Hair screening is now recognized as an essential method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other substances by embedding biomarkers in the strands as they grow. When sourced near the scalp, hair can offer a detection span of up to roughly 90 days for alcohol and other drugs. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.
A 1.5-inch collection of around 200 hair strands (similar to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, an ideal sample for testing purposes. For EtG, additional analyses, or assessments beyond 10 panels, 150mg of the sample is advised. It is advisable to utilize a jeweler’s scale for specimen weighing. If head hair is not available, an equivalent volume of body hair may be used. "Head hair" refers only to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab handling of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the sample's processing within the lab system. This phase involves confirming the sample’s proper sealing and delivery, allocating a random LAN (Laboratory Accessioning Number), and completing any missing data entry that an electronic chain of custody system doesn't provide.
In the Screening step, an initial rapid evaluation for illegal drugs is conducted. Although Screening efficiently eliminates drug use for most samples, a positive result requires further verification to be legal in court. Any samples indicating a presumptive positive during Screening demand a secondary confirmation.
If a sample displays a presumptive positive at the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are separated from hair at lower concentrations compared to other methods (such as urine or saliva), making hair drug testing a challenging procedure.
GC/MS, GC/MS/MS, or LC/MS/MS are used for Confirming any positive screening outcome. All presumptive positive samples undergo washing prior to confirmation as required. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
