The use of hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair offers a long-term record of alcohol and drug presence by locking in biomarkers within the growing hair shaft. When sourced near the scalp, hair provides up to a 3-month detection period for alcohol and drugs. It is straightforward to collect, difficult to tamper with, and convenient to transport.
A sample of about 1.5 inches or 200 hair strands (comparable to a #2 pencil) closest to the scalp results in 100mg of hair, which is ideal for screening and validation. For EtG, additional tests, or more than 10 panels, a specimen amount of 150mg is suggested. Weighing the sample on a jeweler's scale is advisable. If scalp hair is absent, an equal volume of body hair can be collected. Head hair refers strictly to scalp hair, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of the sample within a lab’s system. This step ensures the sample was correctly sealed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any missing information not available through an electronic chain of custody system.
Screening offers a preliminary assessment to detect drugs. While cost-effective for ruling out drug consumption in most samples, a positive screening outcome needs confirmation for court admissibility. Samples presumed positive in Screening necessitate a follow-up confirmation.
A sample presumed positive at the Screening phase leads to additional hair extraction from the initial sample for preparation in the Extraction phase. Here, drugs are retrieved from the hair at substantially lower concentrations than other methods (e.g., urine or oral fluid), affirming the complexity of hair drug screening.
Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is overseen for compliance both with the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
