Hair analysis has emerged as a robust method for identifying substance use, including drugs and alcohol. Hair deposits a timeline of drug and alcohol intake by embedding biomarkers within the hair's structure as it grows. When hair is sampled near the scalp, it offers a detection capability spanning up to about three months for drugs and alcohol. It is straightforward to collect, hard to tamper with, and conveniently shipped.
A sample measuring 1.5 inches consisting of roughly 200 hair strands (equivalent to a #2 pencil's diameter) located nearest to the scalp will yield 100mg of hair, which is optimal for screening and confirmation. For EtG analysis, add-on tests, and/or examinations beyond ten-panel configurations, collecting 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair cannot be obtained, an equivalent quantity of body hair may be utilized. When referring to head hair, it pertains exclusively to scalp hair, while body hair encompasses all other hair types (i.e., facial, axillary, etc.).
Process Overview
The main procedural steps for processing drug test outcomes in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing phase where a specimen is logged into a lab’s system, ensuring that it was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and addressing any additional data entry requirements absent from an electronic custody chain system.
Screening involves a preliminary swift evaluation for substance misuse. While economical for dismissing drug usage in the majority of specimens, corroboration is needed for any positive screen for courtroom acceptability. Samples showing preliminary positive results in Screening necessitate follow-up confirmation tests.
For samples yielding a potential positive during the Screening process, additional hair is drawn from the original specimen and readied for Extraction. At this step, drugs are isolated from hair at notably lower concentrations than in other methods (e.g., urine or saliva), highlighting the complexity of performing hair drug screening.
Confirmation of any Screening-positive results is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumptive of a positive result undergo washing before confirmation as essential. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair identification and complies with ISO / IEC 17025 standards.
