Hair analysis has emerged as a robust method for identifying the use of substances like drugs and alcohol. The fibers of hair strands capture biomarkers, creating a comprehensive record of substance use over an extended period. When hair is collected near the scalp, it can reveal substance use over a detection window of roughly three months. Collection of hair is straightforward, hard to tamper with, and easy to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) cut from the scalp, yields 100mg of hair, which is the optimal quantity for both initial screening and subsequent confirmation tests. If you're conducting tests such as EtG or panels exceeding 10 drugs, a 150mg specimen is preferred. It's advisable to weigh the specimen using a jeweler's scale. If scalp hair isn't available, an equivalent quantity of body hair can be gathered. When referring to head hair, we specifically mean scalp hair. Other body hair includes facial, axillary, and similar types.
Process Overview
The laboratory results for a drug test undergo a series of four critical stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing within the lab system. This involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing necessary data entry not covered by an electronic chain of custody system.
Screening serves as the preliminary test for detecting drugs. Though cost-effective for ruling out drug use in most cases, a positive screening necessitates confirmation for legal admissibility. Samples identified as presumptively positive in Screening mandate further confirmation.
For samples testing positive during Screening, additional hair is extracted from the original specimen, prepping it for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations compared to other testing methods like urine or oral fluid, which makes hair testing a challenge.
Confirming any positive screening result utilizes techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any samples deemed presumptive positive are washed before confirmation as required. Both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards guide the complete process from Accessioning through Confirmation.
