Webinar - Hair Color Bias

Join us for a webinar that takes you through the benefits and limitations of drug testing keratin matrices (i.e. hair, nail). We discuss how drugs are incorporated into hair and nail, and how some factors affect the tests, such as chemical treatments and pigment. Specifically we discuss case studies regarding natural hair pigment (color), and how hair as a specimen compares to nail.
