Hair Follicle Drug Testing - Kensington, MD

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and drug use by embedding biomarkers within the hair strand's fibers as it grows. When gathered near the scalp, hair can reveal a detection period of up to about three months for both alcohol and drugs. Collecting hair is straightforward, difficult to tamper with, and simple to transport.

A 1.5-inch section consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal amount for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a specimen amount of 150mg is suggested. It's advisable to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair can be utilized. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The key steps in laboratory processing for drug test results consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a laboratory's workflow. This process involves confirming that the sample was sealed and transported correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplemental data entry not covered by an electronic chain of custody system.

Screening represents an initial rapid assessment for drugs of abuse. Although Screening is an economical method to exclude drug use in most samples, a positive result requires confirmation for court admissibility. Any samples with a presumptive positive result in Screening need additional verification.

For samples with presumptive positives in Screening, more hair is taken from the initial sample and prepped for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug analysis is one of the most challenging methodologies to execute.

Verification of any positive screening outcomes is performed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a 90-day span, unlike urine tests, which have a smaller detection window.
• Hard to defraud: It is extremely difficult to fabricate a hair drug test, ensuring more accurate results.
• Delivers historical insight: It can showcase a timeline of drug use over an extended duration, not just recent usage.

Limitations:

• Incapable of identifying recent use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests are typically more costly than other drug testing approaches.
• Result variations: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly described as "hair follicle tests", the analysis targets the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers numerous advantages over traditional urine tests in Kensington, MD. Unlike urine tests, hair examinations can identify drug use extending beyond a few days, revealing a pattern of usage. This superior detection capability provides a clearer picture of an individual’s substance history.

Comparative Benefits: While urine tests detect recent drug use, hair testing surpasses them with a significantly longer detection time, offering greater reliability and accuracy.

Extended Detection Window

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.
