Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a lengthy record of alcohol and other drugs by embedding biomarkers in the strands of growing hair. When collected near the scalp, hair can offer a detection period of up to around three months for alcohol and other substances. Hair is straightforward to gather, challenging to tamper with, and simple to transport.
A 1.5-inch portion consisting of approximately 200 hair strands (about the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the ideal quantity for examination and validation. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair isn't accessible, an equivalent amount of body hair may be taken. When referencing head hair, we mean hair on the scalp exclusively. Body hair refers to all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory system. This involves confirming the sample was sealed and shipped appropriately, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.
Screening includes an initial rapid assessment for drugs of abuse. Although Screening is a cost-effective method to exclude drug use in most samples, a positive screen must be confirmed to be admissible in legal proceedings. Any samples with presumptive positive results in Screening require a secondary confirmation.
If a sample shows a presumptive positive result in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this process, drugs are extracted from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
