Hair Follicle Drug Testing - Kent Acres, DE

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair captures biomarkers within the strands as the hair grows, offering a prolonged history of substance use. When hair is collected near the scalp, it can reveal drug and alcohol usage for up to roughly three months. Hair collection is straightforward, relatively tamper-proof, and easily transportable.

A 1.5-inch hair sample consisting of around 200 strands (comparable to a #2 pencil) taken from the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to measure the specimen's weight using a jeweler's scale. In the absence of scalp hair, an equivalent amount of body hair is acceptable. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other types, including facial and axillary hair.

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory’s system. This step includes ensuring the sample’s proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry required beyond what the electronic chain of custody system provides.

Screening is an initial, rapid evaluation for the presence of drugs. Although Screening is a pragmatic approach to discount drug usage across most samples, a positive screen must undergo confirmation to be legally admissible. Samples that test presumptively positive during Screening necessitate further confirmation.

If a sample is preliminarily positive in the Screening phase, more hair from the initial sample is utilized for Extraction. At this stage, drugs are extracted from hair at lower concentrations compared to other methods like urine or oral fluid, making hair drug screening the most challenging to execute.

Confirmation of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation when required. The entire laboratory procedure from Accessioning to Confirmation is assessed under both CAP’s (College of American Pathologists) Hair designation and accreditation following ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug use for as long as 90 days, while urine tests have a shorter duration of detection.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, resulting in more reliable outcomes.
• Chronological data: It provides a timeline of drug use over a period rather than only recent use.

Limitations:

• Incapable of detecting recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Variability in outcomes: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations within hair.

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