Hair analysis is now regarded as a robust method for discovering drug and alcohol consumption. Hair captures a long-term record of drugs and alcohol by embedding biomarkers within the strands as they grow. When samples are collected near the scalp, they can disclose up to a quarter of a year's worth of alcohol and drug history. Hair is easy to gather, fairly resistant to tampering, and simple to transport.
A hair sample measuring 1.5 inches from about 200 strands (roughly the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for both screening and confirmation tests. For testing EtG, add-ons, or tests beyond 10 panels, 150mg is advised. Using a jeweler’s scale is recommended for weighing the sample. In cases where scalp hair isn't available, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair (facial, axillary, etc.).
Process Overview
The laboratory steps for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab system. This stage involves confirming the sample's proper seal and shipment, assigning it a random LAN (Laboratory Accessioning Number), and finishing any other data input that the electronic chain of custody system does not cover.
Screening serves as a preliminary assessment for substances of abuse. Although it is a cost-saving method for dismissing drug use in most samples, a positive screen must be verified to be legally valid. Samples testing positive in Screening require further confirmation.
If a sample tests positive in Screening, additional hair is taken from the original sample for Extraction. Drugs are extracted at significantly lower concentrations than seen in other tests (like urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Confirmation for a positive screen is done via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all positive samples are cleansed as necessary. The procedural flow from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.
