Hair Follicle Drug Testing - Holloway Terrace, DE

What it is, How it works

Hair analysis is increasingly recognized as an efficient method for detecting drug and alcohol consumption. Hair captures a chronological record of drug and alcohol use by embedding biomarkers within the structure of the elongating hair strand. When trimmed near the scalp, hair can reveal a detection span of up to three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and easily transportable.

A segment of hair measuring 1.5 inches and comprising about 200 individual hairs (approximately a #2 pencil’s circumference) closest to the scalp yields roughly 100mg, the preferred amount for analysis and corroboration. For EtG enhancements, and/or assessments exceeding 10 panels, a 150mg specimen is advised. We advocate using a jeweler’s scale to measure the specimen. In cases where scalp hair isn’t accessible, an equivalent volume of body hair may be procured. When mentioning head hair, we strictly mean scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the preliminary processing of a specimen into the lab's framework. This includes confirming that the specimen was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data tasks not managed by an electronic chain of custody system.

Screening is the preliminary rapid assessment for any abusive substances. Though Screening provides a cost-effective approach to negate drug use in most samples, a conclusive result from a positive screen is mandatory for legal admissibility. Samples presumed positive during Screening require additional confirmation.

Should a sample test presumptively positive during Screening, additional hair is selected from the initial sample and made ready for Extraction. Here, drugs are extracted at lower concentrations compared to alternative methods (e.g., urine or oral fluid), which contributes to the heightened complexity of hair drug testing.

Confirmation of any presumptive positive finding occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All conclusive positive samples undergo cleaning prior to confirmation as required. The full laboratory procedure from Accessioning through to Confirmation is reviewed under the CAP (College of American Pathologists) Hair specification and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug consumption for up to 90 days, whereas urine tests provide a shorter detection span.
• Challenging to manipulate: Cheating a hair drug test is exceptionally difficult, enhancing result reliability.
• Chronological usage data: It reveals a pattern of substance use over time, not just recent use.

Limitations:

• Inability to detect recent use: Drugs typically require 5-7 days post-use to become traceable in hair.
• Expense: Generally, hair drug tests cost more than other drug testing options.
• Result disparities: Elements like hair color and individual hair growth rates can influence the concentration of drug metabolites in the hair.

Note: Referred to commonly as "hair follicle tests", these tests specifically analyze the hair shaft, and not the follicle embedded within the scalp.

Why Hair Follicle Testing Beats Urine Testing

Comparing hair follicle testing with urine testing in Holloway Terrace, DE, highlights significant differences. Due to its longer detection window, hair testing offers a superior overview of substance use.

Unlike urine tests, which capture recent consumption, hair tests can detect substance use up to 90 days prior. This longer window of detection is invaluable for employers aiming for more comprehensive insights into potential employees.

Extended Detection Window

Hair follicle testing is noted for its extended detection window in Holloway Terrace, DE, capable of identifying drug use up to 90 days past. This lengthier detection period supplies a broad overview of an individual's substance consumption history.

A major advantage of hair testing is the ability to provide employers with a long-term snapshot, helping in evaluating applicants or current personnel consistently and thoroughly.

Tamper-Resistant Testing Method

Hair follicle tests in Holloway Terrace, DE, offer an inherently tamper-resistant methodology. Unlike some alternative testing methods, these tests significantly reduce the potential for sample manipulation.

Through careful observation and collection procedures, hair testing provides outcomes that are trustworthy and difficult to contest, ensuring soundness and genuineness in test results.

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.
