Hair Follicle Drug Testing - Newtown, MD

What it is, How it works

Hair testing is regarded as an influential method for detecting drug and alcohol consumption. Hair captures a lengthy chronicle of alcohol and drug intake by trapping biomarkers within the structure of the hair strand as it grows. When acquired near the scalp, hair can reveal a detection span of approximately three months for alcohol and drugs. It is straightforward to collect, relatively resistant to adulteration, and convenient to transport.

A sample measuring 1.5 inches, consisting of around 200 strands of hair (roughly the circumference of a #2 pencil) closest to the scalp, yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or analyses exceeding 10 panels, a specimen of 150mg is advised. It is suggested to weigh the specimen on a jeweler's scale. Should scalp hair be inaccessible, a comparable quantity of body hair can be gathered. When mentioning head hair, it specifies only scalp hair. Body hair encompasses every other type of hair (such as facial, axillary, etc.).

Process Overview

The principal phases in the laboratory management of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a laboratory's system. This process confirms the sample was properly sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and supplements any lacking data entry not obtained via an electronic chain of custody system.

Screening performs an initial examination for drugs of abuse. Although cost-efficient for exonerating drug usage in most samples, a positive screen demands confirmation for judicial admissibility. Samples yielding presumptive positives in Screening necessitate further validation.

If Screening suggests a positive result, additional hair is retrieved from the initial sample set for Extraction. During this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening in execution.

Positive screening assertions are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives undergo washing as required before verification. The complete lab workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can ascertain drug use for up to 90 days, whereas urine tests offer a decreased detection period.
• Resistance to manipulation: Hair drug tests are notably difficult to falsify, enhancing the reliability of the outcomes.
• Offers historical insight: It provides a timeline of drug use over time, rather than merely recent utilization.

Limitations:

• Incapable of identifying recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests usually incur higher costs compared to other testing techniques.
• Result variability: Elements such as hair color and individual hair growth differences can influence drug metabolite concentration within hair.

Note: Although termed "hair follicle tests," the analysis targets the hair strand itself, excluding the hair 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.
