Long-Term Drug Use Detection You Can Trust

SuretyDNA Testing Services offers Hair Follicle Drug Testing—a highly accurate, lab-based test used to detect chronic or repeated drug use over a 90-day window. This method is ideal for legal, employment, or personal purposes where a longer history of substance use matters.

What Is Hair Follicle Drug Testing?

Hair testing involves collecting a small hair sample (typically from the scalp) and analyzing it in a certified lab to detect drug metabolites that have been incorporated into the hair shaft. Unlike urine or saliva, hair testing reveals patterns of drug use over time, not just recent use.
