Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands of hair as they grow. When sourced from near the scalp, hair can show alcohol and drug presence for up to about three months. Collecting hair is straightforward, relatively tamper-resistant, and convenient for shipment.
A 1.5-inch segment of roughly 200 hair strands (about the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is an optimal sample size for testing and verification. For EtG, additional tests, or panels beyond 10, 150mg of the sample is suggested. Using a jeweler's scale to weigh the sample is advised. If scalp hair isn't available, an equivalent amount of body hair is acceptable. References to head hair mean scalp hair specifically. Body hair includes other hair categories (facial, axillary, and so on).
Process Overview
The four core stages in laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary handling of a sample in a lab's framework. This process involves ensuring the sample is properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody framework.
Screening entails a preliminary rapid assessment for prohibited substances. Although Screening serves as an economical approach to eliminate drug intake on most samples, a positive indication requires verification to be permissible in legal settings. Samples indicating a presumptive positive in Screening necessitate a further confirmation process.
Should a sample suggestive of positivity in Screening, additional hair is taken from the initial sample and prepped for Extraction. This process extracts drugs from hair at a much lesser concentration than alternative techniques (such as urine or oral fluids), which contributes to the complexity of performing hair drug screening.
Verification of any positive Screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed before confirmation if needed. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair criteria and the certification to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often named "hair follicle tests", the analysis assesses the hair strand itself and not the follicle beneath the scalp.
