Hair analysis is recognized as an effective means for identifying substance and alcohol consumption. It provides extensive historical data by capturing biomarkers within the hair strand's fibers as it grows. When hair is sourced near the scalp, it can reveal drug or alcohol use for up to around three months. Collecting hair is straightforward, tampering with hair is relatively challenging, and the sample is convenient to transport.
A segment of hair measuring 1.5 inches and comprising about 200 hair strands (approximately equivalent to the thickness of a #2 pencil) close to the scalp yields around 100mg, the preferred amount for thorough testing and verification. For EtG, additional screenings, or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to use a jeweler’s scale for weighing the sample. Should scalp hair be unavailable, an equivalent volume of body hair can be obtained. By 'head hair,' we mean specifically scalp hair, while 'body hair' encompasses all other forms (like facial or underarm hair).
Process Overview
The laboratory process in analyzing drug testing results encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial handling of a specimen within a lab's system, ensuring the sample's integrity in sealing and transit, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional documentation needed beyond what's included in an electronic chain of custody.
Screening is a preliminary evaluation for signs of substance misuse. It's a cost-effective method to discount drug presence in most samples, yet a positive screen necessitates confirmatory testing to hold up in legal contexts. Any specimens testing presumptively positive in Screening call for further confirmation.
Should a sample show presumptive positivity during Screening, more hair is drawn from the original sample for the Extraction phase. During Extraction, substances are isolated from hair at significantly lower concentrations compared to other forms such as urine or oral fluids, explaining the complexity of conducting hair-based drug testing.
Verification of any initial positive findings utilizes techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptively positive undergo washing before confirmation if required. The complete process, from Accessioning to Confirmation, is monitored under the CAP (College of American Pathologists) Hair classification and meets ISO / IEC 17025 standards.
