Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair collects a prolonged record of drug and alcohol use by capturing biomarkers within its developing strands. When gathered near the scalp, it can show drug and alcohol presence for up to around three months. This method is straightforward to gather, offers resistance to tampering, and is simple to transport.
Gathering a 1.5-inch section of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp provides 100mg of hair, which is the perfect sample size for assessment and verification. For EtG tests or those beyond 10-panel screens, 150mg of hair is advisable. It's best to weigh the hair sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair, whereas body hair implies all other types, like facial, axillary, etc.
Process Overview
The hair testing procedure for drugs consists of four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is where a sample is initially processed by the lab’s system. This step includes checking that the sample was sealed correctly for shipping, assigning a random LAN (Laboratory Accessioning Number), and finishing any missing data entry that isn’t provided by an online chain of custody system.
Screening is an initial review to detect substances of abuse. Although Screening is cost-efficient for eliminating drug usage in most cases, a positive screening necessitates confirmation for legal acceptance. Samples that presumptively test positive during Screening must be further confirmed.
When a sample tests presumptively positive during Screening, additional hair is taken from the initial sample and processed for Extraction. At this stage, drugs are extracted from hair at much lower concentrations than other tests such as urine or oral fluid, making hair screening the most complex method.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleaned before confirmation if needed. This entire process from Accessioning through Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
