Hair testing has become recognized as an effective means for identifying drug and alcohol consumption. Hair captures long-standing information of alcohol and other substances by entrapping biomarkers in the strands of hair as it grows. When gathered near the scalp, hair can offer a detection window for alcohol and drugs extending up to roughly 3 months. Hair is effortless to collect, challenging to tamper with, and simple to send.
A 1.5-inch portion of nearly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the perfect sample for analysis and verification. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. We advise weighing the hair on a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair can be used. When we talk about head hair, we specifically mean scalp hair. Body hair implies any other type of hair (facial, axillary, etc.).
Process Overview
The primary four steps in the lab examination of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial introduction of a specimen into a lab’s framework. This entails confirming that the specimen was appropriately sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and executing any additional documentation not accommodated by an electronic chain of custody system.
Screening incorporates an initial rapid assessment for substance misuse. While it provides a cost-effective procedure to dismiss drug use in the majority of cases, a positive outcome from Screening needs validation to be legally defensible. Any samples that yield a presumptive positive in Screening must undergo a secondary verification.
If a sample shows a presumptive positive within the Screening phase, more hair is extracted from the initial sample and is set for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than those in other techniques (e.g., urine or oral fluid), making hair drug testing the most intricate method to execute.
Validation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positive results are cleansed before confirmation as necessary. The full lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair category and compliance with ISO/IEC 17025 standards.
