Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair samples can offer up to a 3-month detection timeframe for drugs and alcohol. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.
A sample measuring 1.5 inches, containing about 200 hair strands (approximately the size of a #2 pencil) adjacent to the scalp, yields 100mg of hair, ideal for screening and validation. For EtG, additional tests, or screenings over 10 panels, a 150mg sample is advised. It's suggested to weigh the hair sample using a jeweler’s scale. If scalp hair is not available, a similar amount of body hair may be collected. When we mention head hair, we refer specifically to scalp hair. Body hair encompasses all other hair types, such as facial or axillary hair.
Procedure Outline
The laboratory processing for drug tests consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into the lab system, verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody.
Screening performs an initial, rapid assessment for various drugs. Although Screening is cost-effective for eliminating drug use in most cases, a positive finding must be confirmed to be permissible in legal settings. All samples flagged as positive in Screening undergo additional confirmation.
Should a sample indicate a positive result during the Screening phase, additional hair is extracted from the original sample for the Extraction process. Drugs are then isolated from hair at lower concentrations than in other techniques (like urine or oral fluid), making hair drug testing the most complex method available.
Confirmation for any screening-identified positive result is done through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleansed beforehand. The full lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
