Recently, hair follicle drug testing has become a preferred method over traditional urine tests by employers, courts, and substance abuse experts. Entities with zero-tolerance policies favor hair tests, which offer a 90-day detection window and are very hard to tamper with, despite urine tests being more precise for happenings within the past 5 days.

Hair analysis is regarded as an effective method for identifying the use of drugs and alcohol. Hair captures a prolonged record of substances by embedding biomarkers within the strands as they grow. When taken from near the scalp, hair can provide insights into drug and alcohol usage over a period of roughly three months. Hair samples are easy to gather, relatively tamper-resistant, and simple to transport.
A hair sample measuring 1.5 inches, consisting of about 200 strands (approximately the thickness of a #2 pencil) and cut closest to the scalp, yields 100mg of hair, which is optimal for both screening and verification. For EtG, extra tests, or when requiring more than 10 panels, a sample of 150mg is preferable. We suggest using a jeweler’s scale for accuracy. In cases where scalp hair is not accessible, an equivalent amount of body hair is suitable. By head hair, we mean scalp hair exclusively, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The process in the lab for processing a drug testing result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample’s initial setup within the laboratory’s framework. This involves making sure the sample is securely sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and filling in any required data not already provided by an electronic custody system.
Screening is a preliminary evaluation for illicit substances. While Screening efficiently rules out drug use for most samples, a positive outcome must be verified for legal acceptability. Samples flagged as potentially positive in Screening need further confirmation.
When a sample shows potential in the Screening phase, additional hair is extracted from the initial sample for Extraction. Here, substances are separated from hair at lower levels compared to other methods (ex. urine or saliva), adding complexity to hair drug testing procedures.
Confirming a positive Screening result employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All possibly positive samples undergo cleansing before confirmation as required. The resulting laboratory operation, from Accessioning to Confirmation, is audited by both the CAP (College of American Pathologists) Hair program and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although often called "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp.
