Accredited Drug Testing provides comprehensive hair follicle drug testing across Coastal, California. If a hair drug or alcohol test is required, our expertise is in hair testing, with available testing centers in every city nationwide capable of performing this test. Typically, 1.5 to 2 inches of hair from your head or body are necessary. Hair tests can be utilized to check for drugs, alcohol/ETG, or tailored hair testing options.

In recent years, a shift towards using hair follicle drug tests for drug detection has been evident. Employers, courts, and Substance Abuse professionals now often mandate a hair drug test over the traditional urine test. Hair follicle tests are favored by employers with zero-tolerance drug policies, courts, and those on probation. They boast a key advantage: a considerably longer detection period of up to 90 days, with observed sample collection, making them particularly hard to manipulate. Nevertheless, for detecting drug use within the last 5 days, urine tests remain the most precise option.

What it is, How it works

The detection of drugs and alcohol through hair testing is recognized as an effective method. Hair strands capture the history of alcohol and drugs over time by encasing biomarkers in their fibers during growth. When sampled near the scalp, hair can offer a detection period for alcohol and drugs of up to about 3 months. It is straightforward to collect, relatively hard to tamper with, and straightforward to transport.

Collecting a 1.5-inch segment containing approximately 200 strands (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For testing such as EtG or panels above 10, a sample of 150mg is advised. Using a jeweler’s scale for weighing is suggested. If scalp hair is not an option, a similar quantity of body hair may be used. In this context, head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the step where a sample is initially processed into a laboratory's system. This involves confirming that the sample is correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any remaining data entry absent in an electronic chain of custody system.

Screening entails an initial rapid check for substances of abuse. Although Screening efficiently rules out drug use in most samples, a positive Screening requires confirmation to hold in court. Any presumptive positives in Screening necessitate an additional confirmation step.

If a sample shows presumptive positivity in Screening, additional hair from the original sample is prepared for Extraction. This phase aims to extract drugs from hair, which occurs at lower concentrations compared to methods such as urine or oral fluid tests, highlighting the complexity of hair drug screening.

Confirmation of positive Screening results is performed using GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples presumptively positive are washed prior to confirmation where necessary. The entire process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Long detection window: Hair drug tests can detect drug use for up to 90 days, surpassing the shorter window of urine tests.
  • Difficulty to cheat: Cheating a hair drug test is inherently challenging, ensuring more reliable results.
  • Provides historical data: It reveals a timeline of drug use, rather than solely focusing on recent consumption.

Limitations:

  • Cannot detect recent use: Detected drugs in hair take about 5-7 days to become apparent.
  • Cost: Hair drug tests generally incur higher costs compared to other testing techniques.
  • Variations in results: Variables like hair color and individual hair growth rates can influence metabolite concentration in hair.

Note: Despite the common term "hair follicle tests," the analysis is conducted on the hair strand and not on 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.

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.
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.
