Hair testing is recognized as an effective method for identifying drug and alcohol usage. It offers a comprehensive overview of drug consumption over time by embedding biological markers within the strands of hair as they develop. When collected near the scalp, this method can reveal drug and alcohol use over a span of approximately three months. Collecting hair is straightforward, relatively tamper-resistant, and convenient for shipping.
Gathering a 1.5-inch section of roughly 200 hair strands (equivalent to the size of a #2 pencil) nearest to the scalp yields about 100mg of hair, which is optimal for testing and validation. For EtG, additional tests, and panels exceeding ten, a specimen weighing 150mg is advisable. It’s best to measure the sample’s weight using a jeweler's scale. Should scalp hair be unavailable, a similar quantity of body hair can be used. References to head hair specify scalp hair only, whereas body hair includes other types such as facial or axillary hair.
Process Overview
The laboratory analysis of a drug test is broken down into four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the introductory handling of a sample within the laboratory's system. This step ensures the sample is properly sealed and sent, assigns it a LAN (Laboratory Accessioning Number), and completes any extra data requirements not supplied by an electronic custody protocol.
Screening provides an initial assessment for drug presence. Though Screening offers a cost-efficient means to detect drug use for most samples, any findings indicating drug presence require further validation to be considered credible in legal contexts. Samples marked as presumptively positive during Screening must undergo a subsequent confirmation process.
When a sample tests positive during the Screening process, more hair is extracted from the initial batch for the Extraction phase. Here, drugs are extracted from hair at lower levels compared to other techniques like urine or saliva, underscoring the complexity of conducting a hair drug test.
Positive results in Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before the Confirmation stage if necessary. The complete process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Note: The so-called "hair follicle test" assesses the hair strand itself, not the follicle under the scalp.
