Hair Follicle Drug Testing - Riva, MD

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. The fibers of growing hair strands capture biomarkers, creating a detailed history of drug and alcohol use over time. Hair collected close to the scalp can offer a detection range of up to about three months for both alcohol and drugs. It is easy to collect, relatively resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, roughly the thickness of a #2 pencil and consisting of about 200 hair strands, will yield 100mg of hair, which is the recommended quantity for screening and confirmation. For EtG tests, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent volume of body hair can be gathered. 'Head hair' refers specifically to scalp hair, while 'body hair' encompasses all other types, including facial and axillary hair.

Process Overview

The laboratory processing of drug test results follows these four key procedures: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab's system. This step checks that the sample was correctly sealed and shipped, generates a random LAN (Laboratory Accessioning Number), and completes any necessary data entry absent from an electronic chain of custody system.

Screening performs an expedited preliminary assessment for drug presence. Although Screening is an economical method to rule out drug use in most samples, courts require confirmation of positive screens for legal admissibility. Any samples that test presumptively positive during Screening must undergo a follow-up confirmation.

Should a sample test presumptively positive in Screening, additional hair is extracted from the initial sample and prepared for Extraction. During Extraction, drugs are separated from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug analysis is regarded as one of the more intricate methodologies.

Confirmation for any positive result from initial Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples preliminarily testing positive are washed before confirmation if necessary. The complete laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and maintains ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug use up to 90 days into the past, unlike urine tests, which offer a shorter detection period.
• Hard to manipulate: Hair drug tests are difficult to falsify, leading to more dependable results.
• Presents historical data: It reveals a behavioral trend of drug consumption over an extended timeframe, not merely recent activities.

Limitations:

• Inability to detect recent use: It takes roughly 5-7 days for drugs to become measurable in hair.
• High cost: Hair drug tests tend to be more costly than alternative testing procedures.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite levels found in hair.

Note: Commonly known as "hair follicle tests", the test actually examines 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.
