Hair Follicle Drug Testing - Milaca, MN

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol usage. Hair serves as a comprehensive record of alcohol and drug consumption by capturing biomarkers in the structure of the growing hair shaft. When obtained near the scalp, hair can reveal a detection period of up to around three months for alcohol and drugs. It is straightforward to collect hair samples, less prone to tampering, and easy to transport.

A sample of 1.5 inches consisting of about 200 hair strands (approximately the size of a #2 pencil) taken close to the scalp provides 100 mg, the optimal amount for analysis and verification. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150 mg is advised. We suggest measuring the sample with a jeweler's scale. If there is no scalp hair available, a similar amount of body hair can be gathered. When talking about head hair, we mean scalp hair specifically. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a laboratory's system. This step includes ensuring the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.

Screening entails a quick initial check for drugs of abuse. Although Screening is a cost-efficient way to exclude drug usage in most samples, a positive screen requires confirmation to be legally valid. Any samples that are tentatively positive in Screening need an additional confirmation.

If a sample appears positive during the Screening stage, additional hair is taken from the original sample for Extraction. In this phase, drugs are removed from the hair at a concentration much lower than other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging process.

The Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test tentatively positive are cleaned before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to evade: Cheating a hair drug test is very challenging, enhancing the reliability of the results.
• Displays historical patterns: It can show a trend of drug use over time, rather than just recent usage.

Limitations:

• Cannot detect immediate use: Approximately 5-7 days are needed for drugs to manifest in hair.
• Higher cost: Hair drug tests are typically more costly compared to other drug testing approaches.
• Result variability: Variables like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis is conducted on the hair strand, not the follicle under 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.
