Hair screening has emerged as an effective method for identifying substance use involving drugs and alcohol. Hair retains extended historical data by encapsulating markers within its growing strand. Gathered near the scalp, hair can reveal substance use up to nearly three months in the past. It's easy to collect, hard to tamper with, and convenient to transport.
A segment measuring 1.5 inches and roughly 200 hairs, equivalent to the width of a #2 pencil, closest to the head, supplies 100mg of hair, which is perfect for both screening and verification. For EtG, add-ons, or tests exceeding 10 panels, a sample weighing 150mg is advised. Using a jeweler's scale, we suggest weighing the sample. If scalp hair is missing, an equal volume of body hair can be used. When we say head hair, we exclusively mean scalp hair. Body hair covers all other sorts of hair (such as facial, axillary, etc.).
Process Overview
There are four crucial phases in the lab handling of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample's initial handling within a lab's framework. This phase ensures the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and fills in any missing details not covered by a digital custody system.
Screening offers an initial, fast assessment for substance misuse. While Screening is budget-friendly and can eliminate drug use in most samples, a positive finding requires confirmation for legal admissibility. Any samples with a preliminary positive result in Screening need further confirmation.
Should a sample show a likely positive in the Screening phase, extra hair is extracted from the primary sample and made ready for Extraction. Here, drugs are retrieved from hair at a significantly lower concentration than via other methods (such as urine or oral fluids), underscoring why hair drug tests are among the most challenging to conduct.
Positive findings from Screening proceed to Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes undergo washing before Confirmation, as necessary. Each lab step from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
