Thanks for the advice. And keep it coming.

PS...I searched the internet for hours..and did you the search feature on here, but you can not search for IgG because it is only three characters.
Try the terms "genetic testing" and/or "Human Glycoprotein Immunoglobulin".
Sorry Ive overlooked the fact that youre taking a court-ordered drug test. In that case, court-ordered tests are an entirely different ball game as the person on probation has virtually relinquished all rights (including the right to a fair drug test) normally enjoyed by those taking an employment-related drug test.

Most court-ordered tests are observed, making sample substitution (human or synthetic) not a viable option.
