Hair analysis is increasingly recognized as an effective means of detecting drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the strands as they grow. When hair is collected near the scalp, it can offer nearly a 3-month period for identifying alcohol and drug usage. The collection process is straightforward, it is relatively secure against tampering, and shipping is convenient.
A sample spanning 1.5 inches and consisting of roughly 200 hair strands (comparable to a #2 pencil in thickness) near the scalp yields around 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or evaluations exceeding 10 panels, a specimen weighing 150mg is preferable. It is advisable to measure the sample with a jeweler’s scale. If there’s no scalp hair, an equivalent volume of body hair is acceptable. “Head hair†indicates only scalp hair, while “body hair†encompasses all other varieties (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test includes four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step in processing a sample into the lab system, involving checks to ensure the sample was properly sealed and sent, assignment of a random LAN (Laboratory Accessioning Number), and completion of any missing data entry that isn’t part of an electronic chain of custody system.
Screening serves as an initial rapid check for substance abuse. Although cost-effective for ruling out drug usage in most samples, a positive finding during Screening necessitates confirmation for legal acceptability. Samples that test presumptively positive at this stage require further confirmation.
In the Screening phase, if a sample returns a presumptively positive result, further hair from the original sample is used for Extraction. During Extraction, drugs are retrieved from hair at much lower concentrations compared to other methods (such as urine or oral fluid), contributing to hair drug testing's complexity.
Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation adheres both to the CAP (College of American Pathologists) Hair criteria and the accreditation standards of ISO / IEC 17025.
