Hair Follicle Drug Testing - Fredericksburg, IA

What it is, How it works

Hair analysis is viewed as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug use by capturing biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can reveal up to a 3-month detection period for alcohol and drugs. Hair is straightforward to collect, moderately challenging to tamper with, and easy to transport.

A 1.5-inch section of roughly 200 hair strands (comparable in size to a #2 pencil) next to the scalp yields 100mg of hair, the optimal sample size for analysis and verification. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for measuring the sample. If scalp hair is not available, an equivalent amount of body hair can be used. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning starts with the preliminary inclusion of a sample into a lab’s system. This comprises verifying that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not supplied by an electronic chain of custody system.

Screening is an initial rapid assessment for drug abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be confirmed for legal acceptance. Any samples that are perhaps positive in Screening do require additional confirmation.

If a sample is tentatively positive in the Screening stage, additional hair is taken from the initial sample and readied for Extraction. Here, drugs are removed from the hair at a lower concentration than other techniques (ex. urine or oral fluid), making hair drug screening the most challenging method to conduct.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples are cleaned before confirmation as needed. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can uncover drug use for up to 90 days, as opposed to urine tests which have a shorter detection span.
• Hard to deceive: It is quite difficult to deceive a hair drug test, providing more accurate results.
• Offers historical information: It depicts a pattern of drug use over time, not just recent use.

Limitations:

• Inability to detect recent use: It takes approximately 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: Elements like hair color and personal hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests", the test examines the hair strand and 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.

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.
