Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and drug exposure by encapsulating biomarkers within the strands' fibers as they grow. Sampling hair near the scalp can offer insight into substance use over an approximate three-month period. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising about 200 hairs (comparable to a #2 pencil's diameter) closest to the scalp provides 100mg, the optimum quantity for analysis and verification. For tests like EtG add-ons or those exceeding 10 panels, 150mg of hair is preferred. It's advisable to measure the sample using a jeweler’s scale. If head hair is scarce, an equivalent amount of body hair can be gathered. When mentioning head hair, it solely refers to scalp hair, whereas body hair encompasses all other types (such as facial or axial).
Process Overview
The primary stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails entering a sample into the lab's workflow, verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data not included in an electronic custody chain.
Screening is the preliminary assessment for prohibited substances. Although it's a cost-saving method for excluding drug presence in most samples, a positive screen necessitates confirmation for legal acceptability. Samples testing presumptive positive in Screening require additional authentication.
Should a sample test presumptively positive during Screening, more hair from the collected sample is used for the Extraction phase. This phase involves extracting drugs from hair at lower concentrations compared to other techniques (e.g., urine or oral fluids), making hair drug tests more challenging to administer.
GC/MS, GC/MS/MS, or LC/MS/MS are employed for confirming positive screenings. Presumptive positives are washed before confirmation if needed. Every step from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation, and holds accreditation to ISO / IEC 17025 standards.
