Hair Follicle Drug Testing - Ostrander, MN

What it is, How it works

Hair analysis is recognized as a potent method for identifying drug and alcohol consumption. Hair retains a long-term record of substances in its fibers as it grows, capturing markers indicative of alcohol and drug use. By taking a sample close to the scalp, one can achieve a detection window of roughly three months for drugs and alcohol. Hair collection is straightforward, difficult to tamper with, and convenient for transportation.

A 1.5-inch section consisting of about 200 hair strands, roughly equating to a #2 pencil size, nearest the scalp provides 100mg of hair, the prime quantity for both screening and confirmation tests. For EtG, additional tests, or assessments exceeding 10 panels, 150mg of the sample is advisable. It's best to weigh the collected hair using a jeweler’s scale. In absence of scalp hair, a comparable amount of body hair can be taken. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The key phases in lab processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial handling in the lab’s system. The process includes ensuring the sample's proper sealing and shipment, allotting a random LAN (Laboratory Accessioning Number), and completing any manual data input absent in an electronic chain of custody system.

Screening serves as a quick preliminary test for drug presence. Although being a cost-effective method to exclude drug usage in most samples, any positive screen needs confirmation to be legal in court. Samples that test presumptively positive in Screening necessitate a further confirmation step.

If Screening suggests a positive result, additional hair is extracted from the initial sample and processed for Extraction. In this phase, substances are isolated from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging to execute.

Confirmation for any positive results from Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All initially positive samples are cleansed before confirmation as required. The whole lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and reaches the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests identify drug usage up to 90 days prior, whereas urine tests have a much shorter range.
• Challenge in falsification: Hair drug tests are notably hard to falsify, enhancing result reliability.
• Offers usage history: It presents a historical pattern of drug consumption over time, beyond recent use.

Limitations:

• Inability to detect recent use: Drugs require approximately 5-7 days to become detectable within hair.
• Expense: Typically, hair drug tests cost more than other drug testing options.
• Result variability: Differences such as hair color and personal hair growth rates can influence drug metabolite levels in the hair.

Note: Commonly called "hair follicle tests", these tests actually examine the hair strand instead of 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.
