Hair examination has increasingly become recognized as an effective method for spotting drug and alcohol consumption. Hair captures a long-standing record of substances by encasing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, it can offer a detection period of roughly 3 months for drugs and alcohol. Collecting hair is straightforward, moderately challenging to tamper with, and simple to deliver.
A sample measuring 1.5 inches with about 200 hair strands (approximately the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is the ideal amount for evaluations and confirmations. For EtG, supplementary tests, or panels surpassing 10, a 150mg sample is suggested. Utilizing a jeweler’s scale to weigh the sample is advisable. If scalp hair cannot be collected, a comparable quantity of body hair can be used. When discussing head hair, it pertains exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results includes four principal phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into a laboratory’s system. This step includes ensuring that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from an electronic chain of custody system.
Screening is a preliminary rapid assessment for substances of abuse. Although Screening is a cost-efficient method for eliminating potential drug use in most samples, a positive outcome must be validated to hold in legal proceedings. Samples that indicate a presumptive positive in Screening necessitate further confirmation.
When a sample appears presumptively positive during the Screening phase, additional hair is retrieved from the original sample for Extraction. At this point, drugs are removed from hair at far lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a highly challenging technique to execute.
Verification of any positive Screening outcome is carried out utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleansed prior to confirmation as needed. The entire laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
