Hair testing is recognized as an effective instrument for identifying drug and alcohol consumption. Hair offers an extensive history of substance use by capturing biomarkers within the fibers of the continuously growing hair. When taken directly from the scalp, hair can reveal drug and alcohol usage for up to around three months. The collection process is straightforward, it is relatively challenging to tamper with, and can be easily mailed.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) taken nearest to the scalp will provide 100mg of hair, which is the optimal quantity for testing and verification. For EtG, additional tests, and/or panels exceeding 10, a specimen amounting to 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, a comparable quantity of body hair is acceptable. When we mention head hair, it specifically pertains to scalp hair. Body hair includes all other hair forms (facial, axillary, etc.).
Process Overview
The four primary stages in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary intake of a sample into a lab’s protocol. This step ensures the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data input absent from an electronic chain of custody framework.
Screening entails a preliminary evaluation for illegal substances. While screening economically determines drug absence in most samples, a confirmed positive result is mandatory for legal proceedings. Samples indicating a presumptive positive in Screening necessitate an additional verification step.
In the event of a presumptive positive finding in the Screening phase, additional hair is extracted from the initial sample and set for Extraction, where substances are extracted from hair at a significantly lower concentration than alternative methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS or LC/MS/MS methods. Presumptive positive samples are cleansed before confirmation if necessary. The entire laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
