Hair Follicle Drug Testing - Mount Briar, MD

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the growing strand. When obtained near the scalp, hair offers about a 3-month window to detect alcohol and other substances. It's straightforward to gather, challenging to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (comparable to the width of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample size for both screening and verification. For EtG, additional tests, and/or panel tests exceeding 10, 150mg of the sample is advised. We suggest weighing the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be used. Here, head hair strictly refers to scalp hair only, while body hair encompasses all other types (facial, axillary, etc.).

Process Summary

The examination of a drug test outcome in a lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample within a lab's system. This step includes confirming that the sample was properly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry not addressed by an electronic chain of custody system.

Screening involves a preliminary swift assessment for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result in screening requires verification to be acceptable in legal settings. Any samples with a presumptive positive outcome in Screening necessitate secondary validation.

If a sample shows a presumptive positive result in the Screening phase, additional hair is extracted from the original sample for Extraction. During this phase, drugs are removed from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to conduct.

Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation when needed. The comprehensive laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests detect drugs used in the past 90 days, while urine tests have a more limited detection period.
• Hard to deceive: Manipulating a hair drug test is very difficult, leading to more reliable results.
• Historical insight: It can illustrate a pattern of drug consumption over time, not simply recent use.

Limitations:

• Inability to detect recent consumption: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than other testing approaches.
• Result variance: Factors like hair color and personal differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Often termed "hair follicle tests," the examination focuses on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Mount Briar, MD, hair follicle testing holds distinct advantages over urine testing. The detection window for hair testing can extend up to 90 days, while urine tests often miss longer-term drug use. This gives hair testing the edge in thoroughness.

Employers and institutions benefit from the comprehensive nature of hair testing. The longer detection period helps paint a more accurate picture of substance use, which urine testing cannot match.

Extended Detection Window

Hair follicle testing in Mount Briar, MD, extends the detection window to up to 90 days, providing a broader view of substance history. This duration starkly contrasts with urine testing, offering significant advantages for employers seeking thorough assessments.

The lengthened detection period allows employers to better evaluate a candidate's or employee's long-term substance use patterns, crucial for making informed decisions.

Tamper-Resistant Testing Method

In Mount Briar, MD, hair follicle tests are noteworthy for reducing sample tampering risks. Their reliability ensures results that are trustworthy and nearly impossible to adulterate compared to other testing methods.

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.
