Hair Follicle Drug Testing - Greater Northdale, FL

What it is, How it works

Hair testing has emerged as a formidable method for uncovering substance use. By capturing biomarkers within the fibers of a growing hair strand, hair delivers a lengthy history of alcohol and drug usage. Sampling hair near the scalp enables a detection window of up to approximately three months for various substances. Collection of hair is straightforward, moderately resistant to tampering, and convenient for shipping.

Using a 1.5-inch portion comprising nearly 200 hair strands (roughly equivalent to a #2 pencil) closest to the scalp yields 100mg of hair, an optimal sample size for analysis and validation. For EtG, additional screening, or tests exceeding 10-panel screens, a specimen weight of 150mg is advisable. Utilizing a jeweler’s scale for accurate measurement is suggested. Should scalp hair be unavailable, an equivalent amount of body hair can be obtained. The term "head hair" refers exclusively to scalp hair, while "body hair" signifies all other types of hair (such as facial or axillary).

Process Overview

The drug testing lab procedure encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the preliminary processing of samples within a lab's system. This step ensures the sample's seal integrity, assigns it a random LAN (Laboratory Accessioning Number), and completes any required supplementary data input outside the scope of an electronic chain of custody system.

Screening acts as an initial rapid assessment for substance misuse. Although a cost-effective measure to discount drug usage across most samples, a conclusive screen is necessary to legitimize results legally. Samples that test positive in Screening necessitate further confirmation.

If Screening indicates potential positive results, additional hair from the original sample is prepared for Extraction. This phase involves deriving drugs from hair at considerably reduced concentrations compared to other methods (e.g., urine or oral fluid), making hair testing a notably challenging technique.

Confirming a positive screen is executed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation as required. The complete lab procedure from Accessioning to Confirmation is conducted under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with shorter periods.
• Enhanced accuracy: Hair drug testing is resistant to tampering, reinforcing result reliability.
• Historical insight: It offers a comprehensive view of substance use over time, beyond recent activity.

Limitations:

• Delayed detection: It takes about 5-7 days for substances to become detectable in hair.
• Expense: Typically, hair drug tests incur higher costs than other testing forms.
• Result variability: Factors like hair color and growth rate can influence drug metabolite concentration in hair.

Note: Despite common references to "hair follicle tests," the examination involves analyzing the hair strand and 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.
