Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive historical record of alcohol and drug intake by encapsulating biomarkers within the strands' fibers as they grow. Collected near the scalp, hair can offer nearly a 3-month detection range for both alcohol and drugs. It is easy to collect, difficult to tamper with, and simple to transport.
A 1.5-inch section consisting of roughly 200 hair strands (approximating the size of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, it is advised to use 150mg of the sample. It's suggested to use a jeweler’s scale for specimen weighing. In cases where scalp hair is not obtainable, an equivalent quantity of body hair can be used. Head hair specifically denotes scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The steps in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating the sample into the lab’s system. This step checks if the sample was correctly sealed and mailed, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry omitted by an electronic chain of custody system.
Screening consists of an initial assessment for drug usage. While Screening serves as a cost-effective measure to eliminate drug use suspicions in most samples, a positive screening needs verification to be valid in court. Samples with presumptive positives in Screening necessitate secondary confirmation.
For samples with presumptive positives during the Screening stage, additional hair is extracted from the initial sample and readied for Extraction. This step extracts drugs from hair in concentrations far lower than other methods (e.g., urine or oral fluid), which makes hair drug testing the most complex method to execute.
Confirmation of any positive screen result uses GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as warranted. The full laboratory procedure from Accessioning through Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
