Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by securing biomarkers within the strands as they grow. When retrieved near the scalp, hair can offer nearly a 90-day detection period for drugs and alcohol. Collection is straightforward, it's relatively tamper-resistant, and shipping is convenient.
A sample measuring 1.5 inches, comprising around 200 hair strands (or the girth of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal amount for screening and confirming results. For EtG assessments or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. In cases where scalp hair isn't obtainable, an equivalent amount of body hair can be used. References to head hair pertain exclusively to scalp hair, while body hair includes all other varieties (such as facial and axillary hair).
Process Overview
The drug test laboratory procedure consists of four principal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in processing a sample within a laboratory's system. This step involves checking that the sample has been sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any manual data entry that isn't captured by an electronic chain of custody system.
Screening provides an initial, rapid assessment for drugs of abuse. While it's an economical way to exclude drug use in most specimens, a positive screening necessitates confirmation for legal acceptability. Specimens with presumptive positive results in Screening must undergo secondary confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the specimen and prepared for Extraction. This stage involves removing drugs from hair at concentrations significantly lower than other testing methods (like urine or oral fluid), highlighting why hair drug tests are notably challenging to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive screening results. Presumptive positive samples are cleaned before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and certified to ISO / IEC 17025 standards.
