Hair Follicle Drug Testing - Allen, NE

What it is, How it works

Hair analysis is regarded as a robust method for identifying substance and alcohol consumption. The hair captures a historical record of drugs and alcohol by holding biomarkers within the strands as they grow. By collecting hair near the scalp, a detection period of up to three months for alcohol and drugs can be achieved. The retrieval of hair is straightforward, hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches of about 200 hair strands (comparable to the thickness of a #2 pencil) next to the scalp yields 100mg, an optimal amount for both initial screening and confirmatory testing. For assessments such as EtG, extended panel tests over 10 items, a 150mg specimen is advised. It is ideal to use a jeweler’s scale for specimen weighing. If scalp hair is absent, similar body hair amounts can be obtained. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing drug test results involves four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a specimen into the lab's system. This step ensures the sample was properly sealed and shipped, assigns a LAN (Laboratory Accessioning Number), and finalizes any extra data entry not covered by an electronic chain of custody.

Screening provides an initial assessment for potential drug misuse. Although cost-efficient for eliminating drug use in most samples, any sample yielding a positive in Screening requires confirmation to be accepted legally. Samples that show presumptive positives in Screening need additional confirmation processes.

When a sample tests presumptively positive during Screening, extra hair is extracted from the initial sample for the Extraction stage. Drugs are then isolated from hair at lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing is notably complex.

Positive screening findings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo a washing step before confirmation if required. The full lab process, from Accessioning to Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days, whereas urine tests cover a shorter timespan.
• Hard to manipulate: Hair drug tests are difficult to deceive, enhancing result accuracy.
• Tracks usage patterns: Offers insights into drug usage over time, beyond just recent intake.

Limitations:

• Lacks detection of recent use: Drugs become apparent in hair only after about 5-7 days.
• Expense: Hair drug testing is typically costlier than other methods.
• Result variability: Factors like hair color and personal growth rates can influence drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests," the analysis examines the hair shaft, 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.
