Hair analysis has been recognized as an efficient approach for identifying drug and alcohol consumption. Hair captures a chronological record of substances like alcohol and drugs by embedding biomarkers within the strands of hair as they grow. By obtaining hair samples close to the scalp, an observation period for substances such as alcohol and other drugs of up to about three months is feasible. The collection process of hair is straightforward, the risk of tampering is relatively low, and it can be transported easily.
A sample measuring 1.5 inches containing roughly 200 hair strands (resembling a #2 pencil in size) closest to the scalp yields 100mg of hair, which is the preferred quantity for analysis and subsequent confirmation. For assessing EtG, additional tests, or any tests exceeding 10 panels, it is advisable to collect 150mg of the sample. Utilizing a jeweler’s scale to weigh the sample is recommended. Should scalp hair be inaccessible, an equivalent volume of body hair can be acquired. Referring to head hair pertains exclusively to scalp hair, while body hair encompasses all other varieties (such as facial, axillary, etc.).
Process Overview
There are four essential phases in processing a drug test result within a lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the primary handling of a specimen within a laboratory’s framework. This process includes ensuring the sample was appropriately sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and fulfilling additional data entry requirements not covered by an electronic chain of custody arrangement.
Screening entails a rapid preliminary assessment for substances of abuse. Although Screening offers a practical method to eliminate drug usage for most specimens, it is crucial to confirm any positive screening to ensure its eligibility in legal contexts. Samples deemed presumptively positive during the Screening phase necessitate subsequent confirmation.
For specimens indicated as presumptively positive during Screening, additional hair is isolated from the initial sample for processing during Extraction. This phase extracts drugs from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug analysis among the most challenging methodologies.
Confirmation of a positive screening outcome utilizes technologies like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples presumed positive undergo washing when needed. The entire examination process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation criteria.
