Hair testing is widely recognized as an effective means for detecting alcohol and drug usage. The hair strands capture biomarkers within their fibers as they grow, providing a long-term record of substance use. When collected near the scalp, hair can reveal drug and alcohol use spanning up to about three months. It is easy to collect, challenging to tamper with, and convenient to send.
Collecting a 1.5-inch segment of roughly 200 hair strands (comparable to the size of a #2 pencil) from the scalp yields approximately 100mg of hair, which is optimal for initial screening and verification. For EtG, add-ons, and/or panels exceeding 10, a 150mg specimen is advised. We recommend using a jeweler’s scale for precise measurement. If scalp hair is not available, a similar amount of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
There are four critical phases in the laboratory analysis of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample enters the laboratory’s workflow. This step confirms that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any additional information not furnished through an electronic chain of custody system.
Screening performs an initial assessment for drugs of misuse. While this procedure is cost-efficient for excluding drug use in most cases, a positive screen must be verified for legal admissibility. Samples that show presumption of positivity during Screening must undergo additional validation.
If a sample is presumed positive during Screening, further hair is taken from the original sample and readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than alternative methods (such as urine or oral fluid), which makes hair drug screening notably complex to execute.
Confirmation of any positive Screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS technology. All samples presumed positive are cleaned before confirmation if required. The full process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair specification and accreditation to ISO / IEC 17025 standards.

Note: Although often termed "hair follicle tests," the analysis is performed on the hair strand itself, not on the follicle beneath the scalp.
