Hair analysis is now seen as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive history of substances by ensnaring biomarkers within the fibers of its growing strands. When hair is taken close to the scalp, it can reflect a detection span that extends up to around three months for alcohol and other drugs. The collection of hair is straightforward, generally resilient to tampering, and simple to transport.
A specimen measuring 1.5 inches of roughly 200 hair strands (similar to the width of a #2 pencil) near the scalp equates to 100mg of hair, the optimal sample amount for both screening and verification. For EtG, additional screenings, or tests involving more than 10 panels, a sample of 150mg is advised. Utilizing a jeweler’s scale for weighing the specimen is suggested. If scalp hair is unavailable, a comparable quantity of body hair can be used. References to head hair specifically pertain to scalp hair, while body hair encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The key stages in laboratory drug test processing encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary incorporation of a sample into a laboratory’s framework. This phase includes confirming the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and entering any supplementary information not available through an electronic chain of custody system.
Screening involves an initial rapid assessment for drug abuse. While Screening is a cost-efficient method for excluding drug use in most samples, a positive finding requires confirmation to be usable in legal settings. Any sample indicating a potential positive in Screening mandates further confirmation.
Should a sample show potential positive results in the Screening phase, additional hair is taken from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at concentrations much lower than those in other drug testing methods (e.g., urine or oral fluid), highlighting the complexities of performing hair drug screening.
Any positive screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The entire laboratory pathway from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair title and accreditation by ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly known as "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
In Nelson, VA, hair follicle testing outperforms urine testing significantly. While traditional urine tests are common, hair tests provide much longer detection timeframes and can identify substance use from months prior, giving them an edge in thoroughness and dependability.
Employers and other stakeholders benefit from superior detection accuracy, reducing the chances of false negatives and missed drug histories. Such thoroughness makes hair follicle tests a much-preferred choice in many scenarios.
In Nelson, VA, hair follicle tests stand out with their extended detection window. These tests can uncover drug use over as long as 90 days, offering employers an exhaustive insight into an individual's substance consumption patterns over an extended period.
This lengthy detection capability helps in understanding prolonged behaviors rather than just recent activities, which is especially critical in industries where safety and reliability are paramount.
Offering a tamper-resistant testing method, hair follicle tests in Nelson, VA, significantly diminish the risks associated with sample adulteration. Since hair samples are collected under strict observation, opportunities for cheating or switching samples are minimized.
This feature provides unquestionable results that stakeholders can depend on, thus reinforcing integrity and trust in the testing process.
