Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Through capturing biomarkers within the fibers of the growing hair strand, hair offers a comprehensive overview of alcohol and drug usage over time. When taken from near the scalp, hair can offer up to a 90-day detection period for alcohol and drugs. Hair is effortless to collect, presents a challenge to tamper with, and is simple to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (about the size of a #2 pencil) nearest to the scalp will yield 100mg, deemed the optimal sample size for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen size of 150mg is advised. We suggest measuring the specimen using a jeweler’s scale. Should scalp hair not be accessible, an equivalent quantity of body hair can be gathered. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (like facial or axillary).
Process Overview
The lab processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into the lab’s system, ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any leftover data entry absent from an electronic chain of custody system.
Screening consists of an initial rapid assessment for drugs of abuse. Although Screening serves as a cost-efficient means to clear most samples of drug use, a positive outcome necessitates confirmation to be court-acceptable. Presumptively positive samples at the Screening stage require additional verification.
If a sample appears presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. In Extraction, drugs are retrieved from hair at a much lower concentration than other methods (like urine or oral fluid), making hair drug analysis the most challenging method to execute.
Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives receive a wash before confirmation if needed. The complete lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair directive and the accreditation to ISO / IEC 17025 standards.
