Hair analysis is now recognized as an effective method to identify drug and alcohol consumption. Hair retains a historical record of various substances by embedding biomarkers within the hair's growing fibers. When obtained near the scalp, it can reflect substance use for a duration of up to three months. Hair is easy to collect, fairly resistant to tampering, and simple to transport.
A 1.5-inch sample comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferable amount for testing and verification. For EtG, additional tests, or panels exceeding 10, 150mg of the hair is advisable. It is suggested to use a jeweler’s scale for accuracy. If scalp hair is not present, a similar amount of body hair can be used. References to head hair specifically mean scalp hair. Body hair encompasses all other categories (such as facial or underarm hair).
Process Overview
The laboratory processing of drug test findings is comprised of four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the preliminary handling of a sample upon its entry into a lab's framework. It covers the verification that the sample is properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any needed additional data input that an electronic chain of custody does not cover.
Screening entails an initial assessment for substance abuse. Although it is an affordable means to exclude drug consumption in most cases, a positive result from Screening must be validated to stand in legal settings. Therefore, any samples that show a presumptive positive result in Screening require secondary verification.
If Screening suggests a positive result, more hair from the original sample is drawn for the Extraction phase. Here, substances are isolated from the hair at much more diluted levels compared to other methods (such as urine or oral swab), rendering hair drug screening a highly challenging technique.
Verification of any positive results from screening happens through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and in alignment with ISO / IEC 17025 norms.
