Hair testing has emerged as a robust method for identifying drug and alcohol consumption. The hair strands capture biomarkers in their fibers during growth, offering a lasting record of substance use. When taken near the scalp, hair can reveal drug use for up to roughly 90 days. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches in length, with about 200 strands (similar in size to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is an optimal quantity for initial testing and validation. For EtG, additional markers, and/or testing exceeding 10 panels, a sample weighing 150mg is advisable. Using a jeweler’s scale for measurement is recommended. In the absence of scalp hair, an equivalent amount of body hair can be used. The mention of head hair pertains solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The key stages in lab processing for drug testing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step in handling a sample within a lab's system. This entails ensuring the sample's seal and shipment were intact, assigning a random LAN (Laboratory Accessioning Number), and performing any further data entry not covered by an electronic chain of custody setup.
Screening offers a preliminary assessment for substance use. Although it provides a cost-efficient method to eliminate drug use in most samples, a positive screen necessitates further verification for legal admissibility. Samples that test positive in Screening require additional confirmation.
Presumptively positive samples in Screening have more hair extracted from the original specimen for further Extraction. During this step, substances are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or saliva), highlighting the complexity of hair drug testing.
Confirmation of any positive results from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a washing process before confirmation if necessary. The entire lab protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and compliance with ISO / IEC 17025 certifications.
