Hair Follicle Drug Testing - Weathers, AR

What it is, How it works

Hair analysis is regarded as a potent means for identifying drug and alcohol consumption. Hair maintains a prolonged record of alcohol and drug use by capturing biomarkers in the strands of the hair as it grows. When sourced from near the scalp, hair can reveal an alcohol and drug detection period spanning up to roughly 3 months. Hair collection is straightforward, can be tough to tamper with, and is easily transported.

Collecting a 1.5-inch piece of about 200 hair strands (approximately the breadth of a #2 pencil) nearest to the scalp yields 100mg of hair, optimal for both screening and confirmation. For tests including EtG, add-ons, and/or those covering more than 10 panels, a 150mg sample is advised. Measuring the specimen on a jeweler’s scale is recommended. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. When discussing head hair, we refer solely to scalp hair. Body hair includes all other forms of hair (facial, axillary, etc.).

Process Overview

There are four principal stages in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the preliminary handling of a sample within a lab’s system. This process verifies that the sample was securely sealed and dispatched appropriately, assigns an accidental LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody utilization.

Screening is an initial swift assessment for drugs typically abused. Although a cost-effective approach for eliminating the possibility of drug consumption in most samples, any positive screen warrants confirmation to hold up in legal proceedings. Samples testing presumptively positive during Screening must undergo further confirmation.

Should a sample indicate a presumptive positive during Screening, more hair is extracted from the original specimen for preparation in Extraction. This phase involves extracting drugs from hair at notably lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.

Confirmation of any preliminarily positive screening outcome follows via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as needed. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the standard accreditation of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests recognize drug usage for as long as 90 days, relative to urine tests which offer a shorter detection time frame.
• Resistant to tampering: It is exceedingly difficult to manipulate a hair drug test, ensuring more trustworthy results.
• Offers historical insight: Provides a temporal overview of drug usage patterns, not merely immediate usage.

Limitations:

• Lacks detection of recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing generally incurs higher costs than other drug testing techniques.
• Result variability: Variants like hair color and individual differences in hair growth can impact drug metabolite concentration in hair.

Note: While commonly labeled as "hair follicle tests", these tests examine the strand of hair rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine testing in Weathers, AR, the former consistently comes out on top. Hair tests provide a superior detection period and deliver reliable data, leaving less room for error or manipulation. This makes hair analysis a trustworthy method for identifying substance use against the more conventional urine counterpart.

Extended Detection Window

One of the key advantages of hair follicle testing is its extended detection window in Weathers, AR. This method can trace drug use back up to 90 days, providing employers with a comprehensive overview of an individual's substance use history. This extended timeline is invaluable for making informed decisions in hiring and maintaining the integrity of workplace policies.

Tamper-Resistant Testing Method

In Weathers, AR, the hair follicle test is celebrated for its tamper-resistant attributes. The nature of hair collection and analysis significantly reduces the risk of sample adulteration. This ensures that results are accurate, unquestionable, and a true reflection of an individual’s drug history, unlike some other testing methods prone to manipulation.

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.
