Hair testing is increasingly regarded as a potent means for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the strands of hair as they grow. When sampled near the scalp, it can reveal usage of alcohol and drugs over an approximate three-month period. Collecting hair is straightforward, challenging to tamper with, and conveniently transportable.
A 1.5-inch segment containing about 200 hairs (comparable to the girth of a #2 pencil) nearest to the scalp delivers close to 100mg, the optimal sample for testing and verification. For EtG, additions, and/or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair is insufficient, a similar weight of body hair can be substituted. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails introducing the sample into the laboratory’s system initially. This step involves confirming the sample’s proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and performing any remaining data entry missing from an electronic chain of custody system.
Screening involves a preliminary rapid assessment for potential drug abuse. While Screening is a cost-effective method to rule out drug use for most samples, a confirmed positive screen is necessary for legal validity. All presumed positive samples in Screening require additional confirmation.
When a sample is presumed positive in the Screening phase, further hair is extracted from the initial sample and prepped for Extraction. During Extraction, the concentration of drugs is extracted from hair at significantly lower levels than other methodologies (e.g., urine or oral fluid), which explains why hair drug screening is the most demanding methodology to execute.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples undergo washing prior to confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, is audited under the CAP (College of American Pathologists) Hair program and accredited per ISO / IEC 17025 standards.
