Hair testing is regarded as a robust method for detecting drug and alcohol consumption. Such testing offers an extended history of substance use by encapsulating biomarkers within the growing hair's fibers. When obtained near the scalp, hair samples can demonstrate a detection period of up to roughly 3 months for substances. Hair collection is straightforward, hard to tamper with, and easily transported.
A 1.5-inch segment containing about 200 strands of hair (approximately the width of a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimal sample for both screening and confirmation processes. For EtG, additional tests, and/or analyses beyond 10 panels, 150mg of the sample is advised. It is beneficial to gauge the sample using a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair might be used. References to head hair pertain exclusively to scalp hair. Body hair includes any other kinds of hair (facial, axillary, etc.).
Process Overview
The principal phases in the laboratory processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab's system. This stage ensures the sample is correctly sealed and transported, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any missing data entry not supplied via an electronic chain of custody.
Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening efficiently excludes substance use in most cases, a positive screen requires confirmation for admissibility in legal settings. Samples that are seemingly positive in Screening require further confirmation.
Samples with a presumptive positive outcome during the Screening are further processed by retrieving additional hair from the original specimen for Extraction. At this phase, drugs are extracted from the hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug screening the most challenging test to conduct.
Positive results from Screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleaned before confirmation when necessary. The laboratory procedure from Accessioning to Confirmation undergoes supervision under the CAP (College of American Pathologists) Hair criteria and alignment with ISO / IEC 17025 standards.
