Hair testing is now recognized as a robust method for identifying drug and alcohol consumption. Hair captures a protracted record of alcohol and drug intake by embedding biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can offer up to a roughly 3-month period of detection for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and uncomplicated to transport.
A 1.5-inch section of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will produce 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or screenings exceeding 10 panels, a 150mg sample is advisable. It's suggested to measure the sample weight with a jeweler’s scale. If scalp hair isn’t available, a similar amount of body hair can be taken. When we mention head hair, we specifically mean scalp hair, while body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The principal stages in the laboratory evaluation of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introductory handling of a sample into a laboratory’s framework. This involves ensuring that the sample was properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody process.
Screening performs an initial rapid assessment for substance abuse indicators. Although Screening is a cost-effective measure to exclude drug usage in most cases, a positive result from screening necessitates confirmation for legal admissibility. Samples with presumptive positives in Screening must undergo further confirmation.
If a sample demonstrates presumptive positivity during Screening, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are drawn from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most challenging technique to execute.
Verification of any screening positive is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleaned before confirmation if required. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation as well as being accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the scalp.
