Utilizing hair analysis for identifying drug and alcohol consumption has gained recognition as an efficient method. Hair preserves a long-term record by capturing biomarkers within the fibers of the growing strands. When collected near the scalp, hair can reveal drug and alcohol use for a period up to approximately 3 months. Collection of hair is straightforward, challenging to tamper with, and convenient to transport.
To obtain an optimal sample for screening and confirmation, a 1.5-inch segment of approximately 200 strands (similar to a #2 pencil in size) nearest to the scalp should be provided, yielding 100mg of hair. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. Verifying weight with a jeweler’s scale is suggested. If scalp hair is unobtainable, an equivalent amount of body hair could be utilized. When mentioning head hair, it pertains solely to scalp hair, while body hair covers other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial sample processing into a laboratory’s system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing extra data entry if not covered by an electronic chain of custody system.
Screening is a preliminary check for drug misuse. It offers a cost-efficient method to eliminate drug usage suspicions for most samples; however, legal admissibility requires a confirmed positive screen. Presumptively positive Screening samples necessitate secondary confirmation.
When a sample tests presumptively positive during Screening, additional hair is taken from the original specimen for Extraction. Here, drugs are extracted at concentrations much lower than in other methods (e.g., urine or oral fluid), affirming hair drug screening as a sophisticated methodology.
Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS approaches. Prior to confirmation, necessary presumptive positive samples undergo a washing process. A comprehensive review of the whole laboratory process, from Accessioning to Confirmation, falls under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although commonly referred to as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
