Hair Follicle Drug Testing - Mechanicsville, IA

What it is, How it works

Hair testing is increasingly viewed as a formidable method for identifying drug and alcohol use. It catalogues a lengthy record of substance consumption by embedding biomarkers within the hair strand during its growth. Collected near the scalp, hair can reveal up to a 3-month history of alcohol and drug use. Gathering hair is uncomplicated, relatively tamper-proof, and easily transportable.

A 1.5-inch segment containing about 200 hair strands (resembling the size of a #2 pencil) from the scalp yields 100mg, the preferred quantity for screening and verification. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advised. Measuring the hair on a jeweler’s scale is recommended. If scalp hair is unobtainable, an equivalent portion of body hair can be used. In this context, "head hair" implies only scalp hair. "Body hair" encompasses all other hair types (such as facial or axillary).

Process Overview

The procedure for processing a drug test result in a lab comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory's system. This step ensures the integrity of the sample's seal and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any needed data entry absent from an electronic chain of custody system.

Screening executes a preliminary assessment for illicit substances. While Screening is a cost-effective technique for reviewing the bulk of samples, a positive screen must be confirmed to be legally valid. Samples testing presumptively positive require further confirmation.

For samples deemed presumptively positive at the Screening stage, additional hair from the primary sample is used for Extraction. During this step, the concentration of drugs in hair is extracted far lower than that in other methods (such as urine or oral fluid), underlining the complexity of hair drug screening.

Confirmation of positive results follows via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are washed pre-confirmation if necessary. The end-to-end lab process, from Accessioning to Confirmation, is scrutinized both under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair assessments detect drug use for as long as 90 days, surpassing the shorter detection span of urine tests.
• Difficult to manipulate: Altering results of a hair drug test is challenging, thereby ensuring greater accuracy.
• Reflects drug use trends: Offers insight into patterns over an extended duration, rather than only recent intake.

Limitations:

• Incapable of identifying recent use: Drugs only become detectable in hair after approximately 5-7 days.
• Expense: Conducting hair drug evaluations is typically costlier than other testing techniques.
• Result variability: Elements like hair color and individual hair growth characteristics can influence drug metabolite levels within hair.

Note: Commonly termed as "hair follicle tests," the actual analysis involves the hair strand, 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.
