Hair testing has earned recognition as a potent means for identifying drug and alcohol intake. Hair traps biomarkers within its fibers, offering a comprehensive history of substance use. A sample taken near the scalp can indicate usage of alcohol and other substances over a roughly three-month period. Hair is straightforward to collect, challenging to tamper with, and simple to transport.
A 1.5-inch hair sample consisting of around 200 strands, equivalent in width to a #2 pencil, offers about 100mg of hair, which is ideal for both screening and confirmation procedures. For EtG, additional tests, and panels beyond 10, a 150mg sample is advisable. It is suggested to measure the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent volume of body hair can be gathered. "Head hair" pertains exclusively to scalp hair, whereas "body hair" encompasses other hair varieties (e.g., facial, axillary).
Process Overview
The laboratory processing of drug testing results comprises four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is entered into a laboratory's system. This process confirms that the sample was correctly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number) at random, and completes any additional data entries absent from an electronic chain of custody system.
Screening entails an initial, brief drug abuse assessment. Although Screening is a cost-effective means to dismiss drug use for most samples, legal admissibility necessitates confirming any positive results. Any samples that indicate potential positivity in Screening demand further confirmation.
When a sample is tentatively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, substances are drawn from hair at significantly lower concentrations than other methods (such as urine or oral fluid), highlighting the complexity of performing hair drug screenings.
Handling any positive Screening outcomes is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicating preliminary positivity undergo washing before confirmation if needed. The entire laboratory process from Accessioning to Confirmation adheres to scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
