Hair testing has gained recognition as an effective method for identifying drug and alcohol use. Hair captures biomarkers within the strands, providing a long-term record of alcohol and drug usage. When collected near the scalp, hair offers a detection period of up to roughly three months for these substances. Hair is easy to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch section of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample size for screening and confirming results. For tests including EtG, add-ons, or those exceeding 10 panels, 150mg of the specimen is advised. Utilizing a jeweler's scale to weigh the specimen is suggested. If scalp hair is not available, an equivalent amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types, such as facial and axillary hair.
Process Overview
The laboratory processing of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of incorporating a sample into a laboratory's system, involving verification of proper sealing and shipment, assignment of a random LAN (Laboratory Accessioning Number), and completion of any data entry not supplied by an electronic chain of custody system.
Screening serves as an initial rapid assessment for drugs of abuse. While it is economical for excluding drug usage in most samples, a positive screening requires confirmation to be legally valid. Any samples preliminarily positive in Screening necessitate a secondary confirmation.
If a sample tests presumptively positive in the Screening phase, additional hair is taken from the original specimen for Extraction. During this phase, drugs are extracted from hair at concentrations lower than those in other methods (e.g., urine or oral fluid), making hair drug screening a more complex methodology to execute.
Confirmation of any positive results from screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is overseen by both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
