Hair analysis has established itself as an effective method for identifying drug and alcohol consumption. The strands offer a long-term overview of alcohol and drug use by encapsulating biomarkers within their fibers. When hair is gathered near the scalp, it can reveal alcohol and drug use for a period of approximately three months. The collection process is straightforward, making tampering difficult, and shipping is uncomplicated.
A sample measuring 1.5 inches long with around 200 hairs (approximately #2 pencil size) closest to the scalp provides 100mg, which is the perfect sample size for testing and validation. For EtG, add-ons, and/or exams above 10 categories, 150mg of the specimen is advised. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair isn't accessible, an equivalent amount of body hair can be utilized. Head hair refers exclusively to scalp hair, while body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The lab test process mainly involves Accessioning, Screening, Extraction, and Confirmation stages.
Accessioning is about the initial handling of a sample within a lab. This involves confirming that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and handling any additional data input that's not part of an electronic custody record.
Screening is a preliminary check for drug presence. Though Screening is a cost-efficient method for negating drug use across many samples, a positive result needs confirmation to hold up in legal settings. Samples showing presumptive positive outcomes in Screening require further confirmation.
When a Screening yields presumptive positive results, extra hair is extracted from the original sample for Extraction. During Extraction, drugs are retrieved from hair at concentrations lower than those in urine or oral fluid testing, making hair testing the most intricate method.
Confirmation of positive Screening outcomes employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any sample showing presumptive positivity undergoes a wash prior to confirmation as necessary. The whole lab procedure, from Accessioning through Confirmation, is audited under CAP (College of American Pathologists) Hair standards and adheres to ISO / IEC 17025 accreditations.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests," the test targets the strand itself rather than the follicle beneath the scalp.
