Hair analysis has garnered recognition as an effective approach for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and drug usage by capturing biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can offer up to a three-month window of detection for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately matching the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is optimal for analysis and corroboration. For EtG, additional tests, and/or panels exceeding ten, it is advised to use 150mg of the sample. It is advisable to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair can be collected. When mentioning head hair, we exclusively mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory's drug testing process encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory's system. This process includes verifying proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and executing any supplementary data input not covered by the electronic chain of custody system.
Screening entails an initial rapid assessment for drug presence. Although Screening is economical for excluding drug use in most cases, a positive indication warrants confirmation for admissibility in legal settings. Samples suspected as positive during Screening necessitate additional confirmation.
If a sample indicates potential positivity in the Screening phase, further hair is drawn from the initial sample for Extraction. In this phase, drugs are extracted from the hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), establishing hair drug screening as the most challenging method to execute.
Confirmation of any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples assumed positive are cleansed before confirmation as required. The entire laboratory workflow from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
