Hair analysis is now acknowledged as an effective method for identifying substance and alcohol misuse. Hair captures a prolonged timeline of alcohol and drug exposure by embedding biomarkers within the strands' fibers during hair formation. When sourced near the scalp, hair can reveal alcohol and drug traces for up to three months. Hair extraction is straightforward, reasonably tamper-resistant, and convenient to transport.
A 1.5-inch length from around 200 hair strands (similar in size to a #2 pencil) taken from the scalp yields approximately 100mg of hair, which is the optimal amount for screening and confirmation. For tests involving EtG, add-ons, or more than 10 panels, 150mg of the sample is advised. It's beneficial to weigh the sample using a jeweler's scale. If there's a lack of scalp hair, an equivalent portion of body hair is acceptable. By 'head hair', we specifically mean 'scalp hair'. 'Body hair' encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The lab analysis of a drug test result consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial handling in the lab's system. This step involves ensuring the sample's sealed state and proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and inputting any supplemental data not available through an electronic chain of custody.
Screening executes a preliminary check for abusive substances. Although Screening is cost-efficient for negating drug usage in most samples, a positive outcome requires confirmation for legal admissibility. Samples identified as likely positive during Screening mandate additional confirmation.
Should a sample test positive in the Screening phase, more hair is extracted from the original sample for Extraction. Here, drugs are drawn out from hair at much lower levels compared to other methods (such as urine or oral samples), making hair drug testing the most challenging to conduct.
Positive screening findings undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing initial positivity are washed before confirmation as necessary. The full lab procedure, from Accessioning to Confirmation, is audited according to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
