Hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by retaining biomarkers within the strands as they grow. A sample taken near the scalp can reveal alcohol and drug use over a span of roughly three months. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
Collecting a 1.5-inch segment containing approximately 200 hairs (comparable in thickness to a #2 pencil) from the scalp yields 100mg of hair, which is the ideal amount for testing and verification. In cases requiring EtG, additional analyses, and/or more than ten panels, a recommended specimen size is 150mg. It's suggested to use a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, an equivalent quantity of body hair is suitable. When mentioning head hair, it refers exclusively to hair from the scalp, while body hair covers other types (face, armpits, etc.).
Process Overview
The four fundamental phases in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning means the initial integration of the sample into the lab’s system. This step verifies proper sealing and shipping, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes data entry not managed by an electronic chain of custody.
Screening performs a rapid preliminary check for drug presence. Though Screening is an affordable method to exclude drug use from most samples, any positive result must be verified to hold up legally. Samples that test positive during Screening require subsequent verification.
If Screening suggests drug presence, additional hair is drawn from the original sample for Extraction. In this phase, the concentration of drugs extracted is significantly less than in other methods (e.g., urine or saliva), which accounts for the complex nature of hair drug analysis.
Verification of any positive result from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
