Hair testing is now regarded as an effective means for identifying drug and alcohol usage. Hair captures biomarkers within the fibers of the growing strands, offering a detailed record of substance use. When obtained near the scalp, hair can reveal substance use over a period of up to three months. Collection is straightforward, tampering is quite challenging, and transportation is convenient.
A sample measuring 1.5 inches, consisting of around 200 hair strands similar to a #2 pencil thickness, will yield about 100mg of hair, which is ideal for both screening and confirmation. For tests including EtG, additional panels, or those exceeding 10-drug panels, a specimen amount of 150mg is suggested. It's advisable to use a jeweler's scale for weighing the specimen. Should scalp hair be unavailable, an equivalent portion of body hair can be obtained. References to head hair pertain exclusively to scalp hair. Body hair covers all other forms (such as facial and axillary hair).
Process Overview
The laboratory procedure for processing a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are initially processed into the lab's system. This step includes checking that the sample is correctly sealed and transported, assigning a unique Laboratory Accessioning Number (LAN), and completing any required data entry that wasn’t covered by an electronic chain of custody.
Screening serves as a preliminary assessment for drugs. It is an economical method for excluding drug usage in most cases, yet a positive outcome necessitates further confirmation for legal acceptability. Samples presumed positive during Screening must undergo subsequent confirmation.
In the event of a presumptive positive Screening, additional hair from the original sample is allocated for Extraction. This phase concentrates on extracting drugs at much lower levels compared to other tests (e.g., urine or oral fluid), which renders hair drug testing as a more complex methodology.
Confirmation of positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. If necessary, samples with presumed positive results are washed before confirmation. The complete lab process, from Accessioning through Confirmation, is audited under the College of American Pathologists (CAP) Hair designation, as well as under ISO / IEC 17025 accreditation standards.
