Hair testing is recognized as an effective method for detecting alcohol and drug use by capturing biomarkers within the strands of growing hair. By collecting hair strands near the scalp, it offers a long-term detection period of up to 3 months. Hair sampling is straightforward to gather, challenging to tamper with, and uncomplicated to transport.
A 1.5-inch hair sample consisting of approximately 200 strands (approximately the size of a #2 pencil) next to the scalp will generate about 100mg of hair, the preferred sample size for analysis. For EtG, additional testing, and tests exceeding 10 panels, a 150mg specimen is suggested. Using a jeweler’s scale is recommended to measure the specimen. In cases where scalp hair is not obtainable, an equal quantity of body hair is an acceptable substitute. Terminology referencing head hair pertains exclusively to scalp hair. Body hair encompasses other types such as facial and axillary hair.
Process Overview
The laboratory evaluation of a drug test result encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial introduction of a sample into a laboratory's framework, including verifying proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody.
Screening conducts an initial, rapid assessment for substances of abuse. While it serves as a cost-sensitive technique to eliminate drug presence in most samples, a positive screening necessitates confirmation for court admissibility. Samples indicating a presumptive positive in Screening require subsequent confirmation.
If Screening infers a positive result, additional hair is extracted from the sample for further processing in Extraction. Drugs are then isolated at lower concentrations from hair than other mediums (e.g., urine or oral fluid), making hair drug screening distinctively challenging to execute.
Confirmation of positive screening outcomes is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptively positive samples undergo washing before confirmation if needed. The comprehensive lab process, from Accessioning through Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair certification and ISO/IEC 17025 accreditation.
