Hair testing is renowned as an effective method for identifying drug and alcohol usage. Hair captures a comprehensive history of substance use by embedding biomarkers within its growing strands. When sourced near the scalp, it can offer a detection timeframe of up to 3 months for both alcohol and drugs. The collection of hair samples is straightforward, challenging to tamper with, and simple to send.
A section measuring 1.5 inches from about 200 hair strands (approximating the thickness of a #2 pencil) nearest to the scalp will yield 100mg, which is the ideal quantity for conducting both screening and validation. For EtG, optional add-ons, or tests exceeding 10 panels, a sample size of 150mg is advisable. Utilizing a jeweler's scale to weigh the sample is suggested. In cases where scalp hair is unavailable, an equivalent sample of body hair is permissible. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair categories (such as facial and armpit hair).
Process Overview
The laboratory processing of a drug test result is structured in four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system, which involves verifying proper sample sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and resolving any supplementary data input that isn't captured by an electronic chain of custody procedure.
Screening presents an expedient assessment for drugs of abuse. Although Screening is a cost-efficient strategy to discount drug use across most specimens, a positive outcome requires confirmation to be legally valid. Samples with a presumptive positive result in Screening necessitate follow-up Confirmation.
If a sample yields a presumptive positive during Screening, additional hair from the primary sample is procured for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), indicating why hair drug screening is one of the most demanding techniques to execute.
Positive Screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are pre-washed as appropriate before Confirmation. The complete lab process, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards for accreditation.
