Hair Follicle Drug Testing - Saint Marks, FL

What it is, How it works

Hair testing is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair acts as a historical record for alcohol and drugs by encasing biomarkers within the strands as they grow. Hair samples collected near the scalp offer detection for alcohol and drugs up to roughly three months. Hair collection is uncomplicated, relatively resistant to tampering, and easy to send for analysis.

Securing a 1.5-inch portion of around 200 hair strands (comparable to a #2 pencil) close to the scalp yields 100mg, which is the optimal amount for both initial and confirmatory testing. For EtG, add-ons, and tests over 10 panels, a sample of 150mg is advisable. We suggest utilizing a jeweler’s scale for accurate weighing. In the absence of scalp hair, an equivalent portion of body hair could be utilized. The term head hair exclusively denotes scalp hair. In contrast, body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the laboratory framework. This step ensures the sample was properly secured and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplemental data processing not covered by an electronic chain of custody system.

Screening entails a preliminary analysis for drugs of abuse. While it is a cost-efficient method for excluding drug use in most samples, positive screens require confirmation to be legally valid. Presumptive positive results in Screening necessitate subsequent confirmation steps.

Should a sample yield a presumptive positive result during Screening, additional hair is extracted from the initial sample for further Examination. During this phase, drug compounds are extracted from hair at a notably lower concentration than in alternative methodologies (e.g., urine or oral fluid), underscoring the challenge in performing hair drug screenings.

The Confirmation of any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples flagged as presumptive positives undergo washing before confirmation if necessary. The entire laboratory sequence, from Accessioning to Confirmation, is conducted under the scrutiny of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for a maximum of 90 days, as opposed to urine tests which have a limited detection period.
• Challenging to mislead: Hair drug tests are challenging to circumvent, enhancing result accuracy.
• Offers historical insights: It provides a timeline of drug use over months, not merely recent consumption.

Limitations:

• Inability to detect recent usage: Drugs only become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to cost more compared to other drug test methods.
• Result variability: Elements like hair color and individual hair growth differences can influence the drug metabolite concentration in hair.

Note: Despite commonly being termed as "hair follicle tests", the examination focuses on the hair strand rather than the follicle beneath the scalp
