Hair Follicle Drug Testing - Silesia, MD

What it is, How it works

Hair testing is regarded as a robust solution for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by capturing biomarkers within the fibers of the growing strand. When obtained near the scalp, hair can reveal up to a roughly 90-day detection span for alcohol and various drugs. Hair is easy to acquire, tough to falsify, and straightforward to send.

A sample measuring 1.5 inches, comprising around 200 hair strands (similar in size to a #2 pencil) closest to the scalp, produces 100mg of hair, which is the ideal sample for analysis and verification. For EtG appendages, and/or assessments above 10 panels, 150mg of the sample is advisable. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be gathered. When specifying head hair, it pertains exclusively to scalp hair. Body hair denotes all other hair types (e.g., facial, axillary).

Process Overview

The primary procedures in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab’s framework. This encompasses confirming that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid assessment for narcotics. While Screening is a budget-friendly method to eliminate drug use on most samples, a positive outcome in Screening must be corroborated to hold up in legal proceedings. Any samples that are tentatively positive in Screening require additional confirmation.

If a sample is assumed positive in the Screening phase, more hair is extracted from the original specimen and set for Extraction. Here, drugs are isolated from hair at a noticeably lower concentration compared to other techniques (e.g., urine or oral fluid), which is what makes hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleansed before confirmation when necessary. The entire lab procedure from Accessioning to Confirmation is assessed following both the CAP (College of American Pathologists) Hair specification and validation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for as long as 90 days, unlike urine tests which offer a shorter detection interval.
• Difficult to deceive: Manipulating a hair drug test is very challenging, ensuring more precise results.
• Offers historic information: It can depict a usage pattern over time, beyond just recent consumption.

Limitations:

• Cannot identify recent use: Drugs become noticeable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically pricier than other testing alternatives.
• Result variability: Variables such as hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: While often called "hair follicle tests", the analysis involves 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.
