Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of drugs and alcohol by preserving biomarkers within the fibers as the strand grows. When taken close to the scalp, hair can offer a detection period of up to around three months for alcohol and drugs. It's easy to gather, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the size of a #2 pencil) near the scalp, provides 100mg of hair, which is ideal for testing and confirmation. For EtG, add-ons, and/or panels exceeding 10, a sample of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair cannot be sourced, a similar quantity of body hair is acceptable. By head hair, we mean scalp hair only, whereas body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The core steps of lab-based drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial sample processing into a lab's records. This step ensures the sample was well-sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and enters any data not fully captured by an electronic chain of custody.
Screening provides a preliminary assessment for drug use. Although Screening is economical for ruling out drug use in most samples, any positive result must be confirmed for court admissibility. Samples that test presumptively positive in Screening require further confirmation.
For samples that show presumptive positivity during Screening, additional hair from the original collection is prepared for Extraction. Drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair testing a highly complex procedure.
Confirming a positive screen involves GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. From Accessioning to Confirmation, the whole lab process is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly known as "hair follicle tests", the examination analyzes the hair strand rather than the follicle beneath the scalp.
