Hair testing is recognized as an effective approach for identifying drug and alcohol consumption. Hair strands record a prolonged history by encapsulating biological markers within the fibrous structure of the growing hair. When sourced near the scalp, hair can offer a detection window of about up to three months for alcohol and various drugs. Collecting hair is straightforward, relatively tamper-proof, and simple to transport.
A 1.5-inch segment of around 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred amount for analysis and verification. For EtG detections, supplementary checks, and/or evaluations exceeding 10 panels, a specimen of 150mg is advisable. It's recommended to measure the specimen using a jeweler’s scale. In case scalp hair isn't available, an equivalent quantity of body hair can be gathered. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other hair varieties (facial, underarm, etc.).
Process Overview
The process for laboratory drug test analysis consists of four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing step where a sample enters the lab’s workflow. This step entails confirming the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any residual data input not furnished by an automated chain of custody system.
Screening executes an initial rapid assessment for drug abuse presence. Although Screening is an economical method for excluding drug use across most samples, any positive screen requires confirmation to be court-admissible. Samples with a presumptive positive in Screening need secondary confirmation.
If presumptive positivity arises during Screening, additional hair is extracted from the initial sample for the Extraction phase. Drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thereby making hair drug testing a highly challenging methodology.
Confirmation of any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo washing before confirmation when necessary. The full laboratory procedure from Accessioning through Confirmation complies with both CAP (College of American Pathologists) Hair stipulations and ISO/IEC 17025 accreditation standards.
