Hair testing is now widely recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of substance use by capturing biomarkers within the hair strand's fibers. When collected near the scalp, it can provide an approximate 3-month detection period for alcohol and drugs. The collection process is straightforward, the sample is relatively challenging to tamper with, and it is easily transported.
A 1.5-inch hair sample consisting of roughly 200 strands (around the thickness of a #2 pencil) collected nearest to the scalp provides 100mg of hair, the ideal amount for analysis and verification. For EtG, add-ons, and/or tests beyond 10 panels, a specimen amount of 150mg is advisable. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair is absent, an equivalent volume of body hair may be collected. When we mention head hair, we mean only scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The essential steps in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory’s database, ensuring the sample has been properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not furnished by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for drugs of abuse. Though Screening is an economical method to eliminate drug usage in most samples, a positive screen must be validated to be permissible in a legal setting. Any samples provisionally positive in Screening necessitate further confirmation.
Should a sample be provisionally positive during the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. In this stage, drugs are obtained from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), rendering hair drug screening one of the most challenging methodologies to conduct.
Confirmation of a positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All provisionally positive samples are cleansed before confirmation as required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
