Hair analysis is recognized as an effective method for identifying alcohol and drug consumption. Through capturing biomarkers in the fibers of the growing hair strand, hair offers a prolonged timeline of substance use. When obtained near the scalp, it can reveal alcohol and drug use for a period of up to three months. Hair is easy to gather, moderately resistant to tampering, and straightforward to transport.
A sample measuring 1.5 inches, consisting of around 200 strands (equivalent to a #2 pencil's thickness) nearest the scalp yields 100mg, which is the ideal amount for examination. For EtG, additional tests, and screenings beyond 10 panels, a quantity of 150mg is advised. It’s best to weigh the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types like facial or axillary.
Process Overview
There are four primary phases in the lab analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial integration of a sample into a laboratory's system, which involves ensuring the sample is securely sealed and shipped, allotting a random LAN (Laboratory Accessioning Number), and adding any additional data entry missing from an electronic chain of custody procedure.
Screening acts as a preliminary examination for illicit substances. Although Screening is an inexpensive method to eliminate drug use in most cases, any positive result must be verified to be accepted legally. Samples showing a presumptive positive in Screening necessitate auxiliary confirmation.
In the event a sample shows a presumptive positive during the Screening phase, extra hair is extracted from the sample and readied for Extraction. Here, drugs are drawn from hair at a lower concentration than in other methods (like urine or oral fluid), making hair testing one of the hardest methodologies to implement.
Verification of any positive Screening outcome is executed by GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before verification if required. The complete lab procedure, from Accessioning to Confirmation, is analyzed under the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 accreditation standards.

Note: Despite being often termed "hair follicle tests," the focus is on analyzing the hair strand, not the follicle beneath the scalp.
