Hair analysis has gained recognition as an effective method for detecting substance use related to drugs and alcohol. It retains a comprehensive record of drug and alcohol use by embedding biomarkers within the fibers of the hair as it grows. When hair is taken from near the scalp, it offers a detection span of up to three months for alcohol and drugs. The collection process is straightforward, tampering is challenging, and shipping is convenient.
A sample size of 1.5 inches, consisting of roughly 200 strands of hair (approximately the diameter of a #2 pencil), yields 100mg, which is the optimal amount for testing and confirmation. In cases requiring EtG add-ons or tests beyond 10 panels, a specimen weighing 150mg is advisable. It's suggested to measure the sample on a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. The term "head hair" is specific to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory processing of drug test results encompasses four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning relates to the preliminary processing of a sample within a laboratory’s system, encompassing verification of the sample's proper sealing and shipping, allocation of a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent from the electronic chain of custody system.
Screening serves as an initial rapid assessment for the presence of drugs. Though a cost-effective measure for eliminating drug use in most samples, confirmed positive tests are essential for legal acceptability. Samples yielding presumptive positives in Screening necessitate further confirmation.
For specimens identified as presumptively positive in Screening, additional hair is extracted from the initial sample and prepped for the Extraction phase. During this stage, drugs are isolated from the hair at considerably low concentrations, in contrast to other methods like urine or saliva testing, underscoring why hair drug screening is notably challenging.
For a confirmed positive result post-screening, technologies such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. Any samples initially testing positive undergo washing before the confirmation stage, as required. The entire laboratory procedure from Accessioning to Confirmation is conducted adhering to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
