Hair analyses have emerged as an effective method for identifying substance and alcohol consumption. Hair captures a long-term record of drug and alcohol usage by embedding biomarkers within the fibers of the developing hair shaft. When samples are taken close to the scalp, they can offer approximately a three-month detection period for substances. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (about the width of a #2 pencil) near the scalp yields 100mg of hair, the preferred quantity for analysis. For EtG, additional requests, and/or over 10 panel tests, a 150mg sample is suggested. Utilizing a jeweler’s scale for specimen weighing is advisable. Should scalp hair not be available, an equivalent amount of body hair can be collected. References to head hair specifically denote scalp hair. Body hair encompasses all other types (facial, axillary, and so on).
Process Overview
The primary phases in laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a lab’s system. This stage includes confirming that the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.
Screening entails an initial rapid examination for substances. Although Screening is a budget-friendly approach to exclude drug presence in most cases, a positive result must be confirmed to have legal standing. Samples that test presumptive positive in Screening require a follow-up confirmation.
In cases where samples test presumptive positive during Screening, more hair is taken from the primary specimen for preparation in Extraction. This process involves isolating drugs from hair at significantly lower concentrations than other methods (like urine or saliva), which is why hair drug testing is the most challenging methodology.
Any positive results from initial Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing prior to confirmation if necessary. The comprehensive lab process, from Accessioning through Confirmation, is evaluated both under the CAP (College of American Pathologists) Hair criteria and the accreditation of ISO / IEC 17025 standards.
