Hair Follicle Drug Testing - New Haven, MI

What it is, How it works

Hair analysis is increasingly recognized as an effective measure for identifying drug and alcohol consumption. Hair retains a prolonged record of drug and alcohol use by capturing biomarkers within the strands as they grow. When obtained close to the scalp, hair can yield a detection period of up to around three months for alcohol and other drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.

A 1.5-inch section containing about 200 hair strands (roughly equivalent to the thickness of a #2 pencil) from near the scalp provides 100mg of hair, the optimal sample size for initial screening and subsequent confirmation. For EtG testing, additional tests, or those exceeding 10 panels, a quantity of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. In cases where scalp hair is lacking, a comparable amount of body hair may be used. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of samples for drug testing consists of four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the primary task is to integrate a sample into the lab's database. This process involves confirming that the sample was properly sealed and shipped, generating a unique LAN (Laboratory Accessioning Number), and performing any additional data input that may not be covered by an electronic chain of custody system.

Screening entails an initial rapid assessment to detect drug misuse. While Screening serves as a cost-efficient method to exclude drug usage in many samples, a positive Screening result must be validated for legal standing. Any samples showing presumptive positives in Screening necessitate further confirmation.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the initial specimen and readied for Extraction. This phase involves extracting drugs from hair at a considerably lower concentration compared to other approaches (such as urine or oral fluid), which underscores the complexity of hair drug testing processes.

Any positive results in the screening phase are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positives undergo washing as required. The full laboratory workflow from Accessioning to Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair protocols and ISO / IEC 17025 accreditation criteria.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can reflect drug use over a 90-day period, unlike urine tests, which have a shorter detection timeframe.
• Resistance to tampering: Cheating a hair drug test is very challenging, enhancing the reliability of the results.
• Historical insights: Offers a record of drug use patterns over time, rather than just recent intake.

Drawbacks:

• Unable to detect recent consumption: Drugs become evident in hair only after about 5-7 days.
• Expense: Hair drug testing is typically more costly than other testing methods.
• Result variability: Characteristics like hair color and individual differences in hair growth can influence drug metabolite levels in the hair.

Note: Although often called "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle located 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.
