Human Glycoprotein Immunoglobulin G (IgG) is not part of drug testing/validity testing protocols. Sure there are (or were) dipsticks available to check for the presence of IgG, but under the US Dept of HHS regulations, validity testing requires confirmation complete with quantitive values reported. Since exact quantitive values for IgG are impossible without using complicated and expensive testing (such as DNA), its therefore illegal for labs practicing in the US to conduct IgG, or any other form of genetic testing on urine samples collected for a drug test, unless written authorization is granted by the donor. The authorization is made on an entirely seperate and detailed consent form.
The labs are only allowed to test for drug metabolites, creatnine, specific gravity, pH, and excessive nitrites. As long as your QF batch is not old and was kept away from direct sunlight, it will pass these checks.
