Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. Hair captures a comprehensive history of drugs and alcohol by embedding biomarkers within the strands. Collected near the scalp, hair provides up to a three-month detection period for alcohol and drugs. It is easy to collect, relatively tamper-resistant, and straightforward to ship.
A 1.5-inch hair sample of approximately 200 strands (about the diameter of a #2 pencil) from the scalp yields 100mg, which is the preferred amount for screening and confirmation. For EtG, add-ons, and tests over 10 panels, 150mg is suggested. We advise using a jeweler’s scale for weighing. If scalp hair is unavailable, collect an equivalent amount of body hair. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory system. This includes verifying the sample's seal and proper shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available from an electronic chain of custody system.
Screening initially checks for drugs of abuse. Screening is a cost-efficient method to rule out drug use for most samples, but a positive screen must be confirmed for court admissibility. Samples presumptively positive in Screening require a secondary confirmation.
When a sample tests presumptively positive during Screening, more hair is extracted from the original sample and prepared for Extraction. This stage extracts drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.
Confirmation of positive screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is audited under both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
