The utilization of hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a chronological record of alcohol and drug intake by embedding biomarkers in the fibers of the hair as it grows. When obtained near the scalp, hair provides an approximate three-month window for detecting alcohol and drugs. The collection process for hair is straightforward, somewhat resistant to tampering, and convenient for shipping.
A 1.5-inch-long hair sample encompassing about 200 strands (roughly equating to the size of a standard #2 pencil) collected nearest to the scalp yields 100mg, which is optimal for screening and verification. For tests like EtG additions or those exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale to weigh the sample is recommended. In cases where scalp hair is absent, an equivalent amount of body hair can be collected. "Head hair" refers exclusively to scalp hair, whereas "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory process for generating a drug test result comprises four crucial steps, namely Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning of processing a sample within a lab’s framework. This phase ensures the sample’s seal and shipping integrity, assigns a random Laboratory Accessioning Number (LAN), and fills in any missing data not captured by an electronic chain of custody system.
Screening serves as an initial assessment for controlled substances. While Screening is a budget-friendly method for excluding drug use on the bulk of samples, any positive Screening outcome requires confirmation to be court-admissible. Presumptively positive samples during Screening undergo further confirmation.
Should a sample show a presumptive positive result in Screening, additional hair is extracted from the original batch and readied for Extraction. This phase involves retrieving drugs from hair at much lower concentrations than in alternative approaches (e.g., urine or oral fluid), explaining why hair drug testing represents one of the more technically challenging methodologies.
Confirmation of any Screening positive results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives undergo a wash prior to confirmation when necessary. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
