Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol usage. Hair offers a long-lasting record of substances by sequestering biomarkers in the strands during growth. When cut near the scalp, hair can indicate alcohol and drug presence over a time span of up to about three months. Collecting hair is straightforward, not easily manipulated, and convenient to transport.
A sample of 1.5 inches, consisting of roughly 200 hair strands (similar in size to a #2 pencil), obtained from the scalp, yields 100mg, which is the optimal amount for both screening and confirmation processes. For EtG, extended panels, or tests exceeding 10 panels, a sample size of 150mg is advisable. It's recommended to weigh the sample with a jeweler's scale. If head hair isn't an option, a similar quantity of body hair can be used. References to head hair indicate scalp hair exclusively. Body hair encompasses all other types (e.g., facial, underarm).
Process Overview
The primary steps in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the lab’s system, ensuring it was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic chain of custody.
Screening provides an initial quick assessment for drug presence. Although Screening is a cost-effective method for excluding drug use in the majority of samples, any positive findings must be followed up with confirmation to hold up in legal settings. Samples testing positive during Screening need subsequent verification.
When a sample tests positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or saliva), making hair drug testing one of the more challenging methods to perform.
Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed before confirmation as necessary. The laboratory process from Accessioning to Confirmation is vetted under both CAP (College of American Pathologists) standards for Hair and accreditation under ISO/IEC 17025 standards.
