Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair provides an extended record of alcohol and drug exposure by capturing biomarkers within the fibers of the hair shaft as it grows. When harvested near the scalp, hair can reveal substance use over roughly a 3-month period. It is straightforward to collect, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches with approximately 200 strands, akin to a #2 pencil, near the scalp will yield 100mg of hair, the preferred amount for analysis and verification. For EtG, additional panels, and/or tests exceeding 10 panels, 150mg of hair is advised. We suggest using a jeweler’s scale for accuracy. If scalp hair is not present, a similar quantity of body hair may be gathered. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The drug testing procedure at a laboratory involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a laboratory. This includes ensuring the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional required data entry not captured by an electronic chain of custody record.
Screening provides an initial assessment for drugs of abuse. While it is a cost-efficient method to dismiss drug use in most samples, a positive result from Screening requires confirmation for legal proceedings. Samples appearing positive in Screening must undergo a secondary confirmation.
If a sample tests positive in the Screening phase, more hair from the original sample is used for Extraction. Here, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging method to conduct.
Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as necessary before confirmation. The entire laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
