Hair assessment has become recognized as an effective mechanism for identifying drug and alcohol consumption. Hair retains a comprehensive historical record of substances by embedding biomarkers in the structure of the developing hair fiber. Hair, when harvested close to the skin, may present a detection window of as much as 3 months for substances, including alcohol. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A section measuring 1.5 inches, consisting of roughly 200 hairs (akin to the diameter of a #2 pencil) nearest to the skin, yields approximately 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional elements, or tests extending beyond 10 panels, it is advisable to collect 150mg. It's recommended to weigh the sample on a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair is acceptable. ‘Head hair’ specifically references scalp hair, whereas 'body hair' encompasses all other kinds of hair (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug testing results involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the first phase, wherein a sample is incorporated into a lab's system. This procedure includes confirming that the sample was sealed and dispatched correctly, generating a random LAN (Laboratory Accessioning Number), and completing outstanding data entry absent from an electronic chain of custody system.
Screening performs an initial simple examination for substances of misuse. While this stage economically eliminates drug presence in most samples, positive identifications must be validated to be court-acceptable. Samples that return a tentative positive in Screening do necessitate subsequent verification.
Samples registering a preliminary positive in Screening proceed to Extraction, requiring more hairs from the initial batch for preparation. At this stage, drugs are extracted at significantly lower concentrations compared to other procedures (e.g., urine or saliva), which accounts for the complexity of hair drug tests.
Verification of any Screening positives is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positives undergo washing per requirement. The whole sequence from Accessioning through to Confirmation is reviewed consistent with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
