Hair evaluations are now recognized as an effective means for identifying substance and alcohol consumption. Hair provides an extended period history of alcohol and drugs by capturing biomarkers within the hair shaft's fibers. When hair is obtained near the scalp, it can supply approximately a 3-month detection duration for alcohol and drugs. The collection of hair is straightforward, challenging to tamper with, and simple to send.
A 1.5-inch segment consisting of about 200 hair strands (roughly the circumference of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair is not available, a comparable amount of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The workflow in the lab processing of a drug test outcome comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial processing phase where a sample is entered into a lab's system. This includes validating that the sample was sealed correctly and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional information entry not covered by an electronic chain of custody system.
Screening involves a preliminary evaluation for drug abuse. While Screening is an economical method to exclude drug use in most samples, a positive result requires Confirmation for legal acceptance. Samples that test presumptively positive in Screening must undergo secondary Confirmation.
If a sample tests presumptively positive during Screening, more hair is extracted from the initial sample for the Extraction phase. In this phase, hair drugs are extracted at substantially lower concentrations than in other procedures (e.g., urine or oral fluid), making hair drug screening the most complex technique to execute.
Confirmation of any positive Screening outcome is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo washing before Confirmation as necessary. The complete laboratory procedure from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
