Utilizing hair analysis has emerged as a robust method for identifying alcohol and drug consumption. Hair fibers encapsulate biomarkers within them, thus offering an extended timeline of substance usage history. If trimmed near the scalp, hair can reveal drug and alcohol presence for a period reaching approximately three months. Its collection is straightforward, it's relatively resistant to tampering, and shipping is convenient.
A sample measuring 1.5 inches, containing around 200 hair strands (akin to a #2 pencil's diameter) nearest the scalp, yields roughly 100mg of hair, which is optimal for both screening and verification. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg sample is advised. It's suggested to measure the sample using a jeweler’s scale. In the event scalp hair is not accessible, a similar amount of body hair can be used. When discussing head hair, we refer solely to scalp hair, while body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The key four steps in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails integrating the sample into a lab's system at the outset. This stage verifies the proper sealing and shipment of the sample, assigns it a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry not addressed by an e-chain of custody.
Screening entails an expedited preliminary check for abused substances. Although screening can efficiently exclude drug use in most samples, a confirmed positive result is needed for legal proceedings. Samples suspected to yield positive results during Screening necessitate further confirmation.
Presumptively positive samples during Screening prompt additional hair extraction from the original sample for the Extraction phase. In Extraction, drugs are isolated from hair at concentrations significantly lower than those in alternative methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
A confirmed positive result in any Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed before confirmation, as required. From Accessioning to Confirmation, the entire process aligns with the CAP's (College of American Pathologists') Hair designation standards and is accredited under ISO / IEC 17025.
