Hair analysis is now recognized as a significant method for identifying substance consumption. Hair retains a record over time of alcohol and other substances by embedding biomarkers in its fibers as it grows. When taken near the scalp, it offers a detection timeline extending up to about three months for alcohol and drugs. Hair is easy to gather, relatively hard to tamper with, and simple to transport.
A hair sample of 1.5 inches comprising roughly 200 hairs (akin to the girth of a #2 pencil) nearest the scalp yields 100mg, which is optimal for both screening and confirming. For tests such as EtG, additional tests, or those surpassing 10 panels, 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be absent, an equivalent quantity of body hair can be secured. "Head hair" specifically denotes scalp hair. "Body hair" includes all other types (such as facial or armpit hair).
Process Overview
The essential stages in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into a lab's database. This step checks that the sample is sealed and transferred properly, allocates a random LAN (Laboratory Accessioning Number), and handles any extra data input not available through an electronic chain of custody solution.
Screening provides a preliminary rapid overview for substance misuse. Although Screening economically aids in eliminating drug use in most samples, a positive outcome demands subsequent validation for legal acceptability. Any samples showing potential positivity in Screening must undergo additional verification.
Should a sample result as potentially positive during the Screening phase, more hair is extracted from the initial sample for the Extraction step. In this phase, drugs are retrieved from hair at lower concentrations compared to other procedures (for example, urine or saliva), making hair drug assessment the most complex procedure to execute.
Validation of any positive Screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo a prescribed wash before confirmation, as needed. The complete lab sequence from Accessioning to Confirmation operates under CAP (College of American Pathologists) Hair designation oversight and complies with ISO / IEC 17025 accreditation standards.
