Hair testing is widely regarded as an effective technique for identifying drug and alcohol consumption. Hair captures biomarkers within the strands, offering a prolonged history of substance use. When cut near the scalp, hair can reveal drug and alcohol usage up to a 3-month duration. Hair strands are easy to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch portion of around 200 hair strands (similar to a #2 pencil size) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and validation. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of hair is advisable. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar amount of body hair may be used. Referencing head hair pertains only to scalp strands, whereas body hair encompasses all other hair varieties (facial, axillary, and so on).
Process Overview
The laboratory methodology for a drug test outcomes involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the preliminary procedure entails incorporating a sample into the lab's framework. This step includes ensuring the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input absent in an electronic chain of custody system.
Screening is a swift initial procedure checking for drug presence. Although Screening economically eliminates drug usage for most samples, a positive finding necessitates confirmation for legal acceptability. Tests indicating a presumptive positive outcome in Screening must undergo subsequent verification.
For presumptive positives during Screening, additional hair is extracted from the original sample and readied for Extraction. This phase extracts drugs from the hair at substantially lower concentrations than other methods (e.g., urine or oral fluids), underlining the complexity of performing hair drug screenings.
Confirmation of any positive Screening results is executed through GC/MS, GC/MS/MS, or LC/MS/MS technology. Any presumptive positive samples are cleansed before Confirmation as required. The complete lab procedure, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 certification standards.
