Hair testing has evolved as an effective means to identify drug and alcohol consumption. Hair captures a prolonged history of drugs and alcohol by holding biomarkers within the fibers of its growing strands. When collected near the scalp, hair offers an approximate detection period of three months for both alcohol and drugs. The collection process is straightforward, comparatively hard to tamper with, and convenient to transport.
A hair sample measuring 1.5 inches from around 200 strands (equivalent to a #2 pencil) closest to the scalp will yield 100mg, which is the optimal amount for both screening and confirmation. For EtG, additional panels, and tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to determine the weight with a jeweler's scale. If scalp hair is unattainable, an equivalent quantity of body hair can be gathered. Head hair specifically refers to scalp hair, whereas body hair encompasses other types such as facial or axillary hair.
Process Overview
The primary phases in the lab-based drug testing process are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to initially introducing the sample into a lab's network. This phase verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes necessary data entry unless provided via an electronic chain of custody system.
Screening functions as an initial rapid assessment for drugs of abuse. While Screening is an economical method to dismiss drug usage in most samples, a positive result requires confirmation for court admissibility. Any samples indicated as presumptively positive in Screening necessitate secondary confirmation.
If a sample is indicated as presumptively positive during Screening, more hair is extracted from the original specimen for Preparation in Extraction. Here, drugs are extracted from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug testing a more challenging methodology.
Confirmation of any positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples undergo washing before Confirmation as required. The comprehensive lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
