Hair testing has emerged as a significant means for identifying drug and alcohol consumption. The fibers of the incrementally growing hair strand capture biomarkers, offering a long-duration overview of substance use. When collected proximate to the scalp, hair can provide a detection timeframe of up to three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch segment comprising approximately 200 hair strands (equivalent to the circumference of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample size for screening and conclusive analysis. For EtG, supplementary tests, and/or analyses exceeding 10 panels, a sample weighing 150mg is optimal. Using a jeweler’s scale for weighing the sample is advised. Should scalp hair be inaccessible, a comparable quantity of body hair may be gathered. When discussing head hair, it pertains exclusively to scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial intake of a sample into a laboratory’s procedures. This entails confirming proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any remaining data inputs not captured by an electronic chain of custody system.
Screening serves as an expedited assessment for drugs of abuse. While it presents a cost-effective avenue to eliminate drug usage suspicion in the majority of samples, a positive screen necessitates confirmation to qualify in legal contexts. Samples preliminarily positive in Screening require secondary verification.
If a sample is provisionally positive during Screening, additional hair is retrieved from the initial sample for the Extraction phase. In this stage, drugs are extracted from hair at markedly lower concentrations compared to other methods (i.e., urine or oral fluid), underscoring the complexity of performing hair drug screening.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS or LC/MS/MS. All preliminary positive specimens undergo washing preceding confirmation as warranted. The entire laboratory sequence from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
