Hair Follicle Drug Testing - Delta, CA

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug usage by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can offer up to a three-month detection timeframe for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.

Taking a 1.5-inch section of roughly 200 hairs (close to the thickness of a #2 pencil) from near the scalp will yield 100mg of hair, which is the optimal amount for analysis and verification. For tests like EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. It's recommended to use a jeweler’s scale for weight assessment. If scalp hair cannot be collected, a similar quantity of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other types (beard, underarm, etc.).

Process Overview

The key stages of lab processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing into the lab’s system. This involves ensuring that the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening provides an initial quick assessment for substance abuse. Screening is an economical method to rule out drug use for most samples, but a positive result from screening must be confirmed to be legally valid. Any sample that shows a presumptive positive result during Screening requires a subsequent confirmation.

Should a sample show a presumptive positive during Screening, additional hair is taken from the initial sample and readied for Extraction. In this phase, drugs are removed from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), validating why hair drug testing is among the most challenging methodologies.

Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as needed. The entire laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, compared to urine tests which have a shorter detection window.
• Difficulty to cheat: It is very difficult to cheat a hair drug test, making the results more accurate.
• Provides historical data: It can provide a pattern of drug use over a period of time, not just recent use.

Limitations:

• Cannot detect recent use: It takes approximately 5-7 days for drugs to be detectable in hair.
• Cost: Hair drug tests are generally more expensive than other drug testing methods.
• Variations in results: Factors such as hair color and individual variations in hair growth can affect the concentration of drug metabolites in the hair.

Note: Though commonly called "hair follicle tests," the examination focuses on the hair shaft and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Delta, CA, hair follicle testing stands out compared to traditional urine tests. One of the primary benefits is its superior detection accuracy, offering a comprehensive view of drug usage over an extended period. Hair tests are less prone to manipulation than urine tests, ensuring the reliability of results. This accuracy is beneficial for employers and legal systems seeking the highest standard in drug testing.

Extended Detection Window

With an extended detection window, hair follicle testing in Delta, CA provides crucial insights into an individual’s substance use over as long as 90 days. This broad timeframe allows employers to accurately evaluate an applicant's historical substance use, providing a fuller picture than shorter-detection methods. Such detailed insights are invaluable for maintaining workplace integrity and safety standards.

Tamper-Resistant Testing Method

In Delta, CA, hair follicle tests offer a tamper-resistant method of drug testing. The difficulty in adulterating hair samples significantly reduces the risk of compromised results. This robustness against sample tampering ensures that the outcomes are reliable and unquestionable, maintaining the integrity and credibility of the testing process, a necessary feature for any compliant drug-free workplace program.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
