Hair Follicle Drug Testing - Colesville, MD

What it is, How it works

Recognized as a potent method, hair testing is highly effective in uncovering drug and alcohol consumption. By capturing biomarkers within the fibers of the hair strand as it grows, hair can reflect a timeline of alcohol and other drugs over an extended period. Hair collected close to the scalp provides a potential detection timeframe of up to three months for such substances. The collection of hair is straightforward, challenging to falsify, and simple to transport.

A segment measuring 1.5 inches comprising roughly 200 hair strands (equivalent to the thickness of a #2 pencil) gathered nearest the scalp yields approximately 100mg of hair, which is ideal for screening and confirmation processes. For EtG tests, additional analyses, and/or tests exceeding 10 panels, it is suggested to collect 150mg of hair. Utilizing a jeweler’s scale to weigh the hair sample is advocated. If scalp hair is unavailable, an equivalent weight of body hair may be collected. When we indicate head hair, it exclusively refers to scalp hair, whereas body hair includes all other hair types (such as facial, axillary, etc.).

Process Summary

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

Accessioning corresponds to the initial processing phase where a sample is integrated into the laboratory’s system. This phase entails verifying that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and addressing any supplementary data entry absent an electronic chain of custody system.

Screening involves conducting a preliminary swift evaluation for drugs. Screening serves as a cost-efficient method to identify drug use for most samples, although a positive screen result must be reconfirmed for it to be accepted legally. Any samples that test presumptively positive during Screening necessitate a secondary confirmation.

Should a sample be shown to be presumptively positive at the Screening phase, additional hair is taken from the original sample for the Extraction phase. Here, the focus is on extracting drugs from hair at significantly lower concentrations than in other methods (such as urine or oral fluids), contributing to the demanding nature of hair drug screening.

Confirmation of any screen-positive result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples undergo washing if needed before confirmation. The entire lab procedure, spanning from Accessioning to Confirmation, is scrutinized both under CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use up to 90 days prior, whereas urine testing offers a shorter detection period.
• Testing integrity: The difficulty in deceiving a hair drug test enhances result accuracy.
• Usage history: Offers insights into drug consumption patterns over time, beyond just recent use.

Drawbacks:

• Limited in detecting recent use: Drugs take roughly 5-7 days to become detectable in hair strands.
• Expensive: Hair drug testing typically incurs higher costs versus alternative drug testing methods.
• Variable outcomes: Factors such as hair color and individual differences in hair growth may influence drug metabolite concentrations within hair.

Note: Although commonly labeled as "hair follicle tests", the analysis focuses on the hair strand itself rather than 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.
