Hair analysis is increasingly regarded as an effective approach for identifying drug and alcohol consumption. Hair captures an extended record of alcohol and drug use by embedding biomarkers within the strands of developing hair. When harvested from near the scalp, hair can detect alcohol and drug presence for up to roughly a 3-month period. The collection of hair is straightforward, relatively hard to tamper with, and simple to transport.
Obtaining a segment of hair measuring 1.5 inches and consisting of approximately 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp provides 100mg, which is the optimal amount for testing and verification. For assessments involving EtG, extra specifications, and/or panels exceeding ten, a sample size of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be used. ‘Head hair’ refers exclusively to scalp hair, whereas ‘body hair’ includes all other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result consists of four principal stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory’s system. This phase involves ensuring the sample is properly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entries not provided by a digital chain of custody system.
Screening involves performing an initial rapid evaluation for drugs of misuse. Although Screening is a cost-efficient method to exclude drug usage in most samples, any positive result from the screening must be validated to be admissible in legal proceedings. Any samples showing presumptive positivity in the Screening phase need secondary confirmation.
If a sample shows presumptive positivity at the Screening stage, additional hair is extracted from the original sample for further processing in Extraction. At this point, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which explains why hair drug testing is among the most challenging methodologies.
Verification of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleaned as required before confirmation. The entire laboratory process from Accessioning to Confirmation is supervised in line with both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
