Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, this offers a detection period of up to approximately three months for substances. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) taken nearest to the scalp will produce 100mg of hair, which is optimal for testing and confirmation procedures. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is suggested. Utilizing a jeweler’s scale for weighing is advised. If scalp hair is absent, a comparable amount of body hair can be substituted. The term "head hair" specifically denotes scalp hair, whereas "body hair" encompasses all other body areas like facial or axillary hair.
Process Overview
The laboratory drug testing process includes four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample first enters the lab's system. This process includes checks to ensure proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any data input not already included in an electronic chain of custody.
Screening serves as an initial quick assessment for drug presence. Though this is an economical method to negate drug usage for most samples, any positive results must be verified to be legally valid. Samples showing presumptive positives during Screening progress to a confirmatory phase.
Should a sample be tentatively positive in Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from the hair at much lower intensities than seen in other methods (such as urine or oral fluid), contributing to the complexity of hair drug screening.
The Confirmation step for any positive screening results is undertaken with GC/MS, GC/MS/MS, or LC/MS/MS techniques. Pre-confirmation, samples marked presumptive positive are cleansed as required. The full laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 criteria.
