Hair Follicle Drug Testing - Minnetonka, MN

What it is, How it works

The practice of hair testing has emerged as an effective method for identifying the usage of drugs and alcohol. Hair can chronicle a prolonged history of substance intake by encapsulating biomarkers within the fibers of its growth. When obtained near the scalp, hair offers a detection window of up to three months for both alcohol and drugs. Hair is straightforward to gather, less susceptible to tampering, and convenient to transport.

A 1.5-inch segment comprising roughly 200 hairs (about the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for analysis and verification. In cases of EtG, supplementary tests, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale is suggested to weigh the specimen. If there is no scalp hair available, a similar amount of body hair may be utilized. References to head hair specifically pertain to scalp hair, whereas body hair covers other hair types, including facial and axillary.

Process Overview

The primary stages in the laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within a laboratory’s framework. This phase includes ensuring the sample's seal and shipment are intact, granting a random LAN (Laboratory Accessioning Number), and finishing any additional data input absent from the electronic chain of custody system.

Screening serves as a preliminary rapid examination for drugs of abuse. While Screening economically excludes drug use for most samples, a positive screen demands confirmation to be court-admissible. Any samples presumed positive in Screening necessitate secondary confirmation.

In instances of a presumptive positive during Screening, extra hair is taken from the initial sample and set for Extraction. During this phase, drugs are extracted from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening techniques.

GC/MS, GC/MS/MS, or LC/MS/MS are utilized for Confirmation of any positive screening results. Before confirmation, all presumptive positive samples undergo washing as required. The entire laboratory processing sequence from Accessioning to Confirmation is conducted under both CAP (College of American Pathologists) Hair classifications and ISO / IEC 17025 standard accreditations.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug testing can identify drug consumption for up to 90 days, in contrast to urine tests with shorter detection spans.
• Cheating resistance: It is considerably challenging to falsify a hair drug test, enhancing result accuracy.
• Historical data provision: It can illustrate a pattern of drug usage over time, not merely recent consumption.

Limitations:

• Inability to detect recent usage: Detecting drugs in hair takes about 5-7 days.
• Expense: Hair drug tests are generally costlier than other drug-testing techniques.
• Result variability: Factors such as hair color and individual hair growth differences can influence the drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests", the analysis is conducted on the hair strand rather than 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.
