NarcoPouch® Safety & Procedure Tips

NOTE: Field tests are designed to confirm your probable cause. Do not use field tests as the sole element in your probable cause. Whenever you have results that are questionable, always err on the side of a negative reading and forward your suspected material to the Crime Lab for verification.
-Due to the variations in quality and quantity of substance you enter into a field test, be aware that the colors you obtain are designed to only match the family of colors described on the front of the test pouch. Be certain to agitate the pouch thoroughly after breakage of each ampoule.
-Do not keep the field tests as part of your evidence package. This is due to the colors not lasting for long periods of time. Also, you are not able to show multiple positive results, such as the blue to pink to pink over blue in the Cocaine HCl and Crack Test.

-Always dispose of the field tests following your presumptive test and take good notes showing the resultant color reactions in each ampoule.
-As a safety precaution, always wash your hands thoroughly following the completion of your field testing.
