Hair Follicle Drug Testing - Winterville, NC

What it is, How it works

Utilizing hair testing is increasingly recognized as a strong approach for identifying drug and alcohol consumption. Hair can reveal an extended history of alcohol and drug intake, capturing biomarkers within the hair strand’s fibers as it grows. When taken near the scalp, hair samples can offer a detection window of up to three months for alcohol and drugs. The collection of hair is straightforward, somewhat resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (similar in size to a #2 pencil) taken nearest to the scalp, will yield around 100mg of hair—this is the optimal sample size for both screening and confirmation. For EtG and additional tests exceeding 10 panels, 150mg of the sample is advised. We suggest verifying the sample weight using a jeweler’s scale. Should scalp hair be unobtainable, an equivalent volume of body hair may be sourced. References to head hair specifically indicate scalp hair. Body hair encompasses all other hair types (such as facial and axillary).

Process Overview

The laboratory procedure for processing a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed within a laboratory’s system. Steps involve ensuring the sample’s seal and shipment were properly executed, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.

Screening involves a preliminary check for drugs of abuse. This step is a practical way to initially exclude drug use in the majority of samples; however, a positive screening outcome requires confirmation to be legally acceptable. Samples that show presumptive positive results in Screening must undergo a secondary confirmation process.

In cases where a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this step, extracting drugs from hair occurs at a significantly lower concentration relative to other methods (such as urine or oral fluid), presenting challenges in hair drug screening execution.

Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes are washed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, compared to urine tests that provide a shorter detection timeframe.
• Difficulty to cheat: Cheating a hair drug test is exceptionally hard, which makes the results more reliable.
• Provides historical data: It can reveal a pattern of drug usage over time rather than just recent consumption.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Cost: Generally, hair drug tests incur higher costs than alternative drug testing methods.
• Variations in results: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although commonly termed as "hair follicle tests," these tests analyze the hair strand and 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.
