Hair testing is now recognized as an effective method for detecting drug and alcohol usage. Hair reveals a prolonged record of alcohol and drugs by encapsulating biomarkers in the strands as hair grows. When sourced near the scalp, hair offers a detection timeframe of up to nearly three months for alcohol and drugs. The collection of hair is straightforward, not easily tampered with, and convenient to transport.
A 1.5-inch segment of around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, the optimal amount for screening and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for specimen weighing is recommended. If scalp hair cannot be obtained, a similar quantity of body hair may be gathered. References to head hair pertain specifically to scalp hair. Body hair includes all other types, such as facial or axillary hair.
Process Overview
The laboratory processing of a drug test result is composed of four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the integration of a sample into a lab’s system initially. This ensures the sample is correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry missing from an electronic chain of custody system.
Screening is a preliminary and rapid assessment for drugs. Although Screening is a cost-effective strategy to dismiss drug usage for most samples, positive results in Screening must be confirmed for legal acceptability. Any samples that are positive in Screening must undergo secondary confirmation.
For a positive result in the Screening phase, additional hair is extracted from the original sample for Extraction. At this stage, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or saliva), making hair drug testing the most challenging methodology.
Confirming any positive result from screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test positive preliminarily are cleansed before confirmation if needed. The full laboratory sequence from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to the ISO / IEC 17025 standards.
