Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. The hair captures a long-term record of substance use by retaining biomarkers within its strands as it grows. When cut near the scalp, hair offers a detection window of up to approximately three months for alcohol and other substances. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
A 1.5-inch section consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides about 100mg of hair, optimal for screening and verification. For EtG, additional tests, and assessments exceeding 10 panels, 150mg of the sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair cannot be collected, an equivalent portion of body hair can serve as a substitute. References to head hair pertain specifically to scalp hair, while body hair covers all other types (such as facial or axillary hair).
Process Overview
The drug test result processing in the laboratory involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the integration of a sample into the lab's system. It verifies the sample's proper sealing and shipping, allocates a unique LAN (Laboratory Accessioning Number), and completes any missing data entries not provided by an electronic chain of custody framework.
Screening entails a preliminary swift check for substances of abuse. Although Screening economically helps to discard drug usage in most samples, a positive outcome in this phase necessitates confirmation to be legally valid. Positive samples from Screening require additional verification.
When a sample is flagged as positive during Screening, additional hair is extracted from the initial sample, prepared for Extraction, where drugs are pulled from hair at significantly lower levels than other methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most challenging to execute.
Any positive Screening result undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All indicative positive samples are cleansed before confirmation, as needed. The complete lab process, from Accessioning to Confirmation, undergoes review according to both the CAP (College of American Pathologists) Hair classification and the adherence to ISO / IEC 17025 standards.
