Hair Follicle Drug Testing - Washington, NC

What it is, How it works

Hair testing is now recognized as an effective method for detecting drug and alcohol consumption. The hair captures biomarkers of alcohol and drugs within the fibers of its growing strand, providing a timeline of use. When taken near the scalp, hair offers a detection period of up to about 3 months for alcohol and drugs. Hair is effortless to collect, hard to tamper with, and straightforward to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (akin to the diameter of a #2 pencil) taken from the scalp will yield 100mg, the optimal amount for screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, 150mg is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be used. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The drug test processing in the lab consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial step where a sample is processed into the lab’s system. It involves ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not provided by an electronic chain of custody system.

Screening is a quick initial check for drug misuse. While this is a cost-efficient method to exclude drug use in most samples, a positive finding must be confirmed to be valid in court. Samples presumptively positive in Screening require further confirmation.

If a sample is presumptively positive during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this stage, drugs are extracted from hair at notably lower concentrations compared to other methods (like urine or oral fluid), demonstrating why hair drug screening presents a methodologically challenging process.

Confirmation of any positive finding in screening is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The entire process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for a span of up to 90 days, whereas urine tests feature a shorter detection timeframe.
• High difficulty to falsify: Cheating a hair drug test is very challenging, ensuring more precise outcomes.
• Tracks historical data: It can outline a timeline of drug use, capturing patterns over time rather than only recent activities.

Limitations:

• Recent use undetectable: Drugs take roughly 5-7 days to become detectable in hair.
• Cost factor: Hair drug testing often incurs higher expenses than alternative drug testing methods.
• Result variations: Elements like hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: Although often called "hair follicle tests", the test assesses the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Washington, NC, hair follicle testing distinctly outshines traditional urine tests. Key benefits include superior detection accuracy over an extended period and reliability that urine tests often fail to provide. With hair testing, the window for detecting drugs lengthens, offering a broader scope for identifying substance use, which is invaluable for those keen on maintaining stringent drug-free environments.

Extended Detection Window

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.
