Hair analysis has become recognized as an effective means for identifying drugs and alcohol consumption. Hair retains a historical record of substances by integrating biomarkers within the hair fiber as it grows. When taken near the scalp, hair can reveal substance use information for up to roughly 90 days. Hair is easy to gather, not easily tampered with, and straightforward to transport.
A segment of hair measuring 1.5 inches with around 200 strands (comparable in size to a #2 pencil) closest to the scalp can deliver 100mg of hair, considered perfect for analysis and validation. For EtG, additional evaluations, and/or tests exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair is not present, an equivalent volume of body hair may be used. Head hair pertains solely to scalp hair, whereas body hair signifies all other types (facial, axillary, and so on).
Process Overview
The four essential phases in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary input of a sample into a lab’s database. This involves affirming the sample was secured and sent correctly, allotting a random LAN (Laboratory Accessioning Number), and fulfilling any supplemental data entry absent from an electronic chain of custody protocol.
Screening engages in a preliminary swift evaluation for drugs of abuse. Although Screening is economical for dismissing drug utilization in the majority of samples, a positive screen must be confirmed to attain legal credibility. Any samples that yield a preliminary positive during Screening need a follow-up confirmation.
Should a sample appear presumptively positive during the Screening phase, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), which is why hair drug analysis is among the most complex methodologies to execute.
Verification of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes a wash before confirmation if necessary. The complete laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair categorization and per the ISO / IEC 17025 accreditation standards.
