Accredited Drug Testing offers comprehensive hair follicle drug tests in Marshall, Illinois. If you need a hair drug or alcohol assessment, Accredited Drug Testing is your go-to for specialized hair analysis. We have testing sites across all major cities Nationwide to carry out reliable hair tests. Generally, you should have 1.5 to 2 inches of hair on your head or body, which may be used. Hair tests can detect drugs, alcohol/ETG, or other tailored options.

In recent times, drug testing increasingly involves hair follicle assessments. Numerous employers, judicial systems, and Substance Abuse specialists now mandate hair drug tests over traditional urine tests. Hair follicle tests are favored by organizations enforcing zero-tolerance drug policies, courts, and probation officers. Their primary advantage is a substantially longer detection span for substance use, generally up to 90 days, collected under observation, and nearly immune to tampering. For detections within the last 5 days, urine tests remain the most precise.

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol consumption. As hair grows, it captures biomarkers within its strands, providing an extended timeline of alcohol and drug use. When sampled near the scalp, a hair test offers a detection period of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and easily transported.

A sample measuring 1.5 inches, consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp, yields 100mg of hair, which is optimal for initial testing and verification. For EtG, supplemental tests, and/or assessments exceeding ten panels, a sample of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent portion of body hair can be used. Head hair specifically refers to scalp hair, while body hair includes all other types (such as facial or axillary hair).

Process Overview

The lab processing of a drug test follows four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with integrating a sample into a lab’s system. This step includes confirming the sample's secure sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and filling in any missing data not provided through a digital chain of custody.

Screening performs an initial examination for drug abuse indicators. It’s an economical method to exclude drug consumption for most samples; however, a positive screening must be validated for legal proceedings. Samples showing a presumptive positive in Screening necessitate further confirmation.

If Screening suggests a positive result, additional hair is extracted from the original sample for the Extraction process. In this phase, drug compounds are isolated from the hair at significantly lower levels than in other testing methods (such as urine or oral fluid), making hair drug analysis a challenging methodology.

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

Benefits of hair drug testing:

  • Extended detection period: Hair tests can trace drug usage over a 90-day span, unlike urine tests with shorter detection periods.
  • Challenging to deceive: Hair tests are tough to alter, ensuring more reliable outcomes.
  • Tracks usage patterns: Offers insight into drug consumption trends over time, not just recent usage.

Drawbacks:

  • Lacks recent use detection: Drugs become traceable in hair approximately 5-7 days after use.
  • Expense: Hair drug tests usually cost more than other testing approaches.
  • Result variations: Differences in hair traits like color and individual growth rates can impact drug metabolite concentrations.

Note: Commonly called "hair follicle tests," the procedure examines the hair shaft rather than the follicle below 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. 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.
