Hair analysis has gained recognition as an effective method for identifying substance use. Hair retains markers of drugs and alcohol within the strand fibers over time. Collected near the scalp, hair offers an approximate three-month window for detecting alcohol and substances. It is straightforward to collect hair, tricky to tamper with, and convenient for transport.
A hair sample measuring 1.5 inches and containing about 200 strands (similar to the diameter of a #2 pencil) is ideal for screening and confirmation, yielding 100mg of hair. For tests investigating EtG, additional elements, or panels exceeding ten, a 150mg sample is advisable. It is recommended to use a jeweler’s scale for specimen measurement. In the absence of scalp hair, equivalent body hair can be used. When discussing head hair, we mean scalp hair, while body hair encompasses other areas (e.g., facial, armpit).
Process Overview
The laboratory analysis of a drug test includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are integrated into the lab system. This phase ensures the sample's proper sealing and shipment, assigns a Laboratory Accessioning Number (LAN) randomly, and completes any manual data entry absent from the electronic chain of custody.
Screening serves as an initial assessment for substance abuse, offering a cost-efficient means to eliminate drug presence in most samples. However, a positive Screening result demands Confirmation for legal admissibility. Samples showing potential positive results in Screening need further verification.
For presumptively positive Screening samples, additional hair is taken from the collected specimen to prepare for Extraction. In this phase, drugs are retrieved from hair at smaller concentrations than seen with other techniques (e.g., urine or saliva), highlighting the complexity of hair drug screening.
Positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned as needed before Confirmation. The entire procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
