The use of hair for drug and alcohol detection is recognized as a highly effective method. Hair captures a timeline of drug and alcohol consumption by embedding biomarkers within the hair as it grows. When taken from near the scalp, this method can offer a detection period of up to three months for various substances. Hair sample collection is straightforward, tamper-resistant, and easily transported.
A sample consisting of approximately 200 hair strands, measuring around 1.5 inches (about the girth of a #2 pencil) from the scalp, yields 100mg of hair, which is optimal for both initial testing and follow-up verification. For EtG, expanded panels, or screenings beyond 10 panels, 150mg of sample is advisable. Utilizing a jeweler's scale to measure the sample is suggested. In the absence of head hair, body hair in an equivalent volume can be used. "Head hair" specifically refers to hair collected from the scalp. All other types of hair, such as facial or underarm hair, are categorized as "body hair."
Process Overview
The laboratory testing of hair for drugs involves four critical phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is processed into the laboratory's system. This step checks that the sample is properly sealed and sent, assigns it a random Laboratory Accessioning Number (LAN), and completes any data inputs not covered by electronic custody systems.
Screening provides an initial swift review for substance use. Though Screening efficiently rules out drug use in most samples, any positive findings need further testing for legal validation. Samples testing positive in Screening require additional confirmation.
Should the Screening indicate potential positivity, extra hair from the original sample is prepared for Extraction. At this stage, substances are separated from the hair at more minute concentrations compared to other testing methods (such as urine or saliva), highlighting the complexity of hair drug testing.
Confirmation for any positive result from Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples are washed before confirmation if required. The entire procedure from Accessioning to Confirmation is monitored under the guidelines of the College of American Pathologists (CAP) Hair designation and accredited by the standards of ISO / IEC 17025.

Note: Although commonly called "hair follicle tests," the analysis focuses on the hair strand, not the follicle located beneath the scalp.
