Hair testing has emerged as a potent technique for identifying drug and alcohol consumption. The hair serves as an archive for long-term substance use by capturing biomarkers within the fibers of the hair as it grows. When gathered close to the scalp, hair can offer nearly a 3-month detection period for various substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for testing confirmation. In cases requiring EtG analysis, additional criteria, or tests exceeding 10 panels, a 150mg sample is advisable. It is recommended to measure the sample with a jeweler's scale. Should scalp hair be unobtainable, a comparable quantity of body hair is acceptable. The term "head hair" specifically denotes scalp hair, while "body hair" encompasses all other hair types (such as facial or axillary hair).
Process Overview
The laboratory drug testing procedure involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step involving the integration of a sample into the lab’s system. It entails ensuring the sample is securely sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening provides a preliminary assessment for potential drug use. While Screening is an economical method to identify non-positive samples, any positive results require further confirmation to be legally viable. Samples indicating potential positivity must undergo secondary verification.
Should a sample test potentially positive during Screening, additional hair is extracted for the Extraction process. Here, substances are isolated from hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Positive screenings necessitate confirmation via GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples testing potentially positive receive washing before confirmation if deemed necessary. The entire lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.
