Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair can record a comprehensive history of alcohol and drug intake by encapsulating biomarkers within the fibers of the continuously growing hair strand. When sampled near the scalp, hair can reveal a detection period for alcohol and other substances extending up to around 90 days. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for testing and verification. For EtG, additional examinations, and/or tests exceeding 10 panels, a specimen weighing 150mg is advised. It is recommended to use a jeweler’s scale for weighing the sample. In cases where scalp hair is not available, an equivalent portion of body hair may be acquired. In discussing head hair, we mean only scalp hair. Body hair denotes all other hair forms (facial, axillary, etc.).
Process Overview
The key steps in processing a laboratory drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial integration into a lab's system. This step involves verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any unfinished data entry not provided by an electronic chain of custody.
Screening offers a preliminary assessment for drugs of abuse. While Screening is a cost-efficient way to dismiss drug use across most samples, any positive result requires validation to be legally viable. Samples with a presumptive positive outcome in Screening must undergo a confirmation.
If a sample returns a presumptive positive in the Screening stage, additional hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Positive screening results are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if needed. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair certification and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
While traditional urine tests have long been a part of drug screening, hair follicle tests offer unmatched advantages in Weedpatch, CA. Their higher accuracy and reliability ensure broader detection of substance usage. Employers are shifting towards this method, valuing its ability to capture a history of drug abuse where urine sampling may fall short.
The strength of hair testing lies in its precision. Unlike urine tests, which have a limited window, hair samples provide a multi-month perspective on drug consumption. This extensive detection capability allows for a detailed evaluation, surpassing traditional methods significantly.
Hair follicle testing in Weedpatch, CA, provides a broader detection window, recognizing drug usage up to 90 days prior. This extensive scope captures an individual's substance history, offering a comprehensive view for employers seeking in-depth drug use insights.
The extended detection capability ensures that sporadic drug users are identified, providing more consistent and transparent results than traditional testing methods. This broader timeline enhances drug screening efficacy by covering a far-reaching examination period.
Reliability is a hallmark of hair follicle tests, especially in Weedpatch, CA. The tamper-resistant nature of these tests ensures that results remain authentic and uncontaminated. Hair samples reduce the likelihood of adulteration, a common issue in other forms of drug testing.
