Hair Follicle Drug Testing - Judith Gap, MT

What it is, How it works

Hair testing is now recognized as an effective means for identifying drug and alcohol usage. Hair retains a long-term record of alcohol and drug intake by encapsulating biomarkers within the hair strand's fibers during growth. When fetched from near the scalp, hair offers an approximate 3-month detection timeframe for alcohol and drugs. It's easy to collect, hard to tamper with, and straightforward to transport.

A sample size of 1.5 inches containing around 200 hair strands (roughly the size of a standard #2 pencil) taken closest to the scalp will yield 100mg of hair, which is optimal for screening and confirmation tests. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. Should scalp hair be unavailable, an equal quantity of body hair may be utilized. Referring to head hair implies scalp hair only, while body hair includes facial, axillary, and other types.

Process Overview

The entire laboratory processing of a drug test result entails four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process dealing with the initial integration of a sample into the laboratory’s system. It includes ensuring the sample was appropriately sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry lacking from an electronic chain of custody system.

Screening offers an initial swift examination for drug misuse. While Screening is an economical approach to exclude drug use in most samples, a positive result requires confirmation for it to be legally acceptable. Any samples that yield a presumptive positive in Screening must undergo secondary confirmation.

If a sample receives a presumptive positive during Screening, additional hair is pulled from the original specimen and prepared for Extraction. In this phase, drugs are pulled from hair at substantially lower concentrations compared to other methods (like urine or oral fluid), making hair drug testing one of the most challenging methodologies to execute.

Confirmation for any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples are washed before confirmation if necessary. The complete laboratory cycle from Accessioning to Confirmation is conducted under the joint review of the CAP (College of American Pathologists) Hair designation and the authorization compliant with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests offer drug use detection for as long as 90 days, unlike urine tests that have a shorter detection window.
• Hard to fake: Hair drug tests are challenging to cheat on, leading to more reliable results.
• Displays historical patterns: It reveals a pattern of drug use over duration, rather than only recent use.

Limitations:

• Incapable of detecting recent use: Drugs need roughly 5-7 days to become identifiable in hair.
• Pricing: Hair drug tests are typically costlier than alternative drug testing methods.
• Result variability: Elements such as hair color and individual hair growth variations may influence drug metabolite concentrations in hair.

Note: Despite often being termed as "hair follicle tests", the test actually examines the hair strand, not 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.
