The perception of hair testing has evolved into a crucial method for identifying drug and alcohol use, as hair provides a prolonged record of substance exposure by capturing biomarkers within the fibers of the hair as it grows. When strand samples are taken near the scalp, they can potentially indicate alcohol and drug consumption over a period extending up to three months. Hair samples are straightforward to gather, challenging to tamper with, and convenient for transportation.
Collecting a 1.5-inch segment consisting of roughly 200 hair strands closest to the scalp is ideal, as this will yield about 100mg of hair, sufficient for both screening and confirmation. For tests involving EtG, additional analytes, or more than 10 panels, a sample weighing 150mg is advised, with precise measurement recommended using a jeweler’s scale. If scalp hair isn't an option, an equivalent quantity of body hair can be collected. References to head hair specifically denote scalp hair. All other hair types, like facial or axillary, fall under the term body hair.
Process Overview
The laboratory drug testing comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory system, which involves ensuring the sample has been adequately sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and entering any supplementary data not available via an electronic chain of custody.
Screening provides an initial, rapid assessment for drugs of abuse. Although Screening offers an economical way to rule out drug use in most samples, any positive results require Confirmation to be deemed court-admissible. Samples that test presumptively positive through Screening necessitate secondary confirmation.
In cases where Screening results are presumptively positive, more hair is extracted from the original sample for the Extraction phase. At this stage, drugs are isolated from hair at a lower concentration compared to other methods (such as urine or oral fluid tests), marking hair drug testing as a methodological challenge.
When Confirmation is necessary for positive Screening results, methods like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Presumptively positive samples undergo washing before Confirmation if needed. The entire procedure from Accessioning to Confirmation is closely scrutinized under standards set by both the CAP (College of American Pathologists) Hair program and the ISO / IEC 17025 accreditation.
