Hair testing is now recognized as a significant method for identifying drug and alcohol consumption. Hair captures a long-term timeline of alcohol and drug presence by embedding biomarkers within the hair's developing strands. When collected near the scalp, hair can offer nearly a three-month detection period for alcohol and other substances. Hair collection is straightforward, somewhat challenging to tamper with, and convenient to transport.
A sample of 1.5 inches, comprising about 200 hair strands (roughly the thickness of a #2 pencil) near the scalp, yields 100mg of hair, the perfect quantity for both screening and confirmation. For EtG add-ons and/or tests exceeding 10 panels, a 150mg specimen is recommended. It is advised to weigh the specimen using a jeweler's scale. If scalp hair is unavailable, a like amount of body hair may be used. The term "head hair" specifically denotes scalp hair. "Body hair" refers to all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This process verifies that the sample was appropriately sealed and dispatched, assigns it a random LAN (Laboratory Accessioning Number), and fulfills any necessary data entries not included by an electronic chain of custody system.
Screening is a preliminary rapid analysis for substances of abuse. While it provides a cost-efficient method to exclude drug use in most samples, a positive screen must be verified to be valid in a legal context. Samples that are initially positive in Screening require subsequent confirmation.
If Screening indicates a presumptive positivity, more hair from the sample is utilized for Extraction. During Extraction, drugs are isolated from hair at concentrations far lower than other methods (e.g., urine or oral fluid), hence hair drug screening is acknowledged as one of the most challenging methodologies.
Any positive Screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed before confirmation as needed. The complete process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
