Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by incorporating biomarkers into the strands as they grow. When collected near the scalp, hair can offer roughly a 3-month window for detecting alcohol and other drugs. Hair is easy to collect, somewhat hard to contaminate, and convenient to ship.
A 1.5-inch sample consisting of about 200 strands of hair (about the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the ideal quantity for screening and confirmation. For EtG, additional testing, and/or tests exceeding 10 panels, a 150mg sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is unavailable, a comparable amount of body hair can be used. When mentioning head hair, we mean scalp hair exclusively. Body hair refers to all other hair types (facial, axillary, etc.).
Process Overview
The primary phases in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into a laboratory’s system. This process ensures that the sample was sealed and forwarded correctly, attaches a random LAN (Laboratory Accessioning Number), and completes any additional data entry not handled by an electronic chain of custody system.
Screening performs a preliminary rapid evaluation for drug misuse. While Screening is a cost-efficient approach to exclude drug use in most samples, any positive screen must be confirmed for it to be court-admissible. Samples that are initially positive in Screening necessitate further confirmation.
If a sample is preliminarily positive during Screening, additional hair is taken from the sample for Extraction. At this stage, drugs are extracted from hair at a lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening one of the more challenging methods to execute.
Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive results are washed before confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is monitored under the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
