procedure instructions must be followed to obtain the most accurate test result.  
    • Any substance expected to contain FYL should be treated with extreme caution as exposure to a small amount can lead to significant health-related complications, respiratory depression, or death.
