Hair Follicle Drug Testing - Choptank, MD

What it is, How it works

Hair tests are recognized as an effective means for identifying drug and alcohol consumption. The fibers in a growing hair strand capture biomarkers, providing a prolonged history of alcohol and drug presence. When sourced close to the scalp, hair can indicate alcohol and drug usage over approximately a 3-month timeframe. Its collection is straightforward, adulteration is relatively challenging, and shipping is convenient.

Acquiring a 1.5-inch segment containing about 200 strands of hair (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is considered the perfect sample size for both screening and confirmation. For EtG, additional tests, and/or analyses beyond 10 panels, a specimen weighing 150mg is advised. It's advisable to measure the specimen using a jeweler's scale. If scalp hair cannot be obtained, a similar quantity of body hair can be utilized. The term 'head hair' specifically denotes scalp hair, while 'body hair' encompasses various types such as facial and axillary hair.

Procedure Summary

The drug testing procedure in a laboratory can be broken down into four vital steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initiation of a sample's journey through the laboratory's system. This phase involves confirming the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and filling in any additional information absent from an electronic chain of custody system.

Screening acts as an initial swift assessment for substance abuse. Though cost-effective for most samples, a positive screening outcome must be confirmed to hold legal validity. Samples with presumptive positive results during Screening require secondary confirmation.

In cases of presumptive positive outcomes at the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In Extraction, drugs are extracted from hair at significantly lower concentrations than those in other methodologies (ex. urine or oral fluid), underscoring the complexity of performing hair drug screening.

Confirmation of positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive outcomes undergo a washing process before confirmation if necessary. The entire lab procedure from Accessioning through Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Hair Drug Testing Benefits:

• Extended Detection Period: Hair tests detect drug usage for up to 90 days, unlike urine tests with shorter detection windows.
• Cheat-resistant: Hair drug tests are highly resistant to tampering, ensuring precise results.
• Historical Patterns: They reveal drug usage over a duration rather than immediate use instances.

Drawbacks:

• Not Immediate Detection: Drugs typically become hair-detectable 5-7 days post-use.
• Expense: Hair tests can be costlier than alternative drug testing methods.
• Variable Outcomes: Drug metabolite concentrations in hair may be influenced by hair color and personal growth rates.

Note: Although commonly called "hair follicle tests", the analysis is conducted on 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.
