Hair Follicle Drug Testing - Greenville, NC

What it is, How it works

Hair testing has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair entraps biomarkers within the fiber of the strand as it grows, offering a long-term record of substance use. By taking a sample near the scalp, it can reveal drug and alcohol presence within a time frame of roughly three months. Collecting hair is straightforward, tough to tamper with, and convenient to send off.

A segment measuring 1.5 inches with approximately 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg—ideal for both initial screening and confirmation processes. For EtG, additional tests, or panels exceeding ten, a 150mg sample is advisable. Use a jeweler’s scale to verify the weight. If scalp hair isn't accessible, equivalent body hair may be used instead. 'Head hair' pertains solely to scalp hair, whereas 'body hair' includes all other types (e.g., facial, axillary).

Process Overview

The drug testing procedure in labs is segmented into four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the preliminary step of integrating a sample into a lab’s framework. It encompasses ensuring the sample’s seal and shipment integrity, allocating a random LAN (Laboratory Accessioning Number), and completing any missing data entry absent from an electronic chain of custody.

Screening acts as an initial and swift check for substance misuse. Though cost-efficient for filtering out drug usage in most instances, a positive screen necessitates confirmation to be legally valid. Samples marked as presumptively positive during Screening must undergo further confirmation.

Following a presumptive positive at the Screening stage, more of the original sample is prepared for the Extraction phase. Drugs are derived from hair in considerably lower concentrations than with methods like urine or oral fluid, making hair drug screening exceptionally challenging.

Positive screenings undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Necessary prescreens labeled as positive are washed before confirmation. The entire transition from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage for up to 90 days, unlike urine tests with shorter detection ranges.
• Hard to manipulate: The robustness against manipulation increases result reliability.
• Traces usage history: Offers insights into drug use patterns over an extended duration, beyond just recent activities.

Limitations:

• Incapable of detecting recent use: It requires about 5-7 days for drug traces to manifest in hair.
• Expense: Hair drug tests entail higher costs compared to other methods.
• Outcome variations: Elements like hair hue and personal hair growth rates may influence metabolite concentrations.

Note: Although termed "hair follicle tests", the procedure evaluates the hair strand itself, 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.
