I submitted a synthetic Dr Greens Agent -X yesterday to a Labcorp... if I am reading correctly, Labcorp will use an onsite 5 panel kit, if it is negative, then its the end of testing right?
If this is what happens, I dont understand how Ph and Gravity are even calculated from the sample if this is all they do after its negaitve.
Specimen integrity checks (Creatinine, pH and specific gravity) are performed before the actual drug check, using either a seperate assay, or more recently, a multi-panel assay that features creatinine, pH, and SG panels (in either dip card or EZCup forms). The clients choices on LabCorps "test menu" are not limited to just a 5 panel kit. LabCorp offers 7 panel and up.

If your synthetic is known to be fresh, it wouldnt have any problems passing the above integrity checks.
