Accredited Drug Testing offers thorough hair follicle drug testing services in Walnut Hill, Tennessee. When seeking drug or alcohol testing using hair samples, our expertise ensures accurate results, with centers available nationwide to perform these tests. A required hair length of 1.5 to 2 inches is sufficient for analysis, whether from the head or body, to test for drugs, alcohol/ETG, or other tailored testing needs.

Hair follicle drug tests have become increasingly popular for drug testing in recent years. Many employers, judicial systems, and substance abuse experts prefer hair drug testing over urine samples. Employers with a strict anti-drug policy, courts, and individuals on probation rely on this test. The key advantage is its extended detection timeframe of up to 90 days, with an observed collection process, making it highly reliable. Despite this, urine tests remain accurate for detecting recent drug use within the last five days.

What it is, How it works

Hair testing has evolved into a robust method for identifying drug and alcohol consumption. Hair acts as a long-term record of alcohol and drug use by embedding biomarkers within the strands of growing hair. When collected near the scalp, hair offers up to a roughly 3-month detection window for alcohol and drug analysis. Hair is straightforward to collect, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment comprising about 200 hair strands (approximately the width of a #2 pencil) near the scalp provides 100mg of hair, considered optimal for screening and confirmation tests. For EtG assessments, add-ons, and/or beyond 10-panel tests, a sample of 150mg is advisable. It is suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be obtained. When referencing head hair, it pertains exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial intake of a sample into the lab’s system. This process ensures that the sample is properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any leftover data entry not provided by an electronic chain of custody system.

Screening provides an initial cursory check for drugs of abuse. Although Screening offers a cost-efficient way to rule out drug presence in most samples, any positive findings require confirmation for legal admissibility. Samples showing presumptive positives in Screening necessitate further confirmation.

Upon a presumptive positive result from the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In Extraction, drugs are drawn from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most complex technique to execute.

Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing as necessary before confirmation. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

  • Extended detection timeframe: Hair drug tests trace drug use back up to 90 days, unlike urine tests which cover shorter periods.
  • Hard to manipulate: Cheating a hair drug test is exceedingly difficult, resulting in more reliable outcomes.
  • Offers historical perspective: It reveals drug use patterns over time rather than just recent activities.

Limitations:

  • Inability to detect immediate use: Drugs become detectable in hair after roughly 5-7 days.
  • Expense: Hair drug tests tend to be pricier than other drug testing strategies.
  • Result variability: Influences such as hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests", the analysis focuses on the hair strand itself, 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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.

In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.

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.
