Hair analysis has gained recognition as a robust method for detecting substance use and alcohol consumption. By capturing biomarkers within the strands of developing hair, it provides a prolonged history of alcohol and various drugs. Collected near the scalp, it can reveal drug and alcohol use over approximately a 90-day period. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of around 200 strands or roughly the width of a #2 pencil near the scalp, will yield 100mg of hair, which is optimal for both screening and confirmation. For testing EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is suggested. It is advisable to measure the weight of the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be obtained. References to head hair pertain solely to scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The laboratory process for evaluating a drug test result comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage of integrating a sample into the lab's system. This step involves checking that the sample is properly sealed and shipped, assigning it a LAN (Laboratory Accessioning Number), and completing any necessary data entry that is not managed by an electronic chain of custody system.
Screening offers an initial assessment for signs of drug abuse. Though Screening is a cost-efficient technique for eliminating drug use in most cases, a positive result requires confirmation to be accepted in legal settings. Samples testing presumptive positive during Screening must undergo further confirmation.
Should a sample test presumptively positive at the Screening phase, additional hair is taken from the original sample for preparation in Extraction. In this phase, drugs are extracted from hair at significantly lower levels compared to other methods (e.g., urine or oral fluid), which makes hair drug testing one of the more challenging methodologies.
Positive screening results are confirmed using GC/MS, GC/MS/MS or LC/MS/MS techniques. All presumptive positive samples are washed prior to confirmation if necessary. The complete process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
