Accredited Drug Testing provides comprehensive hair follicle drug testing services in Purdin, Missouri. If a hair drug or alcohol test is needed, we specialize in hair testing with centers across the nation capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the scalp or body is used. Hair tests can screen for drugs, alcohol/ETG, or tailored options.

The use of hair follicle drug tests has grown in popularity for drug testing in recent years. Many employers, judicial systems, and Substance Abuse professionals are opting for hair drug tests instead of urine tests. Employers with zero-tolerance policies, courts, and those on probation often require hair follicle drug tests. The main advantage is the extended detection period, which is generally up to 90 days, gathered under observation, making it very difficult to manipulate. However, for screening recent drug use within 5 days, urine tests remain the most accurate.

What it is, How it works

Hair analysis is now regarded as a robust means of identifying substance and alcohol intake. Hair offers an extended historical record of alcohol and drugs by embedding biomarkers within the strands of growing hair. Collected near the scalp, hair can reveal up to a roughly three-month detection period for alcohol and drugs. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.

A 1.5-inch portion of about 200 hair strands (akin to a #2 pencil) closest to the scalp yields 100mg of hair, the ideal quantity for screening and verification. For EtG, additional tests, or tests beyond 10 panels, extending to 150mg of the sample is advised. Using a jeweler’s scale to measure the sample is recommended. If head hair is not obtainable, a comparable amount of body hair can be gathered. By head hair, we mean scalp hair only. Body hair includes any other hair types (facial, axillary, etc.).

Process Overview

The laboratory undertakes four primary steps in processing a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial handling of a sample in a lab’s system, verifying the sample was accurately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and performing any data input not covered by an electronic chain of custody system.

Screening entails a swift preliminary check for substance abuse. While screening offers a budget-friendly approach to exclude drug consumption in most cases, a positive result necessitates confirmation for legal acceptability. Samples rendered presumptively positive in screening necessitate a further confirmation.

Should a sample be tentatively positive during Screening, further hair is extracted from the original specimen and prepared for Extraction. Here, substances are extracted at significantly lower concentrations than in alternative methodologies (e.g., urine or oral fluid), which is why hair drug analysis remains a highly intricate methodology.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation as required. The entire lab process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug analysis:

  • Extended detection window: Hair drug analysis can identify drug use up to 90 days, unlike urine analysis which has a shorter detection timeframe.
  • Challenge to falsify: Cheating a hair drug test is remarkably difficult, ensuring more accurate results.
  • Historical data provided: It offers a historical perspective on drug use, not merely recent intake.

Drawbacks:

  • Inability to detect recent use: Drugs become detectable in hair in approximately 5-7 days.
  • Expense: Hair drug analyses are generally costlier than other methods.
  • Inconsistent outcomes: Factors like hair coloration and personal differences in hair growth might influence drug metabolite concentrations.

Note: Though referred to as "hair follicle tests", the test examines the hair 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.

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.
