Hair sampling is widely recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged profile of substance usage by encapsulating biomarkers within the strands. Harvested from near the scalp, hair samples can offer a detection period of nearly three months for alcohol and drugs. Hair is easy to gather, relatively resistant to tampering, and convenient for transport.
A sample measuring 1.5 inches and comprising roughly 200 hair strands (approximately the width of a #2 pencil) adjacent to the scalp equates to 100mg, which is the optimal amount for testing. For EtG analysis, additional examinations, and/or evaluations exceeding 10 panels, a 150mg specimen is advised. Utilizing a jeweler’s scale for weighing the sample is recommended. If scalp hair is not available, a comparable quantity of body hair can be used. When we mention head hair, it’s exclusively scalp hair. Body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The four critical stages in processing drug test results in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of integrating a sample into the lab system. This process confirms the sample was properly sealed and transported, generates a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment for substances of abuse. While it is a cost-efficient method to rule out drug use for most samples, a positive screen must be verified for legal admissibility. All samples testing presumptively positive during Screening necessitate a follow-up confirmation.
In cases where a sample tests presumptively positive during the Screening step, more hair is extracted from the original sample and primed for Extraction. This phase involves isolating drugs from hair at a smaller concentration than other methods (such as urine or oral fluid), highlighting why hair drug screening is particularly challenging.
Confirmation for any positive screen result is done using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positive samples are cleaned before confirmation if required. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair guidelines and complies with ISO / IEC 17025 certifications.
