The use of hair tests has become recognized as an effective method for identifying the usage of drugs and alcohol. Hair captures biomarkers within its fibers, offering an extended history of substance consumption. When hair is gathered near the scalp, it can reveal a detection period of up to around three months for alcohol and drugs. The collection of hair is straightforward, posing challenges to tampering, and is efficiently shipped.
A segment measuring 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil’s size) located near the scalp provides around 100mg, which is the preferred sample mass for both screening and confirmation processes. For tests such as EtG, additional panels, or any test exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for measuring the sample. In scenarios lacking scalp hair, a similar quantity of body hair is an acceptable alternative. In this context, head hair indicates specifically scalp hair, while body hair encompasses all other forms (including facial, axillary, etc.).
Process Overview
The lab processing of a drug test outcome encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial management of a specimen within the laboratory framework. It entails verifying the intact seal and proper shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input which isn’t covered by an electronic chain of custody setup.
Screening offers a preliminary rapid assessment for substances of abuse. While Screening provides a cost-efficient solution for excluding drug usage in most samples, favorable screens require confirmation to be valid in legal settings. Samples that indicate potential positivity during Screening must undergo secondary validation.
Upon a positive indication during the Screening stage, further hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations than alternative approaches (such as urine or oral fluid), making hair drug screening the most challenging technique to execute.
Subsequent Confirmation of any positive results is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All preliminarily positive samples are subject to washing before confirmation when needed. The comprehensive laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.
