Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. By encasing biomarkers within the fiber of the growing hair strand, hair offers an extended historical record of alcohol and other substances. If sampled near the scalp, it can reveal alcohol and drug usage for up to roughly three months. Hair collection is straightforward, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches from about 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, perfect for assessment and verification. For EtG, added tests, and/or examinations exceeding 10 panels, it is advised to have 150mg of the sample. We suggest using a jeweler’s scale to measure the sample weight. If scalp hair isn't accessible, an equivalent quantity of body hair can be gathered. When mentioning head hair, it pertains only to scalp hair. Body hair encompasses other types of hair (facial, axillary, etc.).
Process Overview
The laboratory process of drug test analysis comprises four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with integrating a sample into the lab's system. This step verifies proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data input missing from an electronic custody trail.
Screening serves as an initial assessment for drug presence. Although it's a cost-efficient approach to negate drug consumption in most samples, any positive results must be confirmed for legal admissibility. Samples showing presumptive positivity during Screening need a further confirmation.
For presumptive positive samples from the Screening phase, additional hair is extracted from the original specimen and processed for Extraction. This stage involves obtaining drugs from hair at much reduced concentrations compared to other methods (such as urine or saliva), which makes hair drug screening an intricate approach.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples identified as presumptive positive are cleansed ahead of confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair criteria and certified under ISO / IEC 17025 standards.
