Hair analysis is recognized as an effective means for tracking drug and alcohol intake. By embedding biomarkers within the hair fibers, hair yields a comprehensive record of drug and alcohol use. When taken from near the scalp, hair can offer a detection span of up to 90 days for drugs and alcohol. The collection of hair is straightforward, hard to tamper with, and conveniently transportable.
For the optimal screening and verification, a 1.5-inch piece of roughly 200 hairs (akin to the thickness of a #2 pencil) near the scalp is required to produce 100mg, the preferred sample size. For EtG, additional tests, or screens exceeding 10 panels, 150mg of hair is suggested. We advise using a jeweler’s scale for specimen measurement. Should scalp hair be inaccessible, an equivalent amount of body hair can be collected. The term head hair specifically refers to scalp hair, while body hair covers all other hair types (facial, axillary, etc.).
Process Overview
The four key stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial inclusion of the sample within a lab’s system. This step ensures the sample’s proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and wraps up any supplementary data required beyond what an electronic chain of custody document provides.
Screening represents a preliminary expedited assessment for substance abuse. Although Screening is a cost-efficient method to exclude drug use across most samples, a court-viable screen necessitates confirmation. Samples with presumptive positivity in Screening must undergo a secondary confirmation.
In cases where Screening suggests a sample is positive, additional hair from the initial sample is taken for Extraction. During Extraction, substances are derived from hair at much lower concentrations than other methods (such as urine or oral fluid), hence why hair drug analysis is the most challenging method to execute.
Confirmation for any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleaned as required. The whole laboratory procedure, spanning Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair classification and the accreditation for ISO / IEC 17025 standards.
Advantages of hair drug testing:
