Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Through capturing biomarkers in the strands of hair, this method yields a comprehensive longitudinal record of alcohol and other substance use. Hair specimens collected near the scalp can offer up to nearly a 3-month period for detecting substances. Collecting hair is straightforward, hard to tamper with, and convenient for transportation.
Securing a 1.5-inch section of around 200 strands of hair (akin to the diameter of a #2 pencil) from the scalp supplies 100mg of hair, which is the optimal portion for both screening and confirmation. In cases of EtG, supplementary tests, or evaluations beyond 10-panel, 150mg of the sample is advised. Utilizing a jeweler's scale to weigh the specimen is recommended. Should scalp hair not be obtainable, a comparable quantity of body hair can be taken. In the context of head hair, it specifically means scalp hair. Body hair encompasses all other types of hair (like facial and axillary).
Process Overview
The laboratory processing of a drug test result involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample inside a laboratory's infrastructure. This process includes checking if the sample was properly sealed and sent, generating a random LAN (Laboratory Accessioning Number), and completing further data entry if not available through an electronic chain of custody system.
Screening represents an initial rapid evaluation for drugs of abuse. Though Screening serves as a cost-effective means to eliminate drug consumption for most samples, a screen yielding a positive result necessitates confirmation for legal acceptability. Any samples showing a presumptive positive during Screening mandate secondary verification.
If a sample tests presumptively positive during Screening, additional hair is harvested from the original sample for Extraction. Here, drugs are retrieved from hair at much lower concentrations than other types of testing (such as urine or oral fluid tests), which is why hair drug analysis stands as the most challenging method.
Verification of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleansed preceding confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.
