Hair Follicle Drug Testing - Vancleave, MS

What it is, How it works

Hair analysis is now acknowledged as an effective means to detect drug and alcohol consumption. The hair captures a comprehensive timeline of a person's intake by securing biomarkers within its strands as it grows. When hair is extracted close to the scalp, it can offer up to a three-month detection scope for alcohol and various drugs. Collecting hair is straightforward, somewhat hard to tamper with, and simple to send off.

A sample measuring 1.5 inches, consisting of roughly 200 strands of hair (akin to the thickness of a #2 pencil), near the scalp yields 100mg, which is the perfect sample for both screening and verification. For tests like EtG, additional analyses, and panels exceeding 10, it's advised to use 150mg of the sample. It's recommended to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be collected. When mentioning head hair, we mean exclusively scalp hair. Body hair includes all other hair types (such as facial and axillary).

Process Overview

The laboratory drug test result processing includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into the laboratory's framework. This step verifies that the sample is appropriately sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and carries out any additional data input absent from an electronic chain of custody system.

Screening consists of an initial rapid analysis for prohibited substances. While Screening offers an economical method to dismiss drug usage in most cases, confirmation is necessary for a positive screen to stand up legally. Samples showing presumptive positive results during Screening must undergo further confirmation.

Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the original sample in preparation for Extraction. During Extraction, drugs are isolated from hair, albeit at a lower concentration than with other methods (such as urine or oral fluid), which explains why hair drug testing is among the most complex methods.

Confirmation of any positive Screening result is performed with GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive undergo washing prior to Confirmation as required. Throughout the laboratory process, from Accessioning to Confirmation, evaluations are conducted under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection phase: Hair drug tests can trace drug use back up to 90 days, offering a longer window than urine tests.
• Tough to manipulate: Cheating on a hair drug test is quite difficult, thus the results tend to be more reliable.
• Historical evidence: It provides a timeline of drug use, documenting patterns rather than merely recent use.

Limitations:

• Recent intake detection: It requires approximately five to seven days for drugs to be traceable in hair.
• Expense: Hair drug testing typically costs more than other drug detection techniques.
• Result variations: Influences such as hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Commonly dubbed "hair follicle tests", the test inspects the hair strand rather than 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.
