Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It offers a long-term overview of drug and alcohol use by capturing biomarkers in the fibers of the growing hair. Collected near the scalp, hair samples can provide up to a 3-month detection window for substances. Hair is easy to gather, tough to tamper with, and straightforward to transport.
A 1.5-inch section of approximately 200 hair strands (about the diameter of a #2 pencil) taken close to the scalp yields 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, or panels above 10, a 150mg sample is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't available, an equivalent amount of body hair can be collected. When we mention head hair, we are specifically referring to scalp hair. Body hair refers to all other types (facial, axillary, etc.).
Process Overview
The laboratory process of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the entry of a sample into the lab’s system. This step includes ensuring that the sample was properly sealed and transported, assigning a Laboratory Accessioning Number (LAN), and completing any necessary data entry not covered by an electronic chain of custody.
Screening is a preliminary evaluation to identify the presence of drugs. It's an economical way to dismiss drug use in most samples, but a positive screening needs confirmation for legal admissibility. Any samples showing a presumptive positive in Screening require further confirmation.
If the Screening process indicates a presumptive positive, additional hair is taken from the sample for Extraction. During Extraction, drugs are extracted from the hair at significantly lower concentrations compared to other methods (like urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is rigorously reviewed under the CAP (College of American Pathologists) Hair and ISO/IEC 17025 standards.
