Accredited Drug Testing provides comprehensive hair follicle drug testing services in Centralia, Illinois. Whether you require drug or alcohol hair testing, Accredited Drug Testing has expertise in this area, with facilities available in every city across the country to handle hair tests. Typically, 1.5 to 2 inches of head or body hair is needed. Hair samples can be tested for substances like drugs, alcohol/ETG, or other specialized options.

Over recent times, drug testing methods have increasingly incorporated hair follicle tests. Many employers, judicial systems, and substance abuse experts now prefer hair testing over urine tests. This technique is essential for employers enforcing strict no-drug policies, court proceedings, and individuals under probationary conditions. The key advantage of hair follicle testing is the extended timeframe for drug detection, generally up to 90 days, and the difficulty in tampering. However, urine tests are still most effective for recent drug use within 5 days.

What it is, How it works

Hair analysis is increasingly regarded as an effective method for identifying alcohol and drug consumption. It captures enduring evidence of substance use by embedding biomarkers within the fibers of hair strands as they grow. When taken close to the scalp, hair might display substance usage for up to three months. Hair collection is straightforward, relatively hard to tamper with, and easy to transport.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp, amounts to 100mg, the optimal quantity for both screening and confirmation. For tests involving EtG, additional substances, or more than 10 panels, 150mg is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is inaccessible, an equal volume of body hair can be used. "Head hair" exclusively means scalp hair, while "body hair" encompasses other types like facial or axillary hair.

Process Overview

The lab processing of a drug test result follows four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the lab's system, ensuring the sample's seal and shipment are intact, a random Laboratory Accessioning Number (LAN) is assigned, and any remaining data entry not covered by an electronic chain of custody is completed.

Screening is a preliminary test to identify potential drug abuse. Although it is cost-efficient for negating drug use in most samples, a confirmed result is necessary for legal acceptability, requiring samples that indicate a positive result in Screening to undergo further verification.

If Screening shows a presumptive positive, additional hair is extracted and prepared for further analysis in Extraction. At this point, drugs are extracted from hair at significantly lower concentrations than other methods like urine or oral fluids, underscoring the complexity of hair drug testing.

Verification of any positive screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any initial positive samples are cleansed before confirmation if necessary. The entire process, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair designation and accreditation under ISO/IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can detect drug usage for up to 90 days, as opposed to urine tests with more limited detection spans.
  • Hard to manipulate: Cheating on a hair drug test is highly challenging, providing more reliable results.
  • Historical data provision: It offers insight into drug use patterns over time, beyond just recent intake.

Limitations:

  • Inability to detect recent use: Detection in hair starts around 5-7 days post-consumption.
  • Expenses: Hair drug testing is typically costlier than alternative drug testing procedures.
  • Result variability: Elements like hair pigmentation and personal variances in growth can influence drug metabolite levels detected in hair.

Note: Frequently termed "hair follicle tests," the procedure actually examines the strand, not the follicle beneath the scalp.

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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.

It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
