Hair analysis has emerged as a significant method for identifying substance use involving drugs and alcohol. By capturing biomarkers within the strands, hair retains a comprehensive record of substance usage over an extended period. When gathered near the scalp, hair can reveal drug and alcohol use over a period of up to three months. It is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (similar in size to a #2 pencil) taken nearest to the scalp, will yield 100mg, which is optimal for conducting screening and confirmation. For tests including EtG or those with more than 10 panels, a specimen weighing 150mg is advisable. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair not be available, an equivalent quantity of body hair may be utilized. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
The drug testing procedure in a laboratory is comprised of four essential steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory's system, ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any outstanding data entry not covered by an electronic chain of custody system.
Screening provides an initial, rapid assessment for drugs of abuse. Although Screening is an economical approach to negate drug usage in the majority of samples, a positive outcome necessitates confirmation to be legally acceptable. Samples detected as presumptively positive in Screening require further confirmation.
In the event of a presumptive positive in Screening, additional hair is taken from the original sample and readied for Extraction. Drugs are extracted from the hair at a substantially lower concentration than other techniques (such as urine or oral fluid), signifying that hair drug testing is one of the most complex methodologies.
Confirmation of any positive screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples marked as presumptive positive are cleansed before confirmation, if necessary. The entirety of the laboratory process, from Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
