Alright we have covered the single panel test strips but if you believe there is more than just THC or cocaine in your system then you might want to explore the use of the 5 Panel Home Urine Test Strip.  Some people call us and are terrified that they have to take a urine drug test.  They mistakenly believe that they will test positive after just smoking marijuana that the lab will run five separate and increasingly analytical tests to determine the amount of THC in their system.  This is not what a 5 Panel Home Urine Drug Test Strip does.  The 5 panels represent five different substances that the lab is testing for.  The same holds true for ten panel tests strips, twelve panel test strips, etc.  With a 5 panel Home Drug test Strip you can determine if you are going to test positive for these five substances: marijuana (THC), amphetamines, Morphine / opiates, methamphetamines and cocaine.  These are the five most common substances that are abused among the general population according to The Substance Abuse and Mental Health Services Administration (SAMHSA).  The cutoff levels for these drugs are the same as the single panel tests strips.  Marijuana (THC) has a cutoff level of 50 ng/ml, amphetamines has a cutoff level of 1000 ng/ml, morphine / opiates has a cutoff level of 2000 ng/ml, methamphetamines has a cutoff level of 500 ng/ml and cocaine has a cutoff level of 300 ng /ml.
