Hair analysis is increasingly recognized as an effective approach for detecting substance use. Hair captures a prolonged record of alcohol and drug consumption by encasing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can reveal alcohol and drug use within a timeline of roughly 3 months. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches with about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp offers up to 100mg of hair, which is the optimal quantity for both screening and verification. For tests involving EtG, additional add-ons, or panels exceeding 10, a quantity of 150mg is preferred. We suggest using a jeweler’s scale for weighing the sample. Should scalp hair be unavailable, a comparable amount of body hair can be used. In terms of head hair, we specifically refer to scalp hair. Body hair includes all other hair types, such as facial, axillary, etc.
Process Overview
The four essential stages in the lab processing of a drug testing result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the upfront processing of a specimen within the laboratory’s system. This includes ensuring the sample is properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody platform.
Screening entails an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug usage in most cases, a positive screen requires confirmation to be legally valid. Any samples that test presumptively positive during Screening necessitate additional confirmation.
If a sample tests presumptively positive during Screening, additional hair is taken from the original sample and readied for Extraction. In this phase, drugs are withdrawn from hair at a substantially lesser concentration than in other techniques (e.g., urine or saliva), making hair drug screening the most challenging methodology to execute.
Verification of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo washing before confirmation if needed. The full laboratory process from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
