Hair Follicle Drug Testing - Stevens Point, WI

What it is, How it works

The use of hair testing as a means for identifying drug and alcohol consumption is increasingly recognized. Hair acts as a record keeper, storing markers of alcohol and drug use within the fibers of the growing strand. When collected near the scalp, hair samples can reveal drug and alcohol use over a period of up to three months. This method of collection is straightforward, less prone to tampering, and convenient to transport.

Collecting a 1.5-inch sample, containing roughly 200 hair strands (similar in size to a #2 pencil), yields about 100mg of hair, which is ideal for screening and confirmation. For enhanced screening such as EtG, add-ons, or tests beyond 10 panels, a 150mg sample is advisable. It's best practice to weigh the sample using a jeweler’s scale. Should scalp hair be unobtainable, a comparable amount of body hair can be submitted. Note that ‘head hair’ refers specifically to scalp hair, while ‘body hair’ includes all other categories of hair (e.g., facial and axillary).

Process Overview

The process for laboratory drug testing consists of four vital phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the specimen is introduced into the laboratory system. This involves confirming the sample's proper sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and completing any additional data entry not available from an electronic chain of custody.

Screening serves as an initial assessment for signs of drug use. While it is an affordable method for excluding drug presence in most samples, a positive result here must undergo confirmation for legal validity. Any sample that hints at drug presence during Screening requires further confirmation.

Should a sample show potential signs of drug use at the Screening phase, additional hair is sourced from the initial sample for Extraction. This phase involves extracting drugs at concentrations lower than other methods (like urine or oral fluid), making it a challenging testing methodology.

To verify any positive screening outcomes, GC/MS, GC/MS/MS, or LC/MS/MS techniques are applied. Prior to confirmation, samples with presumptive positives are cleansed as required. The comprehensive testing journey from Accessioning to Confirmation operates under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use up to 90 days back, surpassing the shorter window with urine testing.
• Hard to deceive: Due to the inability to easily cheat a hair drug test, results tend to be more reliable.
• Tracks usage history: It offers insights into drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to show in hair samples.
• Expense: Hair drug testing generally incurs higher costs compared to other methods.
• Result variability: Factors like hair color and individual hair growth differences can impact concentration levels of drug metabolites in hair.

Note: Despite being termed "hair follicle tests", the analysis pertains to the hair strand itself, 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.
