Hair analysis has gained recognition as an effective means for identifying substance and alcohol consumption. The hair captures long-term evidence of alcohol and drugs by holding biomarkers within the strands' fibers. A strand taken near the scalp can indicate alcohol or drug use for up to about 90 days. Hair is easy to collect, hard to tamper with, and simple to transport.
A 1.5-inch segment, approximately 200 strands (around the thickness of a #2 pencil) near the scalp, provides 100mg, which is optimal for both initial tests and confirmations. For expanded panels such as EtG or tests over 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for weighing the specimen is suggested. If scalp hair isn't available, an equivalent quantity of body hair can be obtained. "Head hair" refers specifically to scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The key phases in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the preliminary intake of samples into a lab's system. This stage verifies that samples are sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and fills in any extra data not provided by an electronic custody chain.
Screening performs an initial, fast assessment for substance misuse. Although Screening is a budget-friendly method to eliminate drug usage in most samples, a positive requires confirmation to be legally valid. All Screening presumptive positives must undergo secondary verification.
When Screening returns a presumptive positive, extra hair is taken from the original sample for Extraction. Here, drugs are extracted from hair at a notably lower concentration compared to methods like urine or oral fluid, underscoring the complexity of hair drug screening.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a wash before confirmation when necessary. The complete process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair criteria and meets ISO / IEC 17025 accreditation.
