Hair analysis has emerged as a robust method for identifying substance and alcohol use. Hair serves as a long-term repository for alcohol and drug biomarkers trapped within the fibers of the developing hair strand. When samples are taken near the scalp, hair may offer a detection span of up to approximately three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment from about 200 hair strands (about the size of a #2 pencil) nearest to the scalp yields approximately 100mg of hair, the optimal sample for screening and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg of the specimen is advisable. We propose weighing the sample with a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair might be sourced. When discussing head hair, we mean scalp hair exclusively. Body hair pertains to all other hair categories (facial, axillary, etc.).
Process Overview
The core procedures in the lab processing of a drug test outcome involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory’s framework. This encompasses ensuring the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not covered by an electronic chain of custody system.
Screening conducts an initial rapid drug abuse assessment. While Screening provides a cost-efficient approach to exclude drug usage in the majority of samples, a positive screen must be verified for court admissibility. Any samples that display presumptive positivity during Screening necessitate a secondary confirmation.
If a sample is presumed positive during the Screening phase, additional hair is extracted from the initial specimen and set for Extraction, where drugs are isolated from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), marking hair drug screening as the most challenging method to carry out.
Confirmation of any positive screening output is carried out through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positive samples are cleansed prior to confirmation as deemed necessary. The full laboratory sequence from Accessioning through to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
