Hair testing is increasingly regarded as an effective means for identifying substance use. Hair retains a prolonged record of alcohol and drug consumption by embedding biomarkers within the keratin fibers of the growing hair strand. When taken near the scalp, hair can offer nearly a three-month detection span for substances. Hair is straightforward to gather, challenging to tamper with, and convenient for transporting.
Collecting a 1.5-inch segment of approximately 200 hair strands (comparable to the diameter of a #2 pencil) from the scalp provides a 100mg sample, optimal for initial and confirmatory testing. For EtG, additional screenings, or tests exceeding 10 panels, 150mg is advised. Utilizing a jeweler’s scale for specimen measurement is recommended. If scalp hair is not available, a similar amount of body hair can be used. When mentioning head hair, we refer solely to scalp hair, while body hair encompasses all other hair types (e.g., facial, axillary).
Process Overview
The procedure of analyzing a drug test result comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample within a lab's system, which includes confirming that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening is a preliminary, rapid assessment for substances of abuse. Although Screening offers a cost-efficient method to exclude drug use in most instances, any positive screen must be validated for legal admissibility. Samples yielding a presumptive positive in Screening necessitate additional confirmation.
When a Screening stage result indicates a presumptive positive, further hair is extracted from the original sample and prepped for Extraction. During Extraction, substances are retrieved from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
Confirmation of a positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process prior to confirmation as needed. The laboratory cycle from Accessioning to Confirmation is assessed against both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
