Hair testing is recognized as an effective means for identifying drug and alcohol use. This method captures a long-term history of substance use by entrapping biomarkers within the strands of growing hair. When acquired near the scalp, hair can reveal a detection timeline of up to roughly 3 months for drugs and alcohol. It is easy to gather, challenging to falsify, and straightforward to transport.
An ideal 1.5-inch sample, approximately 200 strands of hair in volume (akin to the size of a #2 pencil), closest to the scalp provides around 100mg, which is optimal for both screening and confirmation. For additional tests, like EtG, or those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for accurate weighing. If scalp hair is not an option, a comparable amount of body hair can be utilized. When we reference head hair, we specifically mean scalp hair. Body hair includes all other hair kinds (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial processing of the sample within the lab system. This step ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not included in an electronic chain of custody system.
Screening performs an initial rapid assessment for illicit drugs. Although it is a cost-efficient method for ruling out drug use in most cases, any positive findings need to be verified to be valid in a legal context. Presumptive positives from Screening necessitate a subsequent confirmation.
If the Screening phase indicates a presumptive positive, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is more challenging to execute.
Confirmation of any positive results from screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation as necessary. The full laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
