The effectiveness of hair testing in identifying substance intake has been acknowledged. Hair retains a historical record of substance consumption by encapsulating markers within the strands of the growing hair. When hair is sampled near the scalp, it can reveal drug or alcohol use over approximately a three-month duration. Collection is straightforward, tampering is challenging, and transport is convenient.
Acquiring a 1.5-inch portion comprising roughly 200 hair strands (similar to the size of a #2 pencil) closest to the scalp yields 100mg, the optimal quantity for analysis and verification. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to measure the sample is suggested. In the absence of scalp hair, an equivalent weight of body hair may be procured. Head hair exclusively denotes scalp hair. Body hair includes all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result consists of Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning of a sample's incorporation into a lab's workflow. This step confirms the sample's intact sealing and proper dispatch, assigns a unique LAN (Laboratory Accessioning Number), and completes any pending data not covered by an electronic chain of custody system.
Screening entails a preliminary assessment for drugs of misuse. While this step is economical for identifying drug absence in most samples, legal validity requires that a positive result undergoes confirmation. Samples with a preliminary positive outcome in Screening necessitate further verification.
In instances where Screening indicates a presumptive positive, an additional amount of hair is extracted from the original sample and readied for Extraction. This stage involves extracting drugs from hair at concentrations lower than those used in other techniques (e.g., urine or oral fluid), rendering hair drug screening the most complex method to execute.
Confirmation for any positive results from screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All specimens marked as presumptively positive undergo cleansing prior to confirmation as deemed necessary. The comprehensive lab process from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation alongside the accreditation for ISO / IEC 17025 standards.
