Hair examinations have emerged as an influential method for identifying drug and alcohol consumption. Hair acts as a long-standing record of alcohol and various drugs, capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair provides nearly a 3-month window to detect alcohol and other substances. Hair is easy to collect, somewhat challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches containing roughly 200 strands of hair (comparable to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a quantity of 150mg is advised. We suggest weighing the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be collected. When referring to head hair, we imply scalp hair exclusively. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a laboratory’s system. This process ensures that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any auxiliary data entry not covered by an electronic chain of custody system.
Screening includes an initial rapid inspection for drugs of abuse. Though Screening is a budget-friendly method to eliminate drug use in most samples, a positive result in this phase requires confirmation to be permissible in legal settings. Samples that are presumably positive during Screening need a subsequent confirmation.
If a sample is deemed presumptively positive during the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at a substantially lower concentration than in other techniques (e.g., urine or oral fluid), which is why hair drug testing poses the greatest challenge to perform.
Confirmation of any positive Screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if needed. The comprehensive laboratory process from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
