Hair analysis has emerged as an effective instrument for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drugs by capturing biomarkers within the strands of hair as they grow. A sample taken close to the scalp can offer an approximate 3-month detection window for alcohol and drugs. Hair sampling is straightforward, relatively resistant to tampering, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (aproximating the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional panels, and/or tests beyond 10 panels, 150mg of the sample is advisable. It's best to weigh the sample using a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, we refer specifically to scalp hair. Body hair encompasses all other hair varieties (beard, underarm, etc.).
Process Overview
The laboratory processing of a drug test consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a lab's system. This phase ensures that the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.
Screening provides a preliminary assessment for drug presence. While it offers an economical means of dismissing drug usage in most samples, a positive screen demands confirmation to hold legal validity. Samples presumed positive during Screening necessitate further confirmation.
If Screening indicates a presumptive positive, additional hair is retrieved from the original sample for the Extraction process. Here, drugs are drawn from the hair at significantly diminished concentrations compared to other methods (e.g., urine or saliva), making hair drug screening the most intricate method to execute.
Confirmed positive screening results undergo validation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned before confirmation as necessary. The whole lab process, from Accessioning through Confirmation, undergoes review adhering to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Referred to frequently as "hair follicle tests", the test itself evaluates the hair strand and not the follicle under the scalp.
