Hair testing is increasingly viewed as an effective method for identifying drug and alcohol consumption. It offers an extended timeline by embedding biomarkers within the hair strand as it grows. When the sample is taken near the scalp, it can reflect a 3-month period of alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
For optimal analysis, a 1.5-inch segment comprising around 200 strands of hair (roughly the width of a #2 pencil) is ideal, yielding about 100mg. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is suggested. We advocate for weighing using a jeweler’s scale. If scalp hair lacks availability, an equivalent amount of body hair can be used. Our use of the term "head hair" exclusively refers to scalp hair. "Body hair" includes all other types like facial or underarm hair.
Process Overview
The laboratory drug testing procedure includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into the lab system. This ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry ignored by an e-chain of custody system.
Screening acts as a preliminary quick scan for drug presence. Though cost-efficient for most samples, a positive in Screening demands confirmation to hold up legally. Any Screening presumptive positives require secondary validation.
Upon a Screening presumptive positive result, additional hair from the sample is used for the Extraction phase. In this part, drugs are removed from the hair at concentrations lower than other methods (e.g., urine or oral fluid), which makes hair drug testing notably complex.
Validation of any positive results from Screening goes through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive results are washed before confirmation as needed. The comprehensive process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair guidelines and accredited to ISO / IEC 17025 standards.
