Evaluation of hair samples is increasingly recognized as an effective method for identifying alcohol and drug consumption. Hair samples offer an extended view of substance intake by encasing biomarkers within the hair strand as it grows. Hair retrieved adjacent to the scalp may reveal substance use over a 90-day period for both alcohol and other drugs. Collection of hair samples is straightforward, resistant to tampering, and can be transported with ease.
A 1.5-inch segment consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) from the scalp yields 100mg, which is the optimal amount for initial screening and further validation. For EtG analysis, additional panels beyond ten, or specific add-on tests, a recommendation of 150mg is made. It’s advisable to utilize a jeweler's scale for measuring the sample. In absence of scalp hair, a sample of body hair equivalent to the required amount may be obtained. The term head hair pertains strictly to hair from the scalp, while body hair encompasses all other hair (such as facial or axillary).
Process Overview
There are four pivotal stages in the lab analysis of a drug test: Sample Entry, Initial Testing, Analysis, and Final Confirmation.
Sample Entry involves incorporating a sample into the laboratory’s framework. This process includes ensuring proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input that the electronic chain of custody system hasn’t addressed.
Initial Testing, or Screening, constitutes the preliminary examination for drug presence. Although Screening is a cost-efficient measure to exclude drug presence in many samples, it requires a confirmatory test to be legally viable. Any sample showing a presumptive positive in Screening necessitates a subsequent confirmation.
In instances of a presumptive positive result during Screening, additional hair is extracted from the original sample for Analysis. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), highlighting the intricate nature of hair drug analysis.
To authenticate any positive findings from Screening, Confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation as deemed necessary. The laboratory procedure, from Sample Entry to Confirmation, is scrutinized according to both CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed as "hair follicle tests", the analysis is conducted on the hair strand itself, not the underlying follicle.
