Should you choose Nail Drug Testing?
When drugs are metabolized within a person's body, they continue to travel through the individual's bloodstream. Traces of the drugs are left behind in the body and can be detected in fingernails and toenails. Due to the relatively slow speed at which fingernails and toenails grow, it's possible to detect these traces for months afterward.
This makes nail drug testing an ideal option for those wishing to screen for drug usage at any point in the past eight or so months.
