Hair Follicle Drug Testing - Saint Cloud, MN

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by enclosing biomarkers in the strands of the growing hair. When sampled near the scalp, hair can offer a detection window of up to around 90 days for alcohol and drugs. Collecting hair is straightforward, relatively challenging to tamper with, and convenient to transport.

A 1.5-inch cut of about 200 hair strands (comparable to the thickness of a #2 pencil) from closest to the scalp will yield 100mg of hair, which is the preferred sample for examination and verification. For EtG, additional tests, or panels exceeding 10, a specimen weight of 150mg is advisable. Measuring the specimen using a jeweler’s scale is suggested. If scalp hair is unavailable, a commensurate amount of body hair may be obtained. By head hair, we mean scalp hair exclusively. Body hair refers to all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test outcomes consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial handling of a sample into a lab’s records. This process ensures that the sample was correctly sealed and dispatched, assigns a random Laboratory Accessioning Number (LAN), and completes any outstanding data entry that an electronic chain of custody system doesn’t cover.

Screening offers a preliminary rapid analysis for drugs of abuse. Although Screening provides a cost-efficient method to eliminate drug use in most samples, a positive screen must be validated to be legally acceptable. Any samples that exhibit a presumptive positive in Screening demand further confirmation.

Should a sample demonstrate a presumptive positive during Screening, additional hair is collected from the original specimen and readied for Extraction. In this phase, drugs are retrieved from the hair at a concentration much lower than other methods (such as urine or saliva), making hair drug analysis the most challenging method to conduct.

For any positive screening results, the Confirmation is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing a presumptive positive are cleaned before confirmation as required. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 benchmarks.

Strengths of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which cover a shorter duration.
• Resistance to tampering: Hair drug tests are exceptionally difficult to manipulate, resulting in more precise results.
• Reveals usage patterns: It delivers an overview of drug use over a specified duration, beyond just recent indulgence.

Drawbacks:

• Incapacity to detect recent consumption: Drugs become detectable in hair after approximately 5-7 days post-use.
• Higher cost: Hair drug tests are usually more costly compared to other drug testing options.
• Outcome fluctuations: Differences such as hair color and individual hair growth rates can influence drug metabolite concentrations in the hair.

Note: Frequently termed as "hair follicle tests," the analysis is conducted on the hair strand, 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.
