Hair Follicle Drug Testing - Windham Springs, AL

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage. By capturing biomarkers within the fibers of the growing hair strand, hair offers a prolonged record of alcohol and other substances. When collected near the scalp, hair can reveal evidence of alcohol and other drugs for up to roughly three months. Hair samples are easy to obtain, challenging to tamper with, and simple to transport.

Gathering a 1.5-inch section consisting of roughly 200 hair strands (approximately the size of a standard #2 pencil) closest to the scalp yields 100mg of hair, which is an ideal sample size for screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen weight of 150mg is advised. It's recommended to measure the specimen on a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair is acceptable. When discussing head hair, we refer specifically to scalp hair. Body hair includes all other variations (e.g., facial, axillary).

Process Overview

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

Accessioning pertains to the initial incorporation of a sample into a laboratory system, ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and concluding any additional data entry not provided by an electronic chain of custody system.

Screening involves an initial rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug usage from the majority of samples, the validity of a positive result requires confirmation for legal proceedings. All samples that yield preliminary positive results in Screening necessitate further confirmation.

If Screening indicates a presumptive positive, additional hair is drawn from the original specimen for Extraction. At this stage, drugs are extracted from hair at significantly lower levels than other methods (such as urine or oral fluid), underlying the complexity of executing hair drug screening methodologies.

Verification of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed as necessary before confirmation. The full laboratory procedure from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, while urine tests have a briefer detection window.
• Difficult to falsify: Cheating a hair drug test is exceptionally challenging, leading to more reliable results.
• Offers historical insights: It can reveal a use pattern over time, not merely recent drug use.

Limitations:

• Cannot identify recent consumption: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally involve higher costs than other drug testing methods.
• Result variability: Differences in hair color and personal hair growth might influence the concentration of drug metabolites in the hair.

Note: Despite often being termed "hair follicle tests", the test analyzes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Windham Springs, AL, hair follicle testing outshines traditional urine testing regarding detection accuracy and reliability. Hair tests have an edge due to their ability to reveal a history of drug use over a longer period.

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.
