Hair testing is now acknowledged as an effective method for detecting drug and alcohol consumption. Hair can showcase a prolonged timeline of substance use by embedding biomarkers within its growing fibers. When acquired from near the scalp, it can offer a detection range of up to three months for various substances. Hair collection is straightforward, relatively difficult to tamper with, and convenient for shipping.
A sample measuring 1.5 inches with approximately 200 hair strands (equivalent to the diameter of a #2 pencil) near the scalp will yield 100mg, which is perfect for screening and confirmation. For EtG tests, add-ons, or testing exceeding ten panels, 150mg is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair cannot be obtained, a proportionate amount of body hair is acceptable. Scalp hair refers solely to hair on the head, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s database. This step confirms that the sample remains sealed and was properly shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any pending data entry omitted by an electronic custody system.
Screening is a preliminary, swift analysis for signs of substance misuse. Though cost-efficient for negating drug use in most samples, a positive result must be validated for legal proceedings. Samples with presumptive positive results in Screening necessitate a follow-up confirmation.
Should the Screening indicate a presumptive positive, additional hair is extracted from the original sample and prepped for Extraction. Drugs are extracted at significantly reduced concentrations in hair than other methods (e.g., urine, oral fluid), making hair drug testing particularly challenging.
Positive Screening confirmations are conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples showing presumptive positive results undergo washing before confirmation if necessary. The complete laboratory journey from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
