Hair analysis is increasingly esteemed as an effective method for identifying substance and alcohol consumption. Hair offers an extensive timeline of substance markers by capturing them within the hair’s structural fibers. Acquired near the scalp, hair can present an approximate 3-month detection span for alcohol and drugs. Hair is straightforward to procure, challenging to tamper with, and simple to dispatch.
A 1.5-inch hair sample comprising about 200 strands (approximately the girth of a #2 pencil) near the scalp yields 100mg of hair, an optimal amount for testing and validation. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. Should scalp hair be lacking, an equivalent quantity of body hair is permissible. Reference to head hair pertains exclusively to scalp hair. Body hair encompasses all other hair classifications (facial, axillary, etc.).
Process Overview
The principal procedures entailed in laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary processing of a sample into a lab’s system. This process ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry absent in an electronic chain of custody setup.
Screening comprises a preliminary inspection for substances of misuse. While Screening is economical to dismiss drug utilization in a majority of samples, a positive indication needs validation for courtroom acceptance. Samples presumptively positive during Screening necessitate a successive confirmation.
A presumptive positive sample during Screening prompts additional hair extraction from the main sample preparing it for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing formidable to conduct.
Confirming any positive screen result occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo cleansing prior to Confirmation if needed. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair definition and ISO / IEC 17025 accreditation.
