Hair analysis has increasingly become recognized as a potent method for identifying drug and alcohol usage. It enables a comprehensive history of substance intake by capturing biomarkers within the hair fiber as it grows. When collected near the scalp, hair can offer an approximate 3-month detection timeline for alcohol and drug usage. Hair collection is straightforward, challenging to tamper with, and convenient for transport.
A sample measuring 1.5 inches, comprising roughly 200 hairs (similar to a #2 pencil), taken closest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, add-ons, 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 isn't available, a comparable amount of body hair can be gathered. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses hair from all other parts (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into the lab's system. It involves checking that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid test for drugs of abuse. Although Screening effectively identifies the absence of drug usage in most samples, a positive result needs confirmation for legal admissibility. Any samples that are potentially positive in Screening require further corroboration.
Should a sample appear positive at the Screening stage, additional hair is extracted from the primary specimen and prepared for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening one of the most challenging methodologies.
The final Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples are washed as necessary before confirmation. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 standards.
