Accredited Drug Testing offers comprehensive hair follicle drug testing services in Chappell Hill, Texas. Should you require a hair drug or alcohol test, Accredited Drug Testing is a specialist in hair testing with centers nationwide, offering services across all cities. Generally, 1.5 to 2 inches of hair from the crown or body is needed. Tests can screen for drugs, alcohol/ETG, or other tailored options.

The trend for drug testing has increasingly included hair follicle tests in recent years. Many employers, legal systems, and professionals in Substance Abuse fields prefer hair drug testing over the traditional urine tests. Employers with zero-tolerance policies, courts, and probation mandates use these tests due to their longer detection period, which spans up to 90 days, administered in a controlled manner to prevent tampering. However, urine tests remain the most precise for detecting usage within five days.

What it is, How it works

The utilization of hair testing is becoming recognized as an effective method for detecting drug and alcohol use. Hair captures a long-lasting record of alcohol and other drug consumption by embedding biomarkers within the fibers of the growing hair strand. When taken near the scalp, hair can provide a detection window of up to roughly 3 months for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample of 1.5 inches consisting of about 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. Utilizing a jeweler’s scale for weighing the sample is advisable. If scalp hair is not available, a similar amount of body hair may be used. The term 'head hair' pertains exclusively to scalp hair, whereas 'body hair' refers to all other hair types (facial, axillary, etc.).

Process Overview

The four key steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial introduction of a sample into the laboratory system. It involves ensuring the sample was sealed and delivered correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not supplied by an electronic chain of custody system.

Screening performs an initial rapid analysis for drugs of abuse. While Screening is cost-efficient for ruling out drug usage on the majority of samples, a positive result in the screen must be verified to be permissible in court. Any samples with a presumptive positive result in Screening require secondary confirmation.

Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at concentrations much lower than other methodologies (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
  • Challenging to falsify: Cheating a hair drug test is exceedingly difficult, ensuring more accurate results.
  • Offers historical usage data: It provides information on drug use patterns over time, not just recent usage.

Limitations:

  • Incapable of detecting recent usage: It requires about 5-7 days for drugs to become detectable in hair.
  • Expense: Hair drug tests are typically more costly than other drug testing methods.
  • Result variability: Factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although often termed as "hair follicle tests," the test itself examines the hair strand rather than the hair 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. 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.

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.
