Hair Follicle Drug Testing - Modesto, IL

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair captures biomarkers in the strands' fibers, offering a long-term record of alcohol and drug history. When taken near the scalp, hair is capable of providing up to a three-month detection timeline for substances. Collecting hair is straightforward, relatively tamper-proof, and easily transportable.

A sample size of 1.5 inches with around 200 hair strands (equivalent to the thickness of a #2 pencil) taken nearest to the scalp delivers 100mg, which is the optimal quantity for analysis and validation. For tests like EtG and/or those exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample with a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair can be used. Head hair specifically refers to scalp offerings, while body hair includes all other sorts (facial, axillary, etc.).

Process Overview

The primary stages in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial stage of integrating a sample into the lab’s processes. This step involves confirming the sample's proper sealing and shipping, issuing a random LAN (Laboratory Accessioning Number), and completing additional data entry if missing from an electronic chain of custody system.

Screening consists of a preliminary assessment for drug presence. Although Screening is an economical method to dismiss drug usage in most samples, a positive result necessitates confirmation for court admissibility. Any presumptively positive results from Screening are subjected to a subsequent confirmation.

Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the primary sample for preparation in the Extraction stage. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing particularly challenging.

Confirmation of any positive Screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation as required. The complete lab procedure from Accessioning to Confirmation is assessed 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 period: Hair tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficult to manipulate: Cheating a hair drug test is quite challenging, enhancing result accuracy.
• Offers historical insight: It can illustrate a drug use pattern over time, beyond recent use.

Limitations:

• Incapable of identifying recent use: Drugs require roughly 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variations: Elements such as hair color and individual growth can impact drug metabolite levels in hair.

Note: The test often called "hair follicle tests" assesses the hair strand instead of 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. 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.
