Recognized as an effective approach for detecting drug and alcohol consumption, hair testing captures a prolonged history of substance use by embedding biomarkers in the growing hair strands. Harvested near the scalp, hair samples can offer a detection time frame of nearly 3 months for alcohol and drugs. Collecting hair samples is straightforward, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 strands (comparable in size to a #2 pencil) taken closest to the scalp will yield 100mg of hair, which is considered the optimal sample for both screening and confirmation. For EtG add-ons and/or tests exceeding 10 panels, a specimen size of 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair may be used. "Head hair" specifically references scalp hair, while "body hair" pertains to all other types, such as facial and axillary hair.
Process Overview
The laboratory process for handling a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning takes care of the initial sample processing into the laboratory's system. This process verifies that the sample was properly sealed and shipped, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any necessary data entry not covered by an electronic chain of custody system.
Screening offers a preliminary check for substance misuse. Despite being a cost-efficient method to eliminate drug consumption for most samples, a positive screening must undergo confirmation to hold up in legal proceedings. Presumptively positive screenings necessitate further confirmation.
If a specimen appears positive during Screening, additional hair is extracted from the primary sample for the Extraction stage. Here, drugs are isolated from the hair at a significantly lower concentration than other approaches (e.g., urine or oral fluid), which is why hair screening represents the most challenging testing method.
Confirmation for a positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show presumptive positivity are cleansed before confirmation as needed. The complete laboratory protocol, from Accessioning through to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the accreditation of ISO / IEC 17025 standards.
