The application of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the strands of hair, it offers a comprehensive timeline of substance use. When hair is sampled near the scalp, it may reveal a drug or alcohol presence for a period of up to three months. The process of collecting hair is straightforward, less vulnerable to tampering, and easily transported.
Acquiring a sample measuring 1.5 inches, approximately 200 hair strands (about the thickness of a #2 pencil) close to the scalp, provides 100mg of hair – the standard amount for analysis. To conduct tests such as EtG, additional services, or panels exceeding ten tests, a recommendation of 150mg is advised. Using a jeweler's scale is suggested for weighing the hair sample. In instances where scalp hair is not available, an equal volume of body hair may be utilized. It's important to note that head hair references specifically scalp hair, while body hair encompasses all other hair types, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test result typically involves four steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into a lab's system. This step involves checking sample integrity, assigning a LAN (Laboratory Accessioning Number), and filling in any supplementary data that the electronic chain of custody system might lack.
Screening serves as a preliminary evaluation for drugs of abuse. It is a cost-effective method for excluding drug use in the majority of cases; however, a positive screen demands subsequent confirmation for legal admissibility. Any specimens yielding a presumptively positive result during Screening necessitate further confirmation.
Should a sample return a presumptive positive result in the Screening phase, additional hair from the original sample is readied for Extraction. At this phase, drugs are isolated from the hair at significantly lower concentrations than alternative procedures (e.g., urine or saliva), making hair drug tests among the most complex methodologies to execute.
Confirmation of any positive Screening outcomes is carried out through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
