4.6 pg (picograms)...
It means your son is positive for marijuana.
All drug test are basically done the same way. There is an initial test, usually an immunoassay. It's a way for durg testing companies to quickly screen for negatives. If that tests above a certain threshold, a confirmation test is done.
In the case of marijuana, the confirmation is looking for the active metabolite of marijuana, delta-9 THC.
Here is a link that may help:
As you can see from looking at the table, 4.6 is roughly 15X the 0.3pg limit to test positive on the confirmation.
Hope this helps...
If you have any more questions, shoot me a PM...I'm a medical review officer which means I review all the drug screen results which come into my medical practice.
