Recognized as an effective means to identify drug and alcohol consumption, hair testing captures a history of substance use over time by encapsulating biomarkers in the hair strand's developing fibers. When taken near the scalp, hair enables as much as a three-month detection timeframe for alcohol and drugs. It is straightforward to gather, moderately hard to tamper with, and convenient to transport.
A 1.5-inch hair sample consisting of approximately 200 strands (similar in diameter to a #2 pencil) near the scalp will yield 100mg, the optimal amount for both screening and verification. For EtG, extras, and/or assessments exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for specimen weighing is advisable. In cases where scalp hair is absent, an equivalent body hair amount can be obtained. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial phase of integrating a sample into a laboratory database. This step ensures the sample's sealing and shipment are accurately handled, assigns a unique LAN (Laboratory Accessioning Number), and enters any additional data absent from an electronic chain of custody system.
Screening provides an initial rapid assessment for substance misuse. While Screening is an economical approach to eliminate drug use in most cases, a positive Screening needs validation to be legally acceptable. Samples that are conditionally positive in Screening necessitate further confirmation.
Should a sample reflect a conditional positive in the Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair in notably lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing presents greater challenges.
Verification of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All conditionally positive samples are cleansed prior to confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
