The utilization of hair analysis has emerged as an effective approach for identifying the use of drugs and alcohol. Hair captures biomarkers within the strands as they grow, providing a comprehensive history of substance usage. When hair is cut close to the scalp, it can reveal a detection period of nearly three months for alcohol and drug use. The collection of hair is straightforward, tough to tamper with, and convenient for transportation.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil in size) near the scalp amounts to 100mg, which is optimal for both screening and confirmation tests. For EtG, additional testing, or tests exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample with a jeweler's scale. In cases where scalp hair is not available, a similar quantity of body hair is acceptable. When mentioning head hair, it specifically pertains to scalp hair. In contrast, body hair includes all other types (such as facial and axillary hair).
Process Overview
The processing of drug test results in a laboratory encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is systematically entered into the laboratory's system. It confirms the sample was appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.
Screening acts as a preliminary drug abuse check. Although it saves costs by ruling out drug use in most samples, a positive screen mandate confirmation for legal admissibility. Samples found presumptively positive in Screening require further confirmation.
In instances of presumptive positivity at the Screening stage, additional hair from the original sample undergoes Extraction. Here, the drugs are isolated from hair at much lower concentrations than other methods (such as urine or oral fluid), marking hair drug tests as the most challenging to conduct.
Positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptive positive samples are cleansed as needed. The lab procedures, from Accessioning to Confirmation, are examined under the regulatory frameworks of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard.
