Hair analysis is now acknowledged as an effective method for identifying substance and alcohol consumption. Hair captures a chronological record of substance markers in its developing strands. When cut near the scalp, it can indicate drug and alcohol usage for up to a quarter of a year. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A sample of 1.5 inches, comprising around 200 hair strands (approximately equivalent to a #2 pencil's thickness) next to the scalp provides 100mg, the standard quantity for analysis. For EtG, additional markers, and/or tests exceeding 10 panels, it's advised to gather 150mg of hair. It's important to use a precision scale, like a jeweler’s, for weighing. In the absence of scalp hair, a similar quantity of body hair is acceptable. Reference to head hair denotes only scalp hair, while body hair encompasses all other types (beard, armpit, etc.).
Process Overview
The laboratory drug testing process encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates the specimen into a lab's system, ensuring correct sealing and transport, assigning a unique LAN (Laboratory Accessioning Number), and handling any needed data input not covered by an electronic custody chain.
Screening performs an initial assessment for substance misuse. Though cost-effective, a positive screening result necessitates verification to be legally valid. Any presumptive positive results require subsequent confirmation.
When a sample is presumptive positive during Screening, additional hair is utilized for Extraction. Here, substances are isolated from hair at significantly reduced concentrations compared to other methods (e.g., urine or saliva), making this the most complex form of drug testing.
Positive screening results are validated through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives undergo necessary washing. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes scrutiny under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
