Hair analysis is increasingly recognized as an effective method for discovering drug and alcohol consumption. Hair retains a chronological record of alcohol and other substance use by encapsulating biomarkers in the strands as they grow. When procured near the scalp, hair can reveal a detection timeline for alcohol and substances extending up to three months. Sampling is straightforward, relatively tamper-resistant, and convenient to transport.
An ideal sample involves collecting a 1.5-inch segment of approximately 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp, yielding about 100mg of hair, which is optimal for both screening and confirmation. For EtG plus additional tests or panels exceeding 10, a 150mg sample is suggested. Using a jeweler’s scale for specimen weighing is advisable. In cases where scalp hair isn’t accessible, a comparable amount of body hair can be collected. Head hair pertains specifically to scalp hair, while body hair encompasses all other types (beard, underarm, etc.).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is introduced into the lab system. This stage involves ensuring the sample was properly sealed and shipped, assigning a random Laboratory Accessioning Number (LAN), and completing any additional data entry not covered by an electronic chain of custody system.
Screening acts as an initial assessment for the presence of drugs of abuse. This cost-effective approach efficiently rules out drug use in the majority of samples. However, any positive screening result must undergo further confirmation to be valid in legal contexts. Samples that test presumptively positive in the Screening phase require a subsequent confirmation process.
In cases of presumptive positive results in the Screening phase, additional hair is extracted from the original specimen for further processing during the Extraction step. At this stage, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or saliva samples), which makes hair drug testing particularly intricate.
Confirmation of positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washes as required before confirmation. The comprehensive laboratory process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests," the analysis targets the hair strand, not the follicle beneath the scalp.
In Sandy Valley, NV, comparing hair follicle testing to traditional urine tests highlights several advantages. Hair testing delivers superior accuracy due to its extended detection window, capturing a broader history of substance usage. It greatly minimizes false negatives, offering clear insights into an individual’s exposure to drugs.
While urine tests primarily detect recent substance use, hair tests analyze patterns longer into the past. This allows employers to understand behavior more comprehensively, aiding in maintaining rigorous safety standards.
Hair follicle tests in Sandy Valley, NV, offer an exceptional detection window, spotting drug usage up to 90 days past. This extended period is invaluable for employers who need to assess the long-term substance habits of their employees. Providing a fuller picture aids in maintaining a secure work environment.
This prolonged window ensures that past substance use does not go unnoticed, reducing incidents related to impaired abilities and securing more responsible workplace conduct.
The reliability of hair follicle testing in Sandy Valley, NV, comes from its tamper-resistant nature. Unlike other testing methods, the sample is hard to alter, ensuring the accuracy of results. This reduces the likelihood of sample manipulation, providing an authentic report on an individual's substance use.
