Recognized as an effective resource, hair testing is utilized for identifying drug and alcohol consumption. This method offers a comprehensive timeline of drug markers preserved within the strands of hair as they grow. When collected from just above the scalp, hair samples can reveal evidence of alcohol and drug use for up to a three-month timeframe. The collection process is straightforward, tampering is more challenging, and shipping is simple.
A sample measuring 1.5 inches from around 200 hair strands (approximately the size of a #2 pencil) situated near the scalp yields 100mg of hair, which is the optimal quantity for both screening and definitive testing. For EtG, supplementary tests, or those exceeding 10 panels, it's advisable to collect 150mg of hair. Using a jeweler’s scale for weighing the sample is recommended. If it's not possible to obtain scalp hair, a comparable amount of body hair may be collected. By 'head hair,' we mean only scalp hair; 'body hair' pertains to other hair types (like facial, axillary, etc.).
Process Overview
The core steps in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is entered into the laboratory's system. This step entails checking whether the sample was sealed and shipped correctly, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data tasks not managed electronically by a chain of custody system.
Screening offers an initial assessment for drug presence. This quick-check method is a low-cost approach to eliminate drug use in most samples; however, confirmed positivity is necessary for legal proceedings. All samples indicating potential positivity during Screening require additional confirmation.
In instances where Screening suggests a positive result, further hair is taken from the sample for Extraction. This phase involves extracting drugs at lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most intricate method.
Confirmation of positive screenings occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Preceding confirmation, samples showing potential positivity undergo thorough washing. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 certification.
