The utility of hair testing in identifying substance and alcohol consumption is increasingly recognized. Unlike other methods, hair captures a long-term trace of alcohol and drug use by embedding biomarkers in the hair strand's fibers. When gathered near the scalp, hair samples offer up to a quarter-year detection duration for drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A sample comprising 1.5 inches of hair, around 200 strands (comparable to a #2 pencil's thickness), nearest to the scalp yields about 100mg, optimal for evaluation and verification. For EtG, additions, and tests surpassing 10 panels, a 150mg quantity is suggested. It's preferable to weigh the sample with a precision scale. If scalp hair is lacking, a similar quantity of body hair may be used. When mentioning head hair, we mean scalp hair specifically. All other hair (facial, underarm, etc.) is classified as body hair.
Process Overview
The laboratory processes a drug test result via four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample enters the lab's system, verifying its proper sealing and shipment, assigning it a random LAN (Laboratory Accessioning Number), and completing any data entry missing from an electronic chain of custody system.
Screening offers a preliminary assessment for substance misuse. Though cost-efficient for negating drug use across most samples, positive Screening results need confirmation for court acceptance. Any screenings showing presumptive positivity require further validation.
If Screening indicates presumptive positivity, additional hair is extracted from the sample for the Extraction phase. Here, drugs are extracted at a lower concentration than other methods (e.g., urine or oral fluid), making hair drug tests uniquely challenging to execute.
Confirmation for any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab sequence, from Accessioning to Confirmation, is scrutinized under CAP's (College of American Pathologists) Hair designation and ISO / IEC 17025 standards certification.
