Hair analysis has emerged as an important method for detecting the use of drugs and alcohol. Hair captures a long-term record of substances through biomarkers embedded in the expanding hair strand. When taken near the scalp, hair can offer nearly a 3-month period for detecting alcohol and other substances. Hair is easy to gather, moderately challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches with around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample on a jeweler's scale. If scalp hair isn't available, a comparable quantity of body hair might be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The primary steps in the lab process of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample into a lab’s system. This step includes ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not offered by an electronic chain of custody system.
Screening is a preliminary rapid check for drugs of abuse. While it is a cost-efficient way to eliminate drug usage in most samples, a positive screen must be confirmed for it to be legally admissible. Presumptive positive samples from Screening need a secondary confirmation.
In the event of a presumptively positive sample at the Screening phase, more hair is extracted from the initial sample and readied for Extraction. Here, drugs are extracted at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.
Confirmation of any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
