Hair evaluation is increasingly recognized as an effective approach for identifying substance and alcohol use. Hair captures a historical record of intoxicants by embedding indicators within its evolving structure. When obtained near the head's surface, hair can offer insight into substance and alcohol exposure over a span of nearly three months. It is easy to collect, challenging to tamper with, and straightforward to transport.
A segment of hair measuring 1.5 inches, roughly 200 individual hairs (similar to a #2 pencil in diameter) near the head, yields 100mg—ideal for preliminary and confirmatory examinations. For EtG and/or evaluations exceeding 10 categories, 150mg is preferable. We suggest assessing the quantity using a jeweler’s scale. If head hair is not accessible, a comparable volume of body hair is acceptable. "Head hair" refers exclusively to hair on the scalp. "Body hair" encompasses all other types (e.g., facial, axillary).
Processing Workflow
The lab process for analyzing a drug sample encompasses four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates a specimen into the lab's system. This step checks whether the specimen was appropriately sealed and conveyed, assigns a unique LAN (Laboratory Accessioning Number), and completes other incoming data requisites potentially lacking from an automated chain of custody process.
Screening is a preliminary examination to detect drug presence. Although Screening serves as a cost-efficient method to eliminate drug use suspicion in most samples, a conclusive result is needed for legal admissibility. Specimens suggesting the presence of substances during Screening demand further verification.
Should a sample test positively during the Screening phase, more hair is retrieved for the Extraction process. This involves drug retrieval from hair at a reduced concentration compared to other techniques (e.g., urine or saliva), rendering hair drug assessments the most complex to execute.
Verification of a positive screening outcome happens through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing positive in the preliminary check are cleansed before final analysis, as necessary. The entire evaluation cycle from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair category and upholds ISO / IEC 17025 criteria.
