Hair Follicle Drug Testing - Selma, NC

What it is, How it works

Hair testing is perceived as an effective means for identifying drug and alcohol usage. Hair captures a prolonged history of substance use by ensnaring biomarkers within the strands of hair as it grows. When gathered near the scalp, hair offers up to roughly a 3-month detection span for alcohol and drugs. Hair collection is straightforward, somewhat hard to tamper with, and convenient for shipping.

A sample measuring 1.5 inches with around 200 hairs (approximately the thickness of a #2 pencil) from the scalp provides 100mg, the optimal quantity for testing and verification. For EtG, additional tests or those beyond 10 panels, a quantity of 150mg is preferred. It is advised to weigh the specimen using a jeweler’s scale. Where scalp hair is absent, a comparable amount of body hair can be gathered. Scalp hair pertains to head hair, while body hair refers to other types (facial, axillary, etc.).

Process Outline

The essential phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into a lab’s system. This process checks that the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not covered by an electronic chain of custody system.

Screening involves a preliminary fast assessment for drug abuse. While cost-effective, the Screening phase needs a secondary confirmation for any positively screened sample to ensure legal validity. All presumptive positive samples from Screening require verification.

If a sample turns up presumptively positive in Screening, additional hair is drawn from the sample and readied for Extraction. Here, drugs are isolated from the hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening difficult to conduct.

Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is inspected under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Hair drug tests are challenging to fool, resulting in more reliable outcomes.
• Historical insights: They provide a history of drug use over time, not merely recent usage.

Challenges:

• Incapable of identifying recent use: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug testing is typically more costly than alternative methods.
• Result variations: Factors like hair color and individual hair growth can influence drug metabolite levels in hair.

Note: Despite being often termed as "hair follicle tests", the analysis focuses on the hair strand rather than the underlying hair follicle.

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.
