Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance usage by incorporating biomarkers into the hair strand as it grows. When gathered near the scalp, hair offers a detection period of up to about three months for alcohol and drugs. Collection is straightforward, moderately resistant to tampering, and convenient for transport.
A 1.5-inch section of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, ideal for testing purposes. For EtG, supplemental tests, or evaluations exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair cannot be collected, an equivalent quantity of body hair may be used. When specifying head hair, we mean scalp hair exclusively. Body hair encompasses all other types (such as facial or axillary).
Process Overview
The four critical phases in a laboratory's drug test process include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of the sample into the lab’s workflow. It involves checking the sample’s seal and shipment accuracy, assigning a Laboratory Accessioning Number (LAN) randomly, and finalizing any additional data entry not handled by an electronic chain of custody.
Screening entails a preliminary assessment for substance misuse. Although Screening offers a cost-efficient method to dismiss drug consumption in most cases, any positive findings require further confirmation to be legally valid. Samples displaying presumptive positivity during Screening must undergo additional verification.
For samples with preliminary positive results in Screening, additional hair from the original sample is prepared for the Extraction phase. In this step, substances are isolated from hair at lower concentrations compared to other methods (such as urine or oral fluids), highlighting hair drug testing as among the most challenging techniques.
Positive Screening outcomes are confirmed with GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples are cleansed as necessary. The complete laboratory journey from Accessioning to Confirmation is evaluated in line with both the CAP's Hair designation and ISO / IEC 17025 accreditation standards.
