Hair Follicle Drug Testing - Round Lake, MN

What it is, How it works

Hair analysis is now regarded as a significant technique for identifying substance and alcohol consumption. The hair encapsulates a long-term record of alcohol and drug use through biomarkers ensnared in the strands of the elongating hair. When gathered near the scalp, hair can offer roughly a 3-month lookout period for the presence of alcohol and narcotics. Hair collection is straightforward, relatively immune to tampering, and simple for transport.

A sample measuring 1.5 inches comprising about 200 hair strands (approximately the thickness of a #2 pencil) adjacent to the scalp will yield 100mg of hair, the optimal amount for both examination and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. If hair from the scalp is not available, an equivalent quantity of body hair may be obtained. When talking about head hair, it refers specifically to scalp hair. Body hair denotes all other types (e.g., facial, axillary).

Process Overview

The primary steps in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample inside a laboratory’s records system. This encompasses confirming the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by an electronic chain of custody setup.

Screening executes an initial rapid inspection for substances of abuse. This step is a budget-friendly means to dismiss drug engagement in most samples, yet a positive screening result must be affirmed to be valid in judicial settings. Any samples yielding a preliminary positive in Screening necessitate a further confirmation round.

Where a sample reveals a preliminary positive during the Screening phase, extra hair is drawn from the original sample for the Extraction phase. Here, substances are extracted from hair at notably lower concentrations unlike in other strategies (such as urine or oral fluids), underlining why hair drug screening is a more complex strategy to administer.

Affirmations of any positive screening outcome occur via GC/MS, GC/MS/MS or LC/MS/MS. All initial positive samples are cleansed before confirmation when required. The full laboratory operation from Accessioning to Confirmation undergoes review following both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Sustained detection period: Hair drug exams can reveal drug consumption up to about 90 days, unlike urine tests with a shorter timeframe.
• Cheating prevention: It's exceedingly tough to deceive a hair drug evaluation, rendering the outcomes more reliable.
• Reveals usage patterns: Capable of illustrating a timeline of substance use over an interval, not just recent consumption.

Limitations:

• Limited recent usage detection: Detection in hair requires approximately 5-7 days post usage.
• Expense: Generally, hair drug assessments cost more compared to other testing approaches.
• Result fluctuations: Variables like hair color and individual hair growth rates can influence drug metabolite concentration in the hair.

Note: Although frequently termed as "hair follicle tests", the evaluation is conducted on the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Round Lake, MN, hair follicle testing outshines traditional urine tests. With superior detection accuracy, hair testing remains reliable over a longer period.

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.
