Hair Follicle Drug Testing - Oak Hill, AL

What it is, How it works

Hair testing is increasingly viewed as a highly effective method for monitoring drug and alcohol consumption. By embedding biomarkers within the fibers of the hair strand as it grows, hair offers a comprehensive long-term record of substance use. When collected near the scalp, hair can reveal a detection period for drugs and alcohol lasting up to approximately three months. Collecting hair is straightforward, less prone to tampering, and easily transportable.

A sample of 1.5 inches, comprising about 200 strands of hair (roughly the diameter of a #2 pencil) closest to the scalp, will yield 100mg, the optimal amount for analysis. For EtG and additional tests beyond 10 panels, a sample weighing 150mg is preferred. We advise using a jeweler’s scale for accurate measurement. If scalp hair is not available, a similar quantity of body hair can be used. The term head hair specifically signifies scalp hair, while body hair includes all other types (face, underarm, etc.).

Process Overview

There are four key stages in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial phase where a sample is processed into the lab system. This phase checks that the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional necessary data entry outside of an electronic chain of custody system.

Screening entails an initial rapid test for commonly abused drugs. Although Screening is a cost-effective method for ruling out drug use in most samples, a positive Screening result requires confirmation before it is court-admissible. Any samples that may test positive in Screening necessitate further confirmation.

If a sample tests presumptively positive in the Screening phase, additional hair is retrieved from the initial sample and prepared for Extraction. During Extraction, drugs are isolated from hair at a much lower concentration than other methods (such as urine or oral fluid), contributing to the complexity of hair drug testing.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that test presumptively positive are washed before Confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing can identify drug use for up to 90 days, whereas urine tests have a shorter detection period.
• Harder to manipulate: Cheating a hair drug test is quite challenging, thereby enhancing result accuracy.
• Offers historical insight: It demonstrates a drug use trend over time, not just recent consumption.

Limitations:

• No recent use detection: Drugs become detectable in hair after roughly 5-7 days.
• Higher expense: Hair drug tests are often costlier than alternative testing methods.
• Result variability: Factors such as hair color and personal hair growth differences can influence the drug metabolite levels in hair.

Note: Typically known as "hair follicle tests", these tests actually analyze 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.
