The use of hair analysis has become a significant approach in identifying drug and alcohol consumption. Hair retains a prolonged record of substances, capturing biomarkers within the strands of growing hair. When taken near the scalp, hair can reveal substance use for up to three months for drugs and alcohol. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp will provide 100mg of hair, the preferred quantity for analysis and verification. For EtG, additional screenings, or panels exceeding 10 types, a sample of 150mg is advisable. It is suggested to weigh the sample using a jeweler’s scale. In cases where scalp hair is lacking, a similar quantity of body hair can be used. Scalp hair specifically refers to head hair, while body hair includes all other types like facial or axillary hair.
Process Overview
The laboratory procedure for processing a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase of integrating a sample into a lab's system. This step ensures the sample was appropriately sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and manages any additional data inputs absent from an electronic chain of custody system.
Screening serves as an initial assessment for substances of abuse. Although Screening is a budget-friendly method for ruling out drug usage across most specimens, a positive result must be verified for legal validity. Presumptive positives from Screening necessitate further confirmation.
Should a sample display a presumptive positive during Screening, additional hair is extracted from the initial sample for Extraction. During Extraction, substances are separated at much lower levels than other testing techniques (such as urine or saliva), highlighting the complexity of hair drug testing.
Confirmation of any screening positive is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives undergo washing as necessary before Confirmation. The complete laboratory workflow, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
