Hair analysis is increasingly recognized as an effective method for detecting the consumption of drugs and alcohol. Hair strands capture biomarkers within their fibers, thus providing a comprehensive timeline of substance usage. When hair is collected near the scalp, it can reveal drug and alcohol use for a time frame of up to three months. Hair collection is straightforward, challenging to tamper with, and uncomplicated to transport.
A sample measuring 1.5 inches made up of approximately 200 hair strands (akin to the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation tests. For EtG, additional tests, or panels exceeding 10 in number, 150mg of the specimen is suggested. We advise using a jeweler’s scale to measure the specimen's weight. In cases where scalp hair is not available, an equivalent quantity of body hair can be utilized. References to head hair pertain exclusively to scalp hair, whereas body hair encompasses all other forms of hair (such as facial and axillary hair).
Process Overview
The laboratory analysis of drug test results consists of four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning serves as the initial step in processing a sample within a laboratory’s system. It involves confirming that the sample was properly sealed and shipped, generating a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry that was not covered by an electronic chain of custody system.
Screening is a preliminary assessment for substance abuse. Although Screening efficiently eliminates drug use on most samples, a positive result requires confirmation to hold up in legal settings. Any samples that yield a presumptive positive during Screening must undergo a subsequent confirmation.
In the event a sample tests presumptively positive during the Screening stage, additional hair is extracted from the initial specimen for the Extraction phase. During Extraction, drugs are isolated from the hair at a lower concentration compared to other methods (e.g., urine or saliva), making hair drug testing the most challenging methodology to conduct.
Confirmation for any presumptive positive result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples that are positive presumptively are cleansed before confirmation, as needed. The entire processing sequence, from Accessioning to Confirmation, is reviewed in accordance with both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
