Hair Follicle Drug Testing - Linganore, MD

What it is, How it works

Utilizing hair tests is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers in their fibers, offering a chronological record of substance use. By harvesting hair near the scalp, analysts can achieve a drug and alcohol detection timeframe of nearly 3 months. This method of collection is straightforward, relatively resistant to tampering, and efficient to transport.

A 1.5-inch hair sample, comprising roughly 200 strands (akin to the thickness of a #2 pencil) from the root, yields 100mg, which is optimal for initial and confirmatory tests. For EtG, extra assessments, or tests beyond 10 panels, a sample of 150mg is preferable. We advocate for using a jeweler’s scale for precise measurement. In the absence of scalp hair, an equivalent volume of body hair is acceptable. The term head hair specifically denotes scalp hair, whereas body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Procedure Summary

There are four pivotal phases in processing a laboratory drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses initiating the sample’s integration into a lab’s system, ensuring its seal and shipment integrity, generating a random LAN (Laboratory Accessioning Number), and filling in any ancillary data entries absent from an electronic chain of custody method.

Screening constitutes a rapid initial assessment for illicit drugs. Although cost-effective for excluding drug presence in most samples, a positive screening needs validation to hold legal credibility. Any sample with a presumed positive in Screening mandates a further confirmatory test.

When a specimen exhibits a presumptive positive during Screening, further hair is extracted from the original sample for the Extraction phase. This phase isolates drugs at significantly lower concentrations compared to other techniques (such as urine or oral fluids), underscoring the complexity of hair drug testing.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used to confirm any positive screening results. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The comprehensive lab method from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
• Resistance to tampering: Avoidance of manipulation increases test result reliability.
• Chronological substance use data: It reveals a drug use timeline, not merely recent consumption.

Drawbacks:

• No detection of recent use: Drugs become discernible in hair only after approximately 5-7 days.
• Expense: Hair drug tests are typically costlier than other testing approaches.
• Result variability: Factors like hair pigmentation and individual differences in hair growth can alter drug metabolite concentration in hair.

Note: Commonly called "hair follicle tests", the assessment evaluates the hair strand itself rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests are a clear winner in Linganore, MD due to their superior detection accuracy over traditional urine tests. They offer not just a longer detection window, but also increased reliability in results.

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.
