Hair Follicle Drug Testing - Winhall, VT

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage by capturing biomarkers in the fibers of growing hair. Hair offers an extended overview of substance use when extracted near the scalp, providing a detection span of up to three months for alcohol and drugs. The collection process is straightforward, tampering is relatively tough, and shipping is uncomplicated.

Collecting a 1.5-inch segment of around 200 hair strands (akin to a #2 pencil) nearest to the scalp will yield 100mg, marking the optimal amount for screening and confirmation procedures. For tests including EtG, add-ons, or those beyond ten panels, a specimen weighing 150mg is advised. We suggest using a jeweler's scale for weighing the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair may suffice. The phrase "head hair" pertains specifically to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The process of laboratory testing for drug detection involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the lab’s system, ensuring the sample was properly sealed and transported, assigning it a random Laboratory Accessioning Number (LAN), and completing any extra data entry not included within an electronic chain of custody system.

Screening performs a primary check for substance abuse. Though it serves as a cost-efficient mechanism to eliminate drug presence in most samples, confirmed verification is essential for legal proceedings. Presumptive positives in Screening necessitate secondary validation.

Should the Screening indicate a presumptive positive, additional hair is taken from the original sample and prepped for Extraction. Here, drug elements are extracted from hair at much lower concentrations than in other techniques (example: urine or oral fluids), which contributes to the complexity of hair drug testing.

GC/MS, GC/MS/MS, or LC/MS/MS methods are implemented for confirming any positive screening outcomes. Any samples presumed positive are thoroughly cleaned before confirmation if required. From Accessioning to Confirmation, the whole lab sequence is subjected to review under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal substance use for as long as 90 days, surpassing the shorter detection timelines of urine tests.
• Difficulty to falsify: Hair drug testing is challenging to manipulate, enhancing the accuracy of results.
• History of substance use: It maps a history of drug usage over a defined span, as opposed to just recent consumption.

Limitations:

• Lacks ability to identify recent use: Drugs become noticeable in hair only after 5-7 days have passed.
• Expense: Typically, hair drug tests cost more than alternative testing methods.
• Results can vary: Elements such as hair pigmentation and personal hair growth variations can influence drug metabolite concentrations in hair.

Note: Commonly mistaken as "hair follicle tests," the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Winhall, VT, hair follicle testing is often preferred over traditional urine tests due to its superior detection accuracy and reliability. Hair tests can identify a wider range of substances and provide a more comprehensive view of an individual's drug use history.
