Hair & Nail Testing

 

Hair and nail drug tests can detect drug use over a much, much longer period of time compared to urine tests.

These modes of testing reveal drugs or alcohol consumed in the past 5 to 90 days, whereas a urine test typically only detects drug and alcohol use for up to a week. Hair and nail tests should be used to examine someone for repetitious drug use over an extended period of time.
