Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Through its fibers, the hair captures long-term biomarkers indicative of substance use. Collecting hair near the scalp can reveal alcohol and drug usage within an estimated 3-month timeframe. Hair collection is straightforward, relatively tamper-resistant, and convenient for transportation.
A 1.5-inch hair segment, consisting of roughly 200 strands (comparable to a #2 pencil's thickness) closest to the scalp, provides 100mg suitable for both screening and confirmation. For EtG, extended panels, or tests beyond 10 panels, a 150mg sample is advisable. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't available, an equivalent volume of body hair can be taken. 'Head hair' refers explicitly to scalp hair. 'Body hair' encompasses all other types (such as facial, axillary, etc.).
Process Overview
The key phases in laboratory processing for drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample’s initial integration into a laboratory’s system, ensuring it was sealed and shipped accurately, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entries missing from an electronic chain of custody system.
Screening serves as an initial check for drug abuse substances. It’s an affordable way to determine no drug usage in most samples; however, legal acceptance requires confirmation of positive results. Samples that present a presumptive positive in Screening need subsequent confirmation.
On presumption of positivity after Screening, further hair is gathered from the original sample and prepared for Extraction. Here, drugs are extracted from hair in significantly lesser concentrations compared to other methods (e.g., urine or oral fluids), making hair drug analysis highly complex.
Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as needed. The entire laboratory process, from Accessioning to Confirmation, meets both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
