Accredited Drug Testing provides thorough hair follicle drug tests in Neva, Tennessee. Whether seeking a hair drug or alcohol test, our specialty at Accredited Drug Testing is hair analysis, with testing centers available in cities across the country. Typically, 1.5 to 2 inches of hair from your head or body suffices for testing. Hair evaluations can identify drugs, alcohol/ETG, and other tailored testing solutions.

Recently, using hair follicle drug tests has become more prevalent. Many firms, judicial systems, and Substance Abuse experts prefer a hair test over a conventional urine test. Employers with zero-tolerance drug policies, courts, and probationary programs often use these tests. The principal advantage of hair tests is a longer detection span—usually up to 90 days. These tests involve an observed collection, making them highly reliable. However, for recent drug use (within 5 days), urine tests remain the most precise option.

What it is, How it works

The use of hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Through the entrapment of biomarkers in the hair strands, hair analysis offers a comprehensive history of substance use. When hair is collected near the scalp, it can reveal up to a three-month record of alcohol and drug use. The collection process is straightforward, with minimal opportunities for tampering, and the samples are easy to send.

A 1.5-inch cut of about 200 hair strands (akin to a #2 pencil in thickness) near the scalp yields 100mg, which is the preferred volume for testing. To include EtG, additional panels, or tests exceeding 10 panels, a 150mg hair sample is advised. The specimen should be measured using a jeweler’s scale. In cases where scalp hair isn't accessible, the same volume from body hair can be utilized. Note that "head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types (facial, underarm, etc.).

Process Overview

The laboratory progression for processing a drug test result entails four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary processing of a sample into the lab's database. It involves confirming the sample's secure sealing and shipment, generating a unique LAN (Laboratory Accessioning Number), and fulfilling any further data entry requirements absent from an electronic chain of custody.

Screening serves as an immediate assessment for identifying substances of abuse. Although a cost-efficient method to exclude drug presence in most cases, a positive result during Screening necessitates validation for legal proceedings. Presumptive positives identified in Screening undergo secondary confirmation.

Upon a presumptive positive during Screening, additional hair is taken from the initial sample for Extraction preparation. In this phase, drugs are isolated from hair at significantly lower concentrations than found in other methods (e.g., urine or oral fluid), which underscores the complexity of performing hair drug tests.

Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as needed before Confirmation. The entire process, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair certification and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection timeframe: Hair drug testing identifies drug usage up to 90 days, unlike the shorter duration identified by urine tests.
  • Difficult to manipulate: Cheating a hair drug screening is challenging, enhancing result reliability.
  • Historical insight: It delineates a timeline of drug use over time, unlike tests that capture only recent consumption.

Limitations:

  • Delayed detection: It requires about 5-7 days post-use for drugs to be traceable in hair samples.
  • Expense: Hair-based drug testing generally incurs higher costs than alternative methods.
  • Result variability: Influences such as hair color and individual differences in hair growth rate can impact drug metabolite concentrations.

Note: Although commonly termed as "hair follicle tests," this testing evaluates the hair itself and not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Neva, TN, the debate between hair follicle and urine testing showcases key advantages of the former. Hair testing surpasses urine tests by offering a longer detection window and higher accuracy, making it a superior choice for those needing reliable and thorough screenings.

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.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. 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.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory.
