Hair analysis has gained recognition as an effective means to identify drug and alcohol consumption. The strands offer an extensive timeline by retaining substance biomarkers in the hair's fibers as it grows. When sampling near the scalp, the detection window for substances extends up to roughly three months. The process of collecting hair is straightforward, it is relatively resistant to altering, and it is simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 strands (approximately the thickness of a #2 pencil) closest to the scalp, yields about 100mg, which is the optimal quantity for both screening and confirmation. For EtG evaluations, additional checks, or tests exceeding 10 panels, it is advised to collect 150mg of the sample. Using a jeweler’s scale for weighing the specimen is advised. If scalp hair is not present, a similar volume of body hair can be acquired. In discussions of head hair, the focus is strictly on scalp hair. All other types fall under body hair (facial, axillary, etc.).
Process Overview
The process to derive a drug test result in the lab is comprised of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning represents the initial phase where the sample enters a lab's system. This stage ensures the sample is properly sealed and conveyed, assigns it a unique LAN (Laboratory Accessioning Number), and completes any data input absent from an electronic custody chain system.
Screening serves as a preliminary rapid assessment for substances. Screening is an economical approach to exclude drug presence in most instances; however, a positive result requires confirmation for judicial acceptance. Samples indicating presumptive positive results during Screening necessitate subsequent verification.
Presumptive positives in Screening lead to additional hair being retrieved from the initial sample for the Extraction phase. Drugs are removed from hair at much lower concentrations here than other approaches (e.g., urine or oral fluids), making hair drug testing the most complex to execute.
Any positive outcomes from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Positive samples are washed if necessary before finalizing Confirmation. The entire process from Accessioning to Confirmation undergoes assessment for CAP (College of American Pathologists) Hair designation, alongside ISO / IEC 17025 accreditation checks.
Advantages of hair drug testing:
Limitations:
Note: Despite being called "hair follicle tests", the focus of the test is on the hair strand itself, not the follicle beneath the scalp.
