Accredited Drug Testing provides comprehensive hair follicle drug testing services in Marinwood, California. Specializing in hair analysis, we have testing facilities in every city across the nation capable of conducting these tests. Typically, 1.5 to 2 inches of hair is needed from the head or body. These tests can detect drugs, alcohol/ETG, or offer other tailored hair analysis options.

In recent times, hair follicle drug tests have become increasingly prevalent in drug testing procedures. Employers, judicial systems, and substance abuse professionals often prefer hair tests over traditional urine tests. Hair tests are crucial for organizations with zero-tolerance drug policies and legal or probation scenarios. A key advantage is the extended detection timeline of up to 90 days, collected under supervision, and highly tamper-resistant, unlike urine tests, which are more accurate for recent drug use within five days.

What it is, How it works

Hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline for alcohol and drug detection by encapsulating biomarkers in the fibers of the growing hair. When cut near the scalp, hair can deliver around a 90-day detection period for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and easy to send.

A strand sample of 1.5 inches with roughly 200 hairs (about the diameter of a #2 pencil) adjacent to the scalp provides 100mg, the recommended amount for both testing and confirmation. For tests like EtG, supplementary add-ons, or those exceeding 10 panels, 150mg of hair is advised. It is recommended to use a jeweler’s scale for measuring the specimen. If scalp hair is absent, an equivalent amount of body hair can be acquired. In describing head hair, we refer solely to scalp hair. Body hair includes all other hair types (e.g., facial and axillary).

Process Overview

The four primary stages in processing laboratory drug test results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial sample processing into the lab’s system. This step involves checking that the sample remains sealed and is shipped properly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not included in an electronic chain of custody process.

Screening facilitates an initial swift assessment for drugs. While cost-effective for initial screening across many samples, a positive screening outcome needs confirmation for legal admissibility. Samples that test presumptively positive require a follow-up confirmation.

Presumptive positives in Screening lead to further hair being extracted and prepped for Extraction. This stage involves separating drugs from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug screening is one of the most intricate methods.

Confirmation for any positive screening result utilizes techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation if necessary. The laboratory workflow from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair protocol and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a shorter timeframe.
  • Hard to falsify: It is challenging to falsify a hair drug test, therefore results tend to be more reliable.
  • Provides use history: Offers a view of drug usage patterns over time, not solely recent use.

Limitations:

  • Limited in detecting recent use: It takes roughly 5-7 days for drugs to be traceable in hair.
  • Expense: Hair drug tests are usually costlier compared to other testing approaches.
  • Result variations: Elements like hair color and personal hair growth rates can influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the testing process examines the hair strand rather than the scalp's hair follicle

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.

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. Results are provided in a form that can be reviewed by legal and administrative authorities.
