Hair analysis has emerged as an influential method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by securing biomarkers within the strands' structure. When taken near the scalp, it offers roughly a 3-month timeframe for detection of drugs and alcohol. Hair collection is straightforward, relatively tamper-proof, and convenient for transport.
A sample length of 1.5 inches comprising around 200 hair strands (approximating the thickness of a #2 pencil), collected closest to the scalp, yields 100mg, which is the optimal sample size for initial screening and verification. For EtG, additional tests, or panels beyond ten, a specimen weighing 150mg is suggested. It's advisable to measure using a jeweler’s scale. In the absence of scalp hair, a similar volume of body hair can be used. The term 'head hair' strictly refers to scalp hair. 'Body hair' encompasses all other forms (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing for a drug testing result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial step of integrating a sample into the laboratory system. This process involves confirming the secure sealing and proper shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic custody chain.
Screening is a preliminary assessment for substances. While it represents an economical method to exclude drug presence in most samples, any positive finding must undergo confirmation to be legally valid. Any samples flagged as possibly positive in Screening require additional validation.
For samples tested positive in the Screening phase, further extraction of hair from the primary sample is conducted. In Extraction, substances are isolated from hair at significantly reduced concentrations than other methods (like urine or oral fluid), rendering hair drug testing as one of the most complex techniques.
Confirmation of a positive result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed before confirmation if needed. The entire process from Accessioning through Confirmation adheres to standards under both the CAP (College of American Pathologists) Hair designation and an ISO / IEC 17025 accreditation.
