Hair Follicle Drug Testing - Lake Winola, PA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair offers a long-term record of alcohol and drug intake by holding biomarkers within the hair's growing strands. When obtained near the scalp, hair can provide up to a 3-month detection period for alcohol and drugs. Collection is straightforward, it is resistant to tampering, and shipment is easy.

A sample size of 1.5 inches consisting of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or tests over 10 panels, a sample of 150mg is advisable. Use a jeweler’s scale to measure the specimen. If scalp hair is not available, a similar quantity of body hair may be used. Head hair specifically refers to scalp hair only. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial step where a sample is processed into the laboratory's system. It involves checking the integrity of the sealed and shipped sample, allocating a random Laboratory Accessioning Number (LAN), and completing any necessary data entry absent from an electronic chain of custody system.

Screening provides an immediate overview of drug misuse. Although cost-efficient for ruling out drug use in most samples, a positive screening needs confirmation for legal acceptance. Presumptive positive results in Screening require secondary verification.

For presumptive positives from the Screening phase, additional hair is taken from the original sample for Extraction. In this phase, drugs are retrieved from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), which is why hair drug testing is noted for its complexity.

For confirming any positive screening outcome, GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed. Before confirmation, all presumptive positives are washed as necessary. The entire lab process, from Accessioning through Confirmation, undergoes evaluation under both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection window: Hair tests can reveal drug use up to 90 days, whereas urine tests have a shorter timeframe.
• Integrity: Due to the difficulty in cheating, hair tests yield more reliable results.
• Historical insight: It can outline a timeline of drug use over an extended period, as opposed to recent use.

Limitations:

• Inability to detect recent usage: Drugs take about 5-7 days to become traceable in hair.
• Expenses: Hair drug tests are generally pricier than other testing methods.
• Result variability: Aspects like hair color and individual hair growth rates can influence the concentration of drug metabolites within the hair.

Note: While commonly termed as "hair follicle tests," the analysis actually examines the hair shaft, 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.
