Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. By trapping biomarkers within its strands, hair provides an extended history of substance use. When obtained near the scalp, it offers approximately a 3-month detection timeframe for alcohol and other substances. Hair is easy to gather, less prone to tampering, and convenient for shipping.
A sample measuring 1.5 inches from about 200 hairs (equivalent to the thickness of a #2 pencil) closest to the scalp gives 100mg, ideal for both screening and confirmation purposes. For EtG, additional, and/or tests exceeding 10 panels, a 150mg sample is suggested. We recommend weighing the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair can be used. When mentioning head hair, we refer exclusively to scalp hair. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is divided into four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is initially processed into a laboratory’s system. This step includes verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.
Screening involves an initial rapid test for substances of abuse. Though Screening is a cost-effective method to eliminate drug use in most samples, a positive result requires confirmation for admissibility in court. Samples that yield a presumptive positive in Screening necessitate secondary confirmation.
If Screening results in a presumptive positive, additional hair is taken from the original sample for Extraction. During this phase, substances are extracted from hair at lower concentrations than with other methods (e.g., urine or oral fluid), which makes hair drug screening more challenging to execute.
Confirmation of any positive results from Screening is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
