Hair Follicle Drug Testing - Weeki Wachee, FL

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair records a prolonged timeline of alcohol and drug use by locking in biomarkers within the growing hair fibers. When hair is collected near the scalp, it offers up to roughly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch section of about 200 hair strands (approximately the volume of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample size for screening and validating. For EtG, additional tests, or tests beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, an equal quantity of body hair is acceptable. When mentioning head hair, we specifically mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The four core steps of lab processing for a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial entry of a sample into a laboratory's system. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and enters any remaining data not covered by an electronic chain of custody.

Screening entails an initial rapid assessment for substances. While Screening is a cost-effective method to exclude drug usage in most samples, a positive outcome must be corroborated for legal acceptability. Samples that test presumptively positive in Screening necessitate another verification step.

If a sample is deemed presumptively positive during Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening the most complex method to conduct.

Confirmation of any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The complete lab process from Accessioning to Confirmation complies with the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation.

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 duration.
• Hard to manipulate: It is extremely challenging to alter results in a hair drug test, enhancing result accuracy.
• Historical insight: It provides a timeline of drug use over an extended duration, rather than just recent use patterns.

Limitations:

• Cannot identify recent use: It takes about 5-7 days for drug presence to be noticeable in hair.
• Expense: Hair drug tests tend to be more costly than other drug testing techniques.
• Result variability: Variables such as hair color and personal differences in hair growth might influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the test 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.
