Hair testing is recognized as an effective means for spotting drug and alcohol usage. Hair captures a prolonged history of substance use by securing biomarkers within the expanding hair strand. When procured near the scalp, hair offers about a 3-month window for detecting drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and convenient for shipping.
A hair sample of 1.5 inches containing approximately 200 strands (roughly the thickness of a #2 pencil) near the scalp will yield 100mg, the optimal amount for both screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, 150mg is advised. It's best to use a jeweler's scale for weighing. If scalp hair isn't obtainable, a similar amount of body hair can be used. "Head hair" exclusively indicates scalp hair, while "body hair" includes all other hair varieties (e.g., facial, axillary).
Process Overview
The core steps in a lab’s drug test result processing include Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed within a laboratory’s framework. This incorporates confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data not supplied by an electronic chain of custody.
Screening is an initial swift check for substances of abuse. Although cost-effective for excluding drug usage in most samples, a positive Screening requires confirmation to be plausible in court. Samples suggesting positivity in Screening mandate secondary confirmation.
Should a sample reflect positive from Screening, additional hair is extracted from the original sample for Extraction. This phase involves extracting drugs from hair at a considerably lower concentration than alternative methodologies (such as urine or oral fluid), making hair drug screening notably challenging.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples reflecting presumptive positivity are washed pre-confirmation as needed. The lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
