Seen as a significant method for identifying substance and alcohol consumption, hair testing is a favored approach. Hair can offer a comprehensive record of substances like alcohol by embedding markers in the strands as the hair grows. When taken near the scalp, hair can reveal exposure to substances over a span of roughly three months. Collecting hair is straightforward, somewhat resistant to tampering, and easy to dispatch.
A 1.5-inch section of approximately 200 hairs (similar to the thickness of a #2 pencil) closest to the scalp yields 100mg, which is the preferred amount for screening and confirmation processes. For EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale is recommended to weigh the sample. Should scalp hair be unavailable, a similar amount of body hair can be used. When we mention head hair, we focus on scalp hair. Body hair encompasses any other types of hair (such as facial, underarm, etc.).
Process Overview
The laboratory workflow for processing a drug testing outcome involves the crucial stages of Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the beginning phase of integrating a sample into the lab’s database. This phase ensures that the sample is appropriately sealed and shipped, involves assigning it a unique LAN (Laboratory Accessioning Number), and includes any required data entry not handled by an electronic chain of custody mechanism.
Screening incorporates a preliminary assessment for substances. Although Screening is a cost-efficient technique for excluding drug consumption in most samples, a positive screen mandates verification to hold up in legal proceedings. Any samples that test presumptively positive during Screening require follow-up confirmation.
In cases where a sample tests positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. During this step, substances are drawn from hair at a significantly lower concentration in comparison to other techniques (e.g., urine or saliva), highlighting the complexity of hair drug screening.
Verification of any positive initial screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Any presumptively positive samples undergo a cleansing process before confirmation as needed. The complete process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
