Hair Follicle Drug Testing - Grandview, OK

What it is, How it works

Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a longitudinal record of substance use by embedding biomarkers within the hair strands as they grow. When samples are harvested near the scalp, they can offer a detection timeline of up to three months for alcohol and substances. Hair is straightforward to gather, relatively tamper-resistant, and easy to transport.

A 1.5-inch hair segment consisting of roughly 200 strands (about the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a 150mg specimen is preferable. It's advisable to use a jeweler’s scale to weigh the specimen. If scalp hair isn't accessible, an equivalent quantity of body hair can be used. Reference to head hair pertains exclusively to scalp hair. Body hair encompasses all other forms of hair (facial, axillary, etc.).

Process Overview

The primary steps in processing a drug testing result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the preliminary handling of a sample within a lab's system. This phase ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.

Screening performs an initial rapid assessment for substance abuse. While screening is a cost-efficient way to negate drug use in most samples, a positive result must be verified to be legally valid. Any sample indicating a presumptive positive during screening necessitates further confirmation.

Should a sample test presumptively positive at the Screening phase, additional hair is extracted from the original specimen for the Extraction process. This phase involves extracting substances from hair at concentrations much lower than other methods like urine or oral fluid, which makes hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening finds is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every presumptive positive sample is pre-washed before confirmation if required. The entire lab process, from Accessioning through to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation and is accredited under the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can reveal drug use for as long as 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is highly challenging, enhancing result accuracy.
• Yields historical usage data: It can show a drug usage trend over time rather than just recent use.

Limitations:

• Unable to depict recent use: Drugs require around 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though often called "hair follicle tests", the testing is conducted on the hair strand, not the follicle beneath the scalp.
