Hair Follicle Drug Testing - Vick, TX

What it is, How it works

Utilized as an effective mechanism, hair testing effectively detects drug and alcohol consumption. Hair encapsulates a protracted chronicle of alcohol and drug usage by embedding biomarkers within the hair strand's fibers. When procured adjacent to the scalp, hair boasts a detection timeframe extending up to roughly three months for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is uncomplicated.

A 1.5-inch segment consisting of approximately 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg, the prime sample for both screening and confirmation. For EtG, additional components, or tests exceeding 10 panels, a specimen of 150mg is advised. We endorse weighing the specimen using a jeweler’s scale. In the absence of scalp hair, an analogous quantity of body hair may be obtained. When discussing head hair, we imply strictly scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test entails four cardinal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially processing a sample into the laboratory system. This phase encompasses verifying that the sample was sealed and transmitted correctly, attributing a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry absent in an electronic chain of custody system.

Screening constitutes a preliminary expedited assessment for drugs of abuse. While Screening is economically efficient for eliminating drug usage in the bulk of samples, a positive screen necessitates confirmation for court admissibility. Any samples presumed positive during Screening mandate secondary confirmation.

If a sample appears presumptively positive in Screening, additional hair is extracted from the initial specimen and configured for Extraction. At this stage, drugs are extracted from hair at notably lower concentrations than other procedures (e.g., urine or oral fluid), contributing to hair drug screening being the most arduous methodology to execute.

Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo necessary washing before confirmation. The comprehensive laboratory process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug tests ascertain drug usage up to 90 days, whereas urine tests possess a shorter detection period.
• Resistance to manipulation: Cheating a hair drug test is highly challenging, ensuring more precise results.
• Conveys past usage data: It delineates a pattern of drug use over a duration, not solely recent consumption.

Limitations:

• Inability to recognize recent usage: Detectability of drugs in hair arises roughly 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs compared to other drug testing techniques.
• Result variability: Elements like hair color and individual hair growth variances can impact drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests", the test itself evaluates the hair strand, not the hair 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.
