Hair testing is increasingly recognized as a robust method for identifying drug and alcohol usage. It offers an extensive timeline of substance intake by capturing biomarkers in the fibers of hair that is actively growing. When cut near the scalp, hair can reveal a detection timeline of up to about 90 days for alcohol and other drugs. This method is easy to perform, relatively resistant to tampering, and simple to transport.
An optimal sample involves a 1.5-inch length of approximately 200 strands (comparable to the thickness of a #2 pencil) close to the scalp, providing 100mg of hair, which is suitable for both screening and confirmation tests. For analyses like EtG or those exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler's scale for specimen weighing. If scalp hair isn't present, a comparable amount of body hair can be gathered. References to head hair specifically mean scalp hair, while body hair refers to any non-scalp hair (facial, underarm, etc.).
Process Overview
The laboratory processing of drug test results is composed of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into a lab's system. This stage involves checking that the sample's seal and shipping were correctly executed, generating a unique LAN (Laboratory Accessioning Number), and completing any data inputs not covered by a digital chain of custody system.
Screening carries out an initial rapid assessment for the presence of drugs. Though Screening is an economical method for negating drug use in numerous samples, a positive screening must be verified for legal acceptability. Samples identified as preliminarily positive in Screening must undergo additional confirmation.
If a specimen is deemed preliminarily positive at the Screening phase, additional hair is extracted from the original sample for the Extraction process. This is the step where drugs are removed from the hair at concentrations lower than seen in other methods (e.g., urine or saliva), which is why hair drug tests are the most complex to conduct.
Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples identified as preliminarily positive undergo washing before confirmation if necessary. The entirety of the lab process, from Accessioning through Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
