Hair analysis is increasingly recognized as an essential method for identifying substance use. Hair can offer a comprehensive record of alcohol and drug intake by embedding biomarkers within the strands as they grow. When collected near the scalp, it can provide a detection span of up to three months for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and convenient to transport.
Collect a 1.5-inch segment of around 200 hair strands (similar to a #2 pencil diameter) closest to the scalp to achieve a 100mg hair sample, which is optimal for both screening and confirmation procedures. For EtG, extra tests, or beyond a 10-panel test, a 150mg sample is suggested. It is advisable to use a jeweler's scale to weigh the sample. If scalp hair is not an option, the equivalent quantity of body hair can be used. Scalp hair refers specifically to the hair on the head, while body hair includes all other types such as facial and axillary hair.
Process Overview
The laboratory analysis of a drug test result is comprised of four primary processes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where the sample is logged into the lab's system. This involves confirming that the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entries not covered by an electronic chain of custody.
Screening is a preliminary assessment to check for drug abuse. While it's a cost-efficient method to identify drug usage in most samples, any positive screen requires confirmation for legal admissibility. Any samples that test presumptively positive during Screening need further confirmation.
If a sample has a presumptive positive result in Screening, additional hair is extracted from the primary specimen for the Extraction phase. During this phase, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or saliva), making hair drug screening the most challenging technique.
For confirming a positive screening result, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. All samples presumed positive are cleansed before confirmation if necessary. The entire laboratory workflow from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair standards and is accredited to ISO / IEC 17025 standards.
