Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug use by embedding biomarkers within the strands as the hair grows. When cut near the scalp, hair can present roughly a 3-month timeline for detecting alcohol and drugs. Hair is easy to gather, moderately challenging to tamper with, and simple to send.
A 1.5-inch sample consisting of about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg, which is the prime amount for testing and verification. For EtG, additional requests, and/or tests surpassing 10 panels, a 150mg sample is advised. We suggest weighing the sample with a jeweler's scale. If scalp hair is unavailable, a comparable amount of body hair can be used. When we mention head hair, we mean scalp hair exclusively. Body hair refers to all other types of hair (facial, axillary, etc.).
Process Overview
The four crucial phases in the lab assessment of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the preliminary treatment of a sample into a lab's system. This comprises confirming the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not covered by an electronic custody chain.
Screening entails an initial rapid assessment for the presence of abused drugs. Although Screening is an economical means to dismiss drug usage for most samples, a positive screen must be verified to be court-admissible. Any samples that are tentatively positive in Screening warrant a follow-up confirmation.
When a sample is tentatively positive in the Screening process, additional hair is extracted from the primary sample and prepared for Extraction. During this phase, substances are withdrawn from hair at a lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex method to execute.
Confirmation for any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if required. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
