Hair Follicle Drug Testing - Oakhurst, OK

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol intake. The hair retains a lasting record of alcohol and other substances by encapsulating biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can offer a detection timeframe of up to about three months for alcohol and various drugs. The collection process for hair is straightforward, moderately resistant to tampering, and simple to transport.

A sample of hair measuring 1.5 inches, consisting of around 200 strands (comparable to the size of a #2 pencil) taken nearest to the scalp, yields 100mg of hair, the preferred quantity for both screening and validation. For EtG, additional tests, and/or panels over 10, a 150mg specimen is advisable. Utilizing a jeweler’s scale to measure the specimen's weight is recommended. If scalp hair cannot be obtained, an equal quantity of body hair can be used. By head hair, we mean solely scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

There are four key stages in the lab analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial process of integrating a sample into a lab’s system. This process verifies that the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data input not accounted for by an electronic chain of custody system.

Screening consists of a preliminary inspection for drugs of abuse. While Screening is a cost-effective method to exclude drug usage in most samples, any positive results necessitate confirmation to be valid in legal settings. Samples showing presumptive positivity in Screening must undergo a subsequent confirmation.

For samples showing presumptive positivity during Screening, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, substances are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug analysis the most challenging technique to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positivity are cleaned prior to confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, adheres to 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 identify drug usage for up to 90 days, unlike urine tests which have a limited detection period.
• Resistant to cheating: Manipulating a hair drug test is notably challenging, enhancing result accuracy.
• Presents past data: It reveals a drug use pattern over time, rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be costlier than alternative drug testing methods.
• Result variations: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the analysis actually targets the hair strand, not the follicle beneath the scalp.
