Hair analysis has become recognized as a robust method for identifying alcohol and drug consumption. Hair retains a prolonged record of alcohol and other substances by capturing biomarkers within the structures of growing hair. When acquired near the scalp, hair can offer up to a roughly 3-month period for detecting alcohol and other substances. Hair is easy to gather, moderately tough to tamper with, and straightforward to send.
A 1.5-inch section comprising about 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample for screening and verification. For EtG, supplements, and/or assessments exceeding 10 panels, 150mg of the sample is advised. We advocate for weighing the sample using a jeweler’s scale. If scalp hair is not obtainable, a comparable quantity of body hair can be gathered. When mentioning head hair, this refers strictly to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four core steps in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial entry of a sample into a lab’s database, confirming the sample was sealed and transported correctly, assigning a randomized LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening entails a preliminary rapid test for drugs of misuse. Although Screening is a budget-friendly method to rule out drug use in the bulk of samples, a positive screen must be verified for court acceptability. Samples testing presumptively positive in Screening necessitate secondary confirmation.
If a sample presents as presumptively positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. In this phase, substances are isolated from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), rendering hair drug analysis the most challenging technique to execute.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to verification as necessary. The complete laboratory sequence from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
