Hair testing is now regarded as an effective means for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of growing hair, it provides an extended history of alcohol and other drug use. Sampling hair near the scalp can offer an approximate 3-month detection period for both alcohol and other substances. Collecting hair is straightforward, relatively tamper-proof, and simple to transport.
Gathering a 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) from the scalp furnishes 100mg of hair, which is the ideal quantity for both screening and confirmation. For tests involving EtG, add-ons, or those exceeding 10 panels, it's suggested to collect 150mg of hair. It is advised to measure the sample using a jeweler’s scale. In cases where scalp hair is lacking, an equivalent volume of body hair can be used instead. When mentioning head hair, it exclusively refers to scalp hair. Body hair pertains to all other varieties (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result consists of four major phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed and recorded in the laboratory’s system. This phase confirms correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any required data entry not covered by an electronic chain of custody system.
Screening is a rapid preliminary check for drugs of abuse. Although Screening offers a cost-efficient approach to rule out drug usage in most samples, any positive result must be confirmed for court admissibility. Presumptively positive samples in the Screening process require a subsequent confirmation.
Should a sample test presumptively positive at Screening, additional hair is utilized from the initial batch and readied for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations than with other approaches (e.g., urine or oral fluid), thus making hair drug screening one of the most challenging methods.
Subsequent Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory procedure, from Accessioning through Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.
