Hair Follicle Drug Testing - Annville, KY

What it is, How it works

Hair analysis is now acknowledged as a potent method for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and drug use by encapsulating biomarkers within the fibers of the hair strand as it grows. Collected near the scalp, it can provide a detection window of up to around 3 months for alcohol and other drugs. Hair collection is straightforward, relatively tamper-proof, and easy to transport.

A sample measuring 1.5 inches, or about 200 hairs (resembling the thickness of a #2 pencil) nearest the scalp will yield 100mg, the recommended quantity for examination and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is suggested. Utilizing a jeweler’s scale to weigh the sample is advisable. If scalp hair isn't accessible, an equivalent portion of body hair can be utilized. When we mention head hair, we exclusively mean scalp hair. Body hair includes other types (like facial or underarm hair).

Process Overview

The laboratory processing of drug test results involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a sample into a laboratory’s framework. This step ensures the sample was correctly sealed and sent, assigns an arbitrary LAN (Laboratory Accessioning Number), and finishes any data entry missing from an electronic custody chain system.

Screening is a preliminary rapid assessment for drug presence. Although Screening is a cost-efficient method to ascertain drug use in most samples, a positive result must be confirmed for legal validity. Samples suggesting positivity in Screening necessitate subsequent confirmation.

If a Screening stage result is preliminarily positive, extra hair is extracted from the original sample and readied for Extraction. Here, drugs are extracted from hair at a reduced concentration level compared to other methods (such as urine or oral fluid), rendering hair drug tests the most challenging to administer.

Confirmation of any positive screen result entails GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumed positive samples are cleansed before confirmation if needed. Each step, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use up to 90 days, as opposed to urine tests with a shorter detection period.
• Tough to falsify: Hair drug tests are extremely difficult to manipulate, ensuring more precise results.
• Reflects use history: It provides a usage pattern over an extended duration, not just recent consumption.

Limitations:

• Not suitable for recent use detection: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug tests typically incur higher costs compared to other testing techniques.
• Result variability: Variables like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Commonly known as "hair follicle tests", they actually assess 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.
