Hair Follicle Drug Testing - Chadds Ford, PA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug use, capturing biomarkers within the strands of the hair as it grows. When taken close to the scalp, a hair sample can offer up to a 3-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, comprising around 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the preferred sample size for screening and verification. For tests like EtG, extended panels, and those exceeding 10 panels, a specimen size of 150mg is advisable. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair might be used. When referencing head hair, it specifically means scalp hair. Body hair includes all other kinds of hair (facial, underarm, etc.).

Process Overview

The four primary stages in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial intake of a sample into a laboratory's system. This process ensures that the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and performs any further data entry not captured through an electronic chain of custody.

Screening is a preliminary assessment for signs of drug abuse. While it is an economical approach to identify drug usage for most samples, a positive result needs confirmation to be validated in court. Any samples that test positive during Screening must undergo a secondary confirmation.

Should a sample test positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. During Extraction, drugs are extracted from hair at significantly lower concentrations than other methods like urine or oral fluid, making hair drug testing one of the most challenging methodologies to execute.

Confirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation 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 timeframe.
• Difficult to manipulate: Cheating on a hair drug test is extremely challenging, increasing the accuracy of the results.
• Shows usage trends: It provides a record of drug use over time, not solely recent consumption.

Limitations:

• Unable to detect recent consumption: It takes about 5-7 days for drugs to be found in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence the drug metabolite concentration in the hair.

Note: Despite being frequently called "hair follicle tests", the test is conducted on the hair strand and not on 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.
