Hair Follicle Drug Testing - Tiptop, VA

What it is, How it works

Using hair as a testing medium has become recognized as an effective method for detecting drug and alcohol consumption. The growing hair contains fibers that can encapsulate biomarkers, thereby offering a chronological record of alcohol and drug exposure. When hair strands are collected near the scalp, they can present a detection timeframe extending up to roughly 90 days for both alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.

A hair sample measuring 1.5 inches with around 200 strands (comparable to the diameter of a #2 pencil) near the scalp will yield 100mg of hair, which is ideal for both screening and confirmation testing. For EtG, additional tests, or those exceeding 10 panels, it is advisable to gather 150mg of the sample. It is recommended to measure the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be gathered. The term head hair specifically refers to hair on the scalp, while body hair encompasses other hair types (such as facial and axillary).

Overview of Process

The laboratory processing of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase involves the initial integration of a sample into the lab's system. This phase includes ensuring the sample's seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from the electronic chain of custody.

In the Screening phase, a swift preliminary examination for drug usage is performed. Although Screening serves as a cost-effective method to eliminate drug consumption in most cases, a positive screen requires confirmation to be legally accepted. Samples that yield a presumptive positive during Screening necessitate further confirmation.

Should a sample exhibit presumptive positivity in the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at concentrations lower than found in other testing methods (for example, urine or oral fluid), which is why hair drug testing poses significant challenges.

Positive findings from the Screening stage are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmatory testing, samples with presumptive positivity undergo washing as necessary. The entire laboratory process, from Accessioning to Confirmation, undergoes a review under the CAP (College of American Pathologists) guidelines for Hair designation and is accredited following ISO / IEC 17025 standards.

Benefits of Hair Drug Testing:

• Extended detection timeframe: Hair drug tests can identify drug use over a 90-day period, contrasted with urine tests that have a shorter timeframe.
• Resistance to tampering: Cheating a hair drug test is extremely challenging, thus enhancing result accuracy.
• Historical usage information: It reveals a pattern of drug use across time, not limited to recent usage.

Drawbacks:

• Inability to detect recent usage: Drugs require approximately 5-7 days to become traceable in hair.
• Expense: Hair drug tests often incur higher costs compared to alternative testing methods.
• Result variability: Factors such as hair color and individual variations in hair growth can influence drug metabolite concentrations in hair.

Note: Despite being commonly termed "hair follicle tests", these tests evaluate the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
