Hair Follicle Drug Testing - Taylortown, NC

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. It provides an extensive historical record of drug and alcohol use by encapsulating biomarkers within the strands of growing hair. When gathered near the scalp, hair can offer a detection period of up to around three months for alcohol and various other substances. It is easy to collect, relatively difficult to tamper with, and convenient to transport.

A 1.5-inch segment containing approximately 200 hairs (equivalent to the size of a #2 pencil) closest to the roots provides 100mg of hair, which is the optimal sample size for both initial screening and subsequent confirmation. For tests including EtG, additional metrics, and/or those exceeding 10 panels, 150mg of hair is advised. Utilizing a jeweler’s scale is recommended for measuring the specimen. Should scalp hair be unobtainable, an equivalent volume of body hair may be collected. Head hair refers exclusively to scalp hair, while body hair encompasses all other types (e.g., facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial registration of a sample within a lab's framework. This process involves confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional information not captured by an electronic chain of custody system.

Screening serves as an initial assessment for substances of abuse. Although it provides a cost-efficient means to eliminate most instances of drug use, a positive outcome requires confirmation to be legally valid in judicial contexts. Any presumptively positive samples during Screening require subsequent validation.

Should a sample show presumptive positivity in the Screening phase, further hair is extracted from the original sample for the Extraction phase. Drugs are extracted at significantly lower concentrations than in alternative methodologies (e.g., urine or oral fluid), positioning hair drug testing as the most challenging method to execute.

Positive screening results are verified through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are cleaned before confirmation if needed. Every step, from Accessioning to Confirmation, is vetted under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify substance use for up to 90 days, in contrast to urine tests that have a narrower detection window.
• Challenges in evasion: Evading a hair drug test is extremely challenging, ensuring higher accuracy of results.
• Historical insight: These tests can reveal patterns of substance use over time, not merely recent usage.

Limitations:

• Inability to detect recent use: It typically requires about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than other testing methodologies.
• Result variability: Variables like hair color and unique growth patterns can influence drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", the analysis targets the hair strand rather than 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.
