Hair analysis has emerged as an effective method for identifying the consumption of substances. It offers an extended timeline by effectively preserving indicators within the structure of the hair as it grows. When cut close to the scalp, hair can reveal insights into substance use spanning roughly three months. It's straightforward to collect, challenging to tamper with, and convenient for transportation.
Obtaining a 1.5-inch sample containing approximately 200 hairs (comparable to the diameter of a #2 pencil) ensures a 100mg collection, which is optimal for both initial screening and subsequent validation. For EtG tests, additional panels, and comprehensive tests beyond 10 panels, 150mg is advised. We propose using a jeweler’s scale for precise measurement. In cases where scalp hair is unavailable, collection of a similar amount of body hair is acceptable. References to head hair signify scalp hair alone, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The procedural flow for processing a drug test in a lab comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the sample’s entry into a laboratory’s system. This process ensures the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding information not provided by an electronic chain of custody system.
Screening acts as a preliminary assessment for substances of abuse. Though cost-efficient for excluding substance use in most samples, any positive findings here must be verified for legal acceptability. Positives from Screening need further confirmation.
Should a sample test positive in Screening, additional hair from the initial sample is utilized for Extraction. Here, drugs are extracted from hair at a notably lower concentration than in methods such as urine or oral fluid testing, underscoring the complexity of hair drug testing.
Positive results necessitate Confirmation via techniques like GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptive positives undergo cleaning as necessary. The entire lab process, from Accessioning through to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 standards.
