The analysis of hair samples is recognized as an effective means to identify drug and alcohol usage. Hair offers an extended overview of substance consumption by embedding indicators in the fibers of the hair as it grows. When collected near the scalp, it provides approximately a three-month detection timeframe for alcohol and drugs. The collection of hair is straightforward, relatively tamper-proof, and simple to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil) from near the scalp yields 100mg of hair, the perfect quantity for both screening and verification. For EtG, additional tests, or analyses beyond 10 panels, 150mg of hair is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not accessible, an equivalent amount of body hair can be collected. When we mention head hair, we refer exclusively to scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of entering a sample into a lab’s framework. It includes confirming that the sample was correctly sealed and shipped, creating a random LAN (Laboratory Accessioning Number), and finalizing additional data entry not covered by an electronic chain of custody system.
Screening is a swift initial assessment for substances of abuse. While Screening is an economical method to eliminate drug presence in most samples, a positive result must be confirmed to be considered valid in legal scenarios. Any sample that tests presumptively positive in Screening requires an additional confirmation.
For samples indicated as presumptively positive during Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, substances are extracted from hair at much lower concentrations than with other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Confirmation of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if needed. The complete process from Accessioning to Confirmation is assessed per the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
