Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The fibers of growing hair strands trap biomarkers, offering an extended record of substance use. When sampled close to the scalp, hair can reveal usage of alcohol and drugs for a period of up to roughly three months. Hair collection is straightforward, relatively resistant to tampering, and easily shipped.
A 1.5-inch hair sample containing around 200 strands (similar in size to a #2 pencil) gathered near the scalp provides an approximate weight of 100mg, ideal for screening and confirmation processes. For EtG analyses, additional testing, or examinations that exceed 10 panels, a specimen weight of 150mg is advisable. It's suggested to measure the sample using a jeweler’s scale. In instances where scalp hair is not available, a similar quantity of body hair may be used. The term head hair specifically refers to scalp hair, whereas body hair includes all other hair types (such as facial or axillary).
Process Overview
The drug test result laboratory process consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory system. This step includes ensuring that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry that was not included by an electronic chain of custody system.
Screening serves as a preliminary technique to detect drug usage. While Screening is an economical approach to eliminate drug use in most samples, a positive result requires confirmation for legal validity. Any samples deemed presumptively positive in Screening need subsequent confirmation.
In cases where Screening indicates a presumptive positive, additional hair is extracted from the original sample for further preparation in the Extraction process. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis a particularly challenging methodology.
Confirmation of positive Screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as required before confirmation. The entire laboratory procedure, from Accessioning through Confirmation, is conducted in compliance with the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
