Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains evidence of alcohol and other substance use over a long period by capturing markers in the strands of hair as they grow. When taken close to the scalp, hair can offer up to a three-month detection period for alcohol and drugs. It is easy to collect, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (about the thickness of a #2 pencil), close to the scalp yields 100mg, which is ideal for testing and verification. For EtG, add-ons, or tests exceeding ten panels, 150mg of hair is suggested. It is advisable to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent amount of body hair can be used. "Head hair" indicates scalp hair, whereas "body hair" includes other types like facial and axillary hair.
Process Overview
The drug test result processing involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of integrating a sample into a laboratory system. It includes ensuring the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic custody chain.
Screening is a preliminary test for drugs of abuse. While Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be confirmed for court acceptance. Any samples that are tentatively positive during Screening need further confirmation.
If a sample is tentatively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. Drugs are extracted at significantly lower concentrations from hair than from other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples assumed positive are cleansed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is checked under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 standards.
