Hair analysis is recognized as a potent method for identifying drug and alcohol consumption. The hair gives an extended historical account of alcohol and drug use by locking biomarkers within the fibers of the hair that is growing. When taken near the scalp, it can offer roughly a 3-month detection span for both alcohol and drugs. The collection process is straightforward, relatively resistant to tampering, and easy to transport.
A sample that is 1.5 inches in length, comprising around 200 strands near the scalp, yields 100mg of hair, which is the preferred quantity for screening and confirmation purposes. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is recommended to weigh the sample using a jeweler's scale. If scalp hair is inaccessible, a comparable amount of body hair can be gathered. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (like facial, axillary, etc.).
Process Overview
There are four primary phases in the laboratory processing of hair drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into the laboratory’s system, which includes ensuring the sample’s proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and performing any extra data entry not supplied via an electronic chain of custody system.
Screening comprises a brief preliminary check for drugs of abuse. Although it's a cost-effective way to exclude drug use with most samples, a positive screen needs verification for court admissibility. Any samples with a presumptive positive result in Screening necessitate further confirmation.
If a sample shows a presumptive positive result during the Screening phase, additional hair is taken from the original specimen for Extraction. In this step, drugs are drawn from hair at significantly lower concentrations than other methods (such as urine or saliva), contributing to the complexity of hair drug screening.
Any positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives are cleansed prior to confirmation if necessary. Each step of the laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation along with accreditation to ISO / IEC 17025 standards.
