Hair examinations are now regarded as an effective means for identifying alcohol and drug usage. Hair serves as a long-lasting record of alcohol and drug consumption by embedding biomarkers within the strands as they grow. When cut near the scalp, hair can offer nearly a 3-month time frame for detecting alcohol and drugs. It is easy to collect, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the circumference of a #2 pencil) nearest the scalp will yield 100mg of hair, the perfect sample amount for analysis and verification. For EtG, additional tests, or panels above 10, a 150mg sample is advised. It is suggested to measure the sample on a jeweler's scale. If scalp hair isn't available, a comparable quantity of body hair can be gathered. When mentioning head hair, it pertains exclusively to scalp hair. Body hair refers to all other hair types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug screening result encompasses four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary intake of a sample into a laboratory's system. This entails confirming the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not managed by an electronic chain of custody framework.
Screening provides a preliminary rapid assessment for drugs of abuse. While Screening offers a economical means to exclude drug use in the bulk of samples, a positive screening must be verified for it to be valid in legal proceedings. Any sample signaling a tentative positive during Screening necessitates a secondary confirmation.
If a sample exhibits a tentative positive during the Screening phase, additional hair is extracted from the primary sample and readied for Extraction. At this step, drugs are isolated from hair at a significantly lower concentration than in other methods (e.g., urine, oral fluid), underscoring the complexity of hair drug screening as a methodology.
Verification of any positive screen result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are tentatively positive undergo a wash before confirmation, if required. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair category and the accreditation in accordance with ISO / IEC 17025 standards.

Limitations:
Note: Despite commonly being called "hair follicle tests", the process actually examines the hair strand, not the follicle beneath the scalp.
