Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug presence by embedding biomarkers within the fibers of the growing strand. When sampled near the scalp, hair can reveal a detection period of roughly three months for alcohol and drug traces. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A sample measuring 1.5 inches with around 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for screening and verification. For EtG assessments, extra features, and/or examinations beyond 10 panels, a 150mg sample is advised. We suggest using a jeweler's scale for evaluating the specimen weight. If scalp hair is not available, an equivalent amount of body hair can be gathered. References to head hair pertain solely to scalp hair, while body hair denotes all other types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the lab includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary step of integrating a sample into a lab's system. This step consists of ensuring the proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening is a rapid preliminary assessment for drugs of abuse. Although Screening provides a cost-efficient method to dismiss drug use in most samples, a positive result requires confirmation to be permissible in legal proceedings. Presumptive positive samples in Screening must undergo secondary confirmation.
Should a sample show a presumptive positive in Screening, more hair is extracted from the initial sample for the Extraction process. At this stage, drug substances are isolated from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug assays the most challenging method to execute.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation, as necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
