Hair analysis is now regarded as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers within the hair strand as it grows. When taken from near the scalp, hair can exhibit a detection window of approximately 3 months for identifying alcohol and drugs. Hair is straightforward to gather, challenging to tamper with, and simple to send.
A sample measuring 1.5 inches, consisting of about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp, yields 100mg of hair, the preferred quantity for both screening and verification. For EtG, additional tests, and/or screenings beyond 10 panels, 150mg of the hair sample is advised. It's suggested to use a jeweler’s scale to measure the sample weight. If scalp hair is not accessible, a similar volume of body hair might be used. When mentioning head hair, we mean scalp hair exclusively. Body hair denotes all other types of hair (like facial and axillary hair).
Process Overview
The primary steps in a lab's drug testing process cover Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails initially processing a sample within a lab’s system. This stage includes confirming that the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic chain of custody system.
Screening acts as an initial swift assessment for drugs of misuse. Although Screening represents a budget-friendly strategy to negate drug use in most samples, a positive outcome requires confirmation for court acceptability. Any samples appearing positive in Screening necessitate further confirmation.
Should a specimen test positive in the Screening stage, more hair is taken from the original sample and prepped for Extraction. Here, drugs are extracted from the hair at lower concentrations than in other techniques (such as urine or oral fluids), illustrating why hair drug screening is among the toughest methodologies.
Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo a wash before confirmation as necessary. The complete lab process from Accessioning to Confirmation is conducted under the scrutiny of both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
